267869 of the present inventor in view that the lamp body connected to the main body comprising a dry battery case is invented to be laid parallel to the main body whereby the irradiation range of the flashlight worn on the wrist can be widened.

BACKGROUND ART In the prior invention of the present inventor, the wrist flashlight is constructed that a wrist band is connected to the main body comprising a dry battery case ; the main body is attachable to a lamp body in order that the irradiation angle of the lamp can be controlled ; the auxiliary body which can be worn separately on the waist is electrically connected to the main body by a power code and comprised of the connecting structure which can be joined to the lamp body, whereby the separate potable flashlight function other than the wrist flashlight function can be produced. However, the prior present Invention has problems that the lamp can be pivotally rotated only within the limited angle range by the ball shape jack inserted in the monotube type cathode connecting member fixed on the main body, that is, the prior invention has not the function of putting the lamp on the main body in accord with the length direction of the main

body so that the irradiation of the lamp in the state of the flashlight worn on the wrist is primarily directed to the front of the main body which is the wrist direction, thus, due to the limit of the irradiation range, when it is in the practical use, for example, when it is used in the situation that one hand wearing the flashlight is holding a fishing-rod and the other hand is needed for another work like tempering some paste bait, the light from the flashlight is put only to the fishing-rod so that the other work becomes impossible and the work limit or the work inconvenience are caused ; and also that: since the lamp body is projected from the front end of the main body and is not foldable, the whole length can not be reduced even when it is not used so that it is inconvenient in carrying or keeping, that is the obstacle of the miniaturization thereof.

DISCLOSURE OF THE INVENTION Therefore, this present invention is to solve the problems, and the object of the invention provides a wrist flashlight easy in carrying and keeping by that: the irradiation range is wider than before to improve the effect and the convenience in using ; the lamp body can be completely folded in the close adhesion state so that the whole size can be reduced according to the necessity.

To achieve the above object, the present invention suggests the lamp body comprising the ball shape jack at the one end thereof.

In addition, the present provides a main body comprising a connecting structure which is selectively and electrically attachable to the above jack ; a dry battery case; a switch structure ; and a folding-attaching induction groove and so on, the folding-attaching induction groove being made by folding the one part of the monotube type cathode connecting member for making the lamp body closely laid on the main body at a position.

Fig. 5 is an exemplary view showing the bottom of the flashlight according to the present invention MODES OF CARRYING OUT THE INVENTION The wrist flashlight of the present invention is classified in, as shown in Fig. 2, the lamp body 10 being the lighting function ; the case of the battery supplying the power to the lamp ; and the main body supporting the above lamp body 10, the lamp body 10 comprising the lamp 13 protected by the protecting window 12 in the case 11, the jack 14 electrically connectable to the lamp 13 is installed at the one end of the case 11,

the above jack 14, in order for the cathode and the anode of the dry battery to be applied, is constructed as that: the conductive anode part 14a and cathode part 14b are divided in the mutual insulating state; the anode part 14a is elastically contacted to the conductive bar 15 connected to the anode leading line 13a of the lamp 13 by the spring 16 ; and the cathode part 14b is contacted by the conductive spring 17 connected to the cathode leading line 13 b of the lamp 13.

While, in the upper side of the body 22 of the main body 20 in which the dry battery can be received, the above jack 14 is movably connected and the mono tube type connecting structure 21 is fixed.

The cathode jack 21 b is installed in the one side of the connecting structure 21, the cathode jack 21 b being connected to the positive terminal 32 of the base plate 30 to which the cathode power of the dry battery is applied in the state of connecting closely to the cathode part 14b of the above jack 14. The negative jack 21 a is installed on the front of the base plate 30, the negative jack 21 a being connected to the negative terminal 31 of the base plate 30 to which the anode power of the dry battery is applied in the state of contacting elastically to the anode part 14a of the above jack 14.

Also, in order that the tamp body 10 bound to the above connecting structure 21 is laid closely with the case 22 at a position, the one part of the mono tube type connecting structure 21 is folded in the side direction to produce the folding-attaching induction groove 23.

In above, the anode part 14a and the cathode part 14b of the jack 14 are consisted to have sufficient insulating structure, the

anode jack 12a and the cathode jack 12b are properly positioned in order to be contacted always to the same polar part without contacting to the other polar part even if the jack 14 is rotated in any direction and any range.

Also, the switch 24 controlling selectively the power of the dry battery which is to be applied to the base plate 30 is set in the one part on the body 22 of the main body 20, and as shown in Fig. 6, in the both bottom part of the main body 20, the groove 40 and the fastening pin 41 which can be connected to the known wrist band b for wearing the main body 20 on the wrist.

The operation of the present invention constructed as above will be described in more detail as below.

To make the wrist flashlight of the invention, first of all, the jack 14 of the lamp body 10 is connected to the connecting structure 21 of the main body 20 as shown in Fig. 2.

As connected above, the anode part 14a of the jack 14 is contacted elastically to the anode jack 21b installed in the negative terminal 31 of the base plate 30 and the cathode part 1 b is contacted closely to the cathode jack 21b installed in the connecting structure 21, whereby the power of the dry battery is applied.

After connecting the lamp body 10 and the main body 20 as above, the known wrist band 24 is worn by the fastening pin 41 formed in the cover 23 of the main body 10.

As shown in Fig. 4, it is worn for the main body 20 to be positioned under the wrist and then the switch 24 is turned"on"to apply the batter power to the lamp 13 for lighting.

While, as the irradiation direction of the lamp 13 can be

controlled at user's option, if an user moves the lamp body 10, the lamp body 10 is rotated in the connecting structure 21 of the main body 20 as the fixing axis so that the direction of the lamp body 13 can be freely converted even in the rotation state, the anode part 14a and the cathode part 14b are constructed not to be gotten out of the anode jack 12a and the cathode jack 21 b, whereby the electrical short is prevented.

On the other hand, in case that the irradiation direction of the lamp 13 is required to be in accord with the arm's direction, as shown in Fig. 2, let the lamp body 10 be in accord with the position of the folding-attaching induction groove 23 and then pressed down to be inserted into the space thereof, whereby the lamp body 10 can be folded and attached completely laid on and parallel. to the upper side of the body 22, thus, the irradiation direction of the lamp 13 is in accord with the wrist's direction. Therefore, when the flashlight is not used, if it is put in the state as above, its volume is reduced and becomes easy to carry and keep.

As shown in Fig. 3, in the state that the lamp body 10 is not inserted in the folding-attaching induction groove 23, when the irradiation direction is quite different from the arm's, that is, the irradiation direction makes a right angle with the arm's or it is in the similar range thereof so that the irradiation range of the lamp can be effectively extended.

While, the wrist flashlight of the present invention can be variously used in other than night-fishing such that the working is done in the dark and narrow space.

INDUSTRIAL APPLICABILITY As above, the present invention is to improve the electrical connecting structure and the connecting structure of the wrist flashlight so that the lighting of the lamp is possible even in the state that the lamp body is completely folded and attached, whereby the irradiation range becomes wider than before to elevate the using effect and the management thereof becomes easy. If necessary, the occupation space of a machine can be reduced to raise the effect of carrying and keeping.
