The cable cutter 21 shown in FIG. 7 includes a cylindrical joint 22, a fixed blade 23 provided on an upper part of the joint 22, and a movable blade 25 which is axially mounted on a shaft 24 provided on the fixed blade 23. The fixed blade portion 23 is provided with a fixed blade 23a, and the movable blade portion 25 is provided with a movable blade 25a. Further, a sector gear 27 meshing with the drive gear 26 is provided on the outer periphery 25 b of the movable blade 25. A drive shaft 28 is inserted into the joint 22, and the rotation of the drive shaft 28 is transmitted to the drive gear 26 via a gear mechanism (not shown).

業効率が悪かった。Therefore, every time the sector gear 27 is disengaged from the drive gear 26, as shown in FIG. 9 (b), the operator manually engages the left end 27b of the sector gear 27 with the drive gear 26. Until then, the movable blade 25 had to be rotated and pushed back in the direction of arrow G in the figure, resulting in poor work efficiency.

7 may come off the drive gear 26 in some cases. At that time, as shown in FIG. 10B, the operator manually moves the movable blade 25 in the direction of arrow H in the figure until the right end 27a of the sector gear 27 and the driving gear 26 mesh with each other. Work efficiency was poor because it had to be rotated and pushed back.

Was mounted on the tip of Therefore, when the sector gear 27 is disengaged from the drive gear 26, the worker 30 cannot reach the movable blade 25, so the worker 30 rotates the movable blade 25 by hand and pushes it back to move the sector gear 27 to the drive gear 26. Could not be engaged.

Each time is disengaged from the drive gear 26, the operating rod 16 is pulled, the movable blade portion 25 is manually rotated and pushed back, and the sector gear 27 meshes with the drive gear 26.
Since the useless operation of sending out No. 6 has to be repeated, the working efficiency was very poor.

作業に移行できる。With this configuration, when the movable blade portion or the protrusion member presses the elastic member and the rotation advances, when the movable blade portion is fully opened and fully closed, the engagement between the sector gear and the drive gear is achieved. Is momentarily disengaged, so that the rotation of the drive gear is not transmitted to the sector gear. Therefore, no excessive force is applied to the sector gear and the drive gear, so that the drive gear and the sector gear can be prevented from being damaged. After the engagement between the sector gear and the drive gear is released, the movable blade portion is pushed back by the restoring force of the elastic member, so that the sector gear can immediately mesh with the drive gear again. Therefore,
Then, if the drive gear is rotated in the reverse direction, the operation can be immediately shifted to the subsequent operation.

る。First, as shown in FIG. 2 (a), the drive gear 11 is rotated in the direction of arrow A in the figure, and the movable blade 6 is rotated in the direction of arrow A 'in the figure. On the other hand, the movable blade 6a is fully opened. The fixed blade 4a and the movable blade 6
A wire (not shown), which is a workpiece, is inserted between a and a.

転は扇形歯車１２に伝達されない。Since the sector gear 12 is provided only up to the starting end 12a, the curved portion 6b of the movable blade 6 presses the elastic member on the outer periphery of the stopper 14, and the rotation of the movable blade 6 proceeds. At this time, the engagement between the start end 12a of the sector gear 12 and the drive gear 11 is disengaged for a moment. Therefore, when the rotation of the movable blade portion 6 advances, the rotation of the drive gear 11 is not transmitted to the sector gear 12.

１１とすぐに再び噛み合うことができる。したがって、
その後すぐに切断作業に移行することができる。After the engagement between the starting end 12a of the sector gear 12 and the drive gear 11 is released, the movable blade portion 6 is pushed back in the direction to close the movable blade 6a by the restoring force of the elastic member on the outer periphery of the stopper 14. The sector gear 12 can immediately re-engage with the drive gear 11. Therefore,
After that, the operation can be shifted to the cutting operation immediately.

易に切断される。At this time, as a result of the rotation input from the drive shaft 7 being reduced by the spiral miter 8 and the spiral miter 9, a strong rotation torque is generated in the drive gear 11, and the rotation torque is generated by the sector gear 12. It is transmitted to the movable blade 6. Therefore, the fixed blade 4a and the movable blade 6
The wire rod sandwiched between “a” and “a” is easily cut by the rotation of the movable blade portion 6.

い。Further, since the sector gear 12 is provided only up to the terminal end 12b, when the projection member 13 presses the elastic member on the outer periphery of the stopper 14 and the rotation of the movable blade portion 6 proceeds, the sector gear 12 End 12b of gear 12 and drive gear 1
The engagement with 1 comes off for a moment. Therefore, as in the case where the movable blade 6 is fully opened, when the rotation of the movable blade 6 advances, the rotation of the drive gear 11 is not transmitted to the sector gear 12.

The sector gear 12 is the drive gear 1
One can immediately re-engage. Therefore, after that, if the drive gear 11 is rotated in the reverse direction, the movable blade portion 6 is opened, and the next cutting operation can be started immediately.
