CABLE DRAWING DEVICE
Document Type and Number:
Japanese Patent JP3445940
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To grant cable gripping force corresponding to the types of cables to be drawn with one device.
SOLUTION: A springing force adjustment mechanism 40 which is provided with a stopper 41 capable of hooking in position the other arm 22b to be engaged with a second cable feed portion 5 of one torsional coil springs 22 each of two incoming-line side torsional coil springs 22 and two outgoing-line side torsional coil springs 22 is provided for a thrust energizing means 6 consisting of four torsional coil springs 22 for thrust energizing the second cable feed portion 5 to a first cable feed portion 3. In this way, the spring force of one torsional coil springs 22 each of two incoming-line and outgoing-line side torsional coil springs 22 each are prevented from being transmitted to the second cable feed portion 5, thus changing cable gripping force corresponding to the types of cables.
