Document Type and Number:
Japanese Patent JP2769781
Kind Code:
B2
Abstract:
PURPOSE: To hold a large elastic force at the time of accumulating the pressure of a piston and to manually continuously use it even if it is stopped during using by motor driving.
CONSTITUTION: In the case of using by motor driving, the rotating motion of a crank disc 91 is converted to the sliding motion (linear motion) of a converter 12 via a connecting arm 10 and a rocking arm 11. A pressure-accumulated piston 15 is held by a motor driven shear rod 131 and a motor driven shear 132. A bullet A is shot by the elastic force of a piston spring 151. In the case of using manually, the piston 15 is moved by a manual coking handle bar 16, and held by a manual cocking shear 17 and a manual cocking shear rod 18. When the using by the motor driving is stopped, the bar 16 is moved, and manually moved from the stopped place.
