In specific operation, before cutting the cable insulation layer, first use a straightener or manually twist to adjust one end of the cable to be cut to a straight state. When cutting the cable insulation layer, first control the third electric telescopic rod 22 to extend or retract and reset, and the baffle 23 can be controlled to be horizontal By moving the baffle plate 23 in a straight line, the vertical distance between the baffle plate 23 and the stainless steel cutting knife 17 can be adjusted. By observing the scale value on the measuring ruler 25 pointed by the pointer 24, the vertical distance between the baffle plate 23 and the stainless steel cutting knife 17 (i.e., the length of the insulation layer of the cable to be cut and stripped) can be observed. After the position of the baffle plate 23 is adjusted, the head of the end of the cable to be cut is passed through the two arc-shaped clamping plates 5 and the two stainless steel cutting knives 17 from right to left in sequence and abutted against the right side wall of the baffle plate 23, and then the two first electric telescopic rods 4 are controlled to extend and operate, so that the two arc-shaped clamping plates 5 gradually approach each other, and the cooperation of the two arc-shaped clamping plates 5 and the two anti-slip pads 6 is utilized. When used, the cable can be clamped firmly and stably. By turning on the two electric heating plates 16, the corresponding stainless steel cutting knives 17 can be heated respectively. Then, by controlling the extension of the two second electric telescopic rods 14, the two stainless steel cutting knives 17 gradually approach each other until the two stainless steel cutting knives 17 cut through the insulation layer at the top of the cable and the insulation layer at the bottom of the cable respectively. Then, the motor 19 is controlled to rotate forward or reverse, and the motor 19 drives the gear 20 to rotate. The gear 20 drives the outer gear ring 21, the annular sleeve 11, the two second electric telescopic rods 14, the two mounting plates 15, the two electric heating plates 16 and the two stainless steel cutting knives 17 to rotate, so as to cut around the insulation layer of the cable. The insulating layer of the cable can be cut off, and by using the stainless steel cutting knife 17 with heat, the insulating layer of the cable can be cut open and cut through more easily, keeping the incision neat. After the insulating layer is cut off, the motor 19 is stopped, and then the electric slide 8 is controlled to move linearly to the left on the electric guide rail 7, so that the electric slide 8 can drive the movable seat 9, the annular sleeve 11, the guide ring 12, the cutting assembly, the rotating drive assembly and the cutting length limiting assembly to move linearly to the left. The two stainless steel cutting knives 17 are used to jointly apply a horizontal leftward thrust to the insulating layer, so that the cut insulating layer on the cable can be pushed to gradually slide out of the cable core of the cable, thereby achieving the cutting and stripping effect of the cable insulating layer.
