[0039] By adopting the above technical solution, the arc-shaped clamping plate 206 clamps the cable.

[0040] Working principle: First, manually rotate the threaded rod 306 according to the required circumcision. The threaded rod 306 moves downward under the action of the thread of the rotating frame 301. The threaded rod 306 moves downward through the second rotating block 305 to drive the tool holder 304 to rotate downward with the rotating connection with the circumcision adjustment device 3 as the axis. After the tool angle is adjusted, pass the cable through the rotating frame 301 to make the circumcision position correspond to the position of the tool holder 304;

The connecting rod 216 drives the two sliding blocks 203 to move under the guidance of the No. 1 pulley 210 and the No. 1 slide groove 211. The sliding block 203 moves to push the lifting block 204 to drive the lifting frame 205 to move upward synchronously.

The lifting block 204 and the two rotating rods 207 turn over and move centripetally, and the inner wall of the arc clamping plate 206 contacts the surface of the cable to clamp and fix the cable, thereby ensuring the stability of the cable during the ring cutting process;

[0042] Finally, the driving motor 601 is controlled to be turned on. The driving end of the driving motor 601 drives the rotating shaft 602 to rotate through the synchronous wheel transmission group. The rotation of the rotating shaft 602 drives the rotating gear 603 to rotate. The rotating gear 603 drives the rotating frame 301 to rotate through the gear ring 302. The cable is cut by the rotation of the rotating frame 301.
