The rotating rod 321 is provided on the inner wall of the rotating sleeve 311. The end of the rotating rod 321 is provided on the cutting blade 325.

A drive sliding groove 324 is provided on the side wall of the rotating ring 312. The limiting slide post 322 passes through the telescopic slide groove 323 and is inserted into the drive slide groove 324; Furthermore, the telescopic cutting component 32 includes a rotating rod 321. The rotating sleeve 311 is rotatably connected to the rotating rod 321 via a rotating shaft on the inner wall near the rotating ring 312. A cutting blade 325 is fixedly connected to the side of the rotating rod 321 away from the rotating shaft and close to the rubber sleeve 1. A telescopic groove 323 is provided on the side wall of the rotating sleeve 311 near the rotating ring 312. A driving groove 324 is provided on the rotating ring 312 outside the telescopic groove 323. A limiting slide post 322 is fixedly connected to the side wall of the rotating rod 321 near the rotating ring 312. One end of the limiting slide post 322 near the rotating ring 312 passes through the telescopic groove 323 and is slidably connected in the driving groove 324. The limiting slide post 322 is slidably connected to the telescopic groove 323. When in use, the separating heating wire 214 and the spiral heating wire 223 are charged. At this time, the spiral heating wire 223 heats the cable at the outer end of the cable, and the separating heating wire 214 heats the cable from the center of the cable, thereby achieving sufficient heating of the cable and ensuring normal use of the cable in cold environments. When a cable needs to be connected, push the sliding block 314 away from the rotating ring 312. After the sliding block 314 disengages from the locking protrusion 313, it grips the rotating sleeve 311 and rotates the rotating ring 312 through the locking protrusion 313. The rotating ring 312 drives the drive groove 324 to rotate around the rubber sleeve 1. While rotating, the drive groove 324 presses the limiting slide post 322 towards the rubber sleeve 1. Under the limitation of the telescopic groove 323, the limiting slide post 322 drives the rotating rod 321 towards the rubber sleeve 1. The rotating rod 321 drives the cutting blade 325 to rotate and insert into the rubber sleeve 1. At this time, the sliding block 314 is pushed to re-engage within the spacing of the locking protrusion 313, thus locking the rotating sleeve 311 and the rotating ring 312. Then, the sleeve 311 and the rotating ring 312 are rotated simultaneously. At this time, the rotating sleeve 311 drives the cutting blade 325 to perform a ring cut on the rubber sleeve 1. Then, the cut-off rubber sleeve 1 is removed, thus completing the convenient cutting of the outer wall of the rubber sleeve 1. After the rubber sleeve 1 is peeled off, pull out the spiral heating wire 223 that needs to be removed. At this time, pull the separating heating wire 214 in the direction between the main wires 211. The separating heating wire 214 splits the heat-conducting filler 213. Then pull the separating heating wire 214 to separate the ground wire 212 from the main wire 211. At this time, the main wire 211 and the ground wire 212 can be separated. This completes the pre-treatment of the cable. Since the heat-conducting filler 213 is cut by the separating heating wire 214, the main wire 211 and the ground wire 212 can be easily cut and separated without cutting tools.
