[0036] Please see the drawing in the specification Figure 1 、 Figure 2 and Figure 4 The outside of sliding rod 10 is slidably sleeved with sliding clamping block 8, sliding clamping block 8 is located between fixed clamping block 3 and support block 9, the inside of fixed clamping block 3 is connected with sliding cutter holder 5, and the top and bottom of sliding cutter holder 5 are provided with sliding strips, and the top and bottom of the inner cavity of fixed clamping block 3 are provided with sliding grooves matched with the sliding strips. When sliding cutter holder 5 moves, the sliding strips slide along the sliding grooves, and then sliding cutter holder 5 can be positioned, so that sliding cutter holder 5 is more stable when moving.

[0037] Please see the drawing in the specification Figure 1 、 Figure 2 and Figure 4The left side of the sliding knife seat 5 is screwed with the first adjusting handle 1, the right side of the sliding knife seat 5 is provided with a bearing 6, the inside of the bearing 6 is installed with a rotating knife head 7, the rotating knife head 7 is provided with a scale size.

[0038] Please refer to the drawings in the specification Figure 1 and Figure 3 The side of the sliding clamp block 8 away from the fixed clamp block 3 is screwed with the second adjusting handle 12, the outer sides of the fixed clamp block 3 and the support block 9 are screwed with fastening nuts 13, the surfaces of the fixed clamp block 3 and the support block 9 are provided with thread holes matched with the fastening nuts 13. When the first adjusting handle 1 and the second adjusting handle 12 are adjusted in place, the fastening nuts 13 are screwed in to fix the first adjusting handle 1 and the second adjusting handle 12, preventing the first adjusting handle 1 and the second adjusting handle 12 from rotating, and at the same time, the fixed clamp block 3 is provided with fastening nuts 13 at the corresponding parts of the sliding knife seat 5, preventing the sliding knife seat 5 from shaking and affecting normal cutting during cutting.

[0041] Working principle: in use, the operator rotates the first adjusting handle 1, because the first adjusting handle 1 and the sliding knife holder 5 are threadedly connected, the first adjusting handle 1 drives the sliding knife holder 5 to move left until the rotary cutter head 7 is retracted to the innermost side, and at the same time, the second adjusting handle 12 is rotated, because the second adjusting handle 12 is threadedly connected with the sliding clamp block 8, and the sliding clamp block 8 is sleeved on the outside of the sliding rod 10, when the second adjusting handle 12 is rotated, it drives the sliding clamp block 8 to move left, so that the distance between the fixed clamp block 3 and the sliding clamp block 8 is consistent with the outer diameter of the stripped cable, then the wire stripping support tool is sleeved into the cable to the position where stripping is required.

[0042] Then the operator continues to rotate the second adjusting handle 12, so that the universal rollers 4 on the fixed clamp block 3 and the sliding clamp block 8 press the cable, and then the tightening nuts 13 on the supporting block 9 are locked, in order to make the universal rollers 4 better adhere to the cable, the position of the universal rollers 4 on the fixed clamp block 3 can be adjusted according to the diameter of the cable, then the first adjusting handle 1 is reversely rotated, so that the rotary cutter head 7 is gradually rotated out, when the rotary cutter head 7 contacts the cable insulation, the wire stripping support is circularly rotated in the same direction, so that the cutting edge of the rotary cutter head 7 is turned to the circular direction of the cable, then the first adjusting handle 1 and the sliding knife holder 5 are fixed by gradually and slowly rotating the first adjusting handle 1 again, so that the cutting edge of the rotary cutter head 7 penetrates into the cable insulation layer to the corresponding depth position, and then the two tightening nuts 13 on the fixed clamp block 3 are locked.

[0043] Then the operator holds the first adjusting handle 1 and the second adjusting handle 12 to circularly rotate the wire stripping support, so that the circular cutting of the cable insulation layer is completed, when the insulation layer is thick, the first adjusting handle 1 can be rotated to gradually and layer by layer change the penetration depth of the rotary cutter head 7 to complete the cutting work, in the process of penetration, the scale position on the rotary cutter head 7 needs to be observed to understand the penetration depth of the insulation layer, so as to avoid damage to the electric core due to operation error.

[0044] After the circular cutting is completed, the two tightening nuts 13 on the fixed clamp block 3 are loosened, and the first adjusting handle 1 is rotated, so that the rotary cutter head 7 is gradually withdrawn from the cable insulation layer, when the rotary cutter head 7 is withdrawn to contact the outer skin of the cable insulation layer, the first adjusting handle 1 and the second adjusting handle 12 are held to longitudinally push the wire stripping support in the same direction, so that the cutting edge of the rotary cutter head 7 is turned to the longitudinal direction of the cable, and the two tightening nuts 13 on the fixed clamp block 3 are locked.

[0045] The first adjusting handle 1 and the second adjusting handle 12 are held to longitudinally push the wire stripping support, so that the longitudinal cutting of the cable insulation layer is completed, when the insulation layer is thick, the first adjusting handle 1 can be gradually rotated to change the penetration depth of the rotary cutter head 7 layer by layer, through the reciprocating pushing and pulling action, the rotary cutter head 7 can effectively complete the cutting work.

[0046] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, so that: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
