[0031] When stripping the wire, insert the cable into the two annular blades 18 from one side horizontally. At this time, start the drive motor 13 and drive the annular blades 18 on both sides to rotate along the cutting shaft 14 through the drive gear 15. At this time, the insulation skin can be cut from both sides parallel to the cable axis, which is convenient for taking out the long section of the wire core. The continuously rolling annular blade 18 continuously cuts by extrusion, and more parts are in contact with the insulation skin, preventing the blade from contacting the insulation skin at only one place, resulting in severe wear and causing jamming. At the same time, the base of the blade will roll and squeeze the cable to prevent the cable from being jammed due to friction.

[0032] In this embodiment, an idler wheel 16 is rotatably connected below the cutting table 4, and both ends of the idler wheel 16 are respectively engaged with the driving gear 15.

At this time, the insulation skin can be cut from both sides parallel to the cable axis, which is convenient for taking out the long section of the wire core. The continuously rolling annular blades 18 continuously cut by extrusion, and more parts are in contact with the insulation skin, which prevents the blade from contacting the insulation skin at only one place, resulting in severe wear and causing jamming. At the same time, the base of the blade will roll and squeeze the cable to prevent the cable from being jammed due to friction.

[0040] The idler wheel 16 allows the annular blades 18 on both sides to rotate simultaneously, applying force to the cable more evenly, so that the cutting effect on both sides is consistent;

[0041] The rubber bottom sleeve 17 and the cutting top sleeve 19 can support the cable from both sides, so that the cable axis is aligned with the annular blade 18, thereby improving the slitting effect. At the same time, the annular blade 18, the rubber bottom sleeve 17 and the cutting top sleeve 19 can be replaced according to the thickness of the cable to be cut;
