The lower surface of the upper cover 1 is concavely provided with a guide groove 11. The floating plate 3 is arranged in the guide groove 11. The floating plate 3 is connected to the upper cover 1 through the guide assembly 6. The guide assembly 6 provides a downward driving force for the floating plate 3. The fixed knife seat 4 and the adjusting knife seat 5 are arranged on the floating plate 3. The adjusting knife seat 5 moves along the floating plate horizontal 3 to adjust the distance between the fixed knife seat 4 and the adjusting knife seat 5. The blade 7 is installed on the fixed knife seat 4 and the adjusting knife seat 5. The side of the upper cover 1 is provided with a guide groove 12.

[0026] When in use, the upper cover 1 and the lower cover 2 are separated, the cable is placed in the arc-shaped groove 21, the upper cover 1 is closed on the lower cover 2, and the blade 7 is pressed tightly against the cable by the driving force of the guide assembly 6. The staff also needs to hold the cable and the skin cutter, rotate the skin cutter, cut off the insulation layer with the blade 7, and then insert a utility knife or other tool into the guide groove 12, and cut the insulation layer axially along the guide groove 12; after completion, remove the upper cover 1 and the lower cover 2. At this time, the insulation layer at the broken skin is separated from the overall insulation layer, and the insulation layer at the broken skin can be directly peeled off.

[0027] In one embodiment, if Figure 1-Figure 7 As shown, the guide assembly 6 includes a guide rod 61 and a first spring 62. The upper cover 1 is provided with a guide hole, the guide rod 61 is slidably arranged in the guide hole, the first spring 62 is arranged on the guide rod 61, the lower end of the guide rod 61 is connected to the floating plate 3, and the first spring 62 acts on the floating plate 3 and the bottom of the guide groove 11; the upper end of the guide rod 61 is provided with a limit portion 63. Through the above structure, the guide rod 61 is passed through the guide hole, and then the first spring 62 is sleeved on the guide rod 61, and then the floating plate 3 is connected to the guide rod 61 to complete the assembly, and the first spring 62 acts on the floating plate 3.
