[0022] Working principle

[0023] When it is necessary to cut the damaged insulating layer in the cable 7, only need to pass the cable 7 through the circular track 9, so that the insulating layer at the damaged part is located between the two support frames 5. Then rotate the second rotating handle 11 to make the second sleeve 23 rotate, so that the screw rod 22 moves downward, and make the cutting knife 4 insert into the damaged part. When the bottom of the cutting knife 4 is in contact with the inner wall of the insulating layer, tighten the first fastening bolt 14 to fix the support block 12. Then move the support member 3 to make the cutting knife 4 perform axial cutting. Then move the cutting knife 4 to the end of the damaged part of the insulating layer, and then tighten the second fastening bolt 2 to fix the circular track 9. Then press the bullet head of the V-shaped elastic piece 17, and rotate the first rotating handle 15 to make the bullet head of the V-shaped elastic piece 17 pop out from another through hole 16 on the adjusting column 19. Then loosen the first fastening bolt 14, push the moving seat, and make the moving seat rotate circumferentially along the circular track 9, so that the cutting knife 4 performs circumferential cutting on the end of the insulating layer. When axial cutting is completed on both ends of the insulating layer at the damaged part, the damaged insulating layer can be taken out. Then the heat-shrinkable insulating layer can be sleeved on the cutting part, and then baked with a blowtorch to achieve the repair of the insulating layer. Therefore, during the use of this utility model, the stability of the cutting depth of the axial cutting and circumferential cutting of the insulating layer is ensured. Thus, the problem that when using the method of manually holding scissors or a small knife to peel a relatively thick insulating layer, the cutting depth of the scissors or the small knife is difficult to control and damage the internal cable 7 is eliminated.
