[0033] In the present utility model, the cylinder 1 is provided to provide a winding force point, and in cooperation with the two limit discs 10, the tape assembly 2 above the cylinder 1 is restricted and cooperated.

[0034] Furthermore, the distance between the two limit discs 10 is adapted to the width of the tape assembly 2.

[0035] In the present utility model, the two limit discs 10 simultaneously protect and cooperate with the side of the tape assembly 2, reducing the damage effect of external touch on the tape assembly 2

[0036] Specifically, the tape assembly 2 is sequentially provided with an adhesive layer 20, an insulating layer 21, a reinforcing layer 22, a waterproof layer 23 and a wear-resistant layer 24 from bottom to top.

[0037] It should be noted that the upper surface of the adhesive layer 20 is adhesively fixed to the lower surface of the insulating layer 21, and the width of the outer wall of the adhesive layer 20 is adapted to the width of the outer wall of the insulating layer 21.

[0038] In the present utility model, the adhesive layer 20 is made of adhesive fibers, which helps to adhesively wrap and cooperate with external cables. With the cooperation of the insulating layer 21, the overall insulation performance is increased.

[0039] Furthermore, the upper surface of the insulating layer 21 is adhesively fixed to the lower surface of the strengthening layer 22, and the width of the outer wall of the insulating layer 21 is adapted to the width of the outer wall of the strengthening layer 22.

[0040] In the present utility model, the strengthening layer 22 is made of a metal wire mesh, which increases the overall toughness and avoids the influence of fracture damage during long-term use.
