Movable rings 11 are fixedly connected to the inner ends of the first threaded rod 9 and the second threaded rods 10. A first positioning plate 12 is movably sleeved on the outer side of the movable ring 11 at one end of the first threaded rod 9, and a second positioning plate 13 is movably sleeved on the outer side of the movable ring 11 at one end of the second threaded rod 10. In order to facilitate the installation of the protective components, the positioning mechanism 6 is provided.

[0029] Refer to Figure 2, the first outer plate 2 and the second outer plate 3 are in opposite directions, and two adjacent second outer plates 3 are snap-connected. Pull the two second outer plates 3 outward and make the end faces at the connection of the two second outer plates 3 fit together.

[0030] Refer to Figure 3 , the take-up reel 7 and the limit ring 8 are both located inside the first outer plate 2, and both the take-up reel 7 and the limit ring 8 are movably connected to the first outer plate 2. Through the rotation of the take-up reel 7, the winding work of the protective film 4 is carried out, and the rotation of the take-up reel 7 is limited by the limit ring 8.

[0031] Refer to Figure 3 , one end of the protective film 4 is fixedly connected to the take-up reel 7, and the other end of the protective film 4 passes through one side of the first outer plate 2 and is fixedly connected to the corresponding second outer plate 3. First, the first outer plate 2 is sleeved on the outside of the cable body 1, and then the two second outer plates 3 are pulled to move along the outside of the cable body 1. At the same time, the movement of the second outer plate 3 stretches the protective film 4 to move synchronously, thereby forming a protective structure to protect the cable body 1 and reduce the damage to the cable surface.

[0032] Refer to Figure 4 , the first threaded rod 9 is threadedly connected to the first outer plate 2, the second threaded rod 10 is threadedly connected to the second outer plate 3, and the first threaded rod 9 and the second threaded rod 10 are in opposite directions.

At the same time, the movement of the second outer plate 3 stretches the protective film 4 to move synchronously. Through the cooperation of the limit ring 8 and the winding shaft 7, the stability of the winding and unwinding of the protective film 4 is ensured. The protective film 4 and the first outer plate 2 as well as the second outer plate 3 form a protective structure to protect the cable body 1 and reduce the situation of cable surface damage. Then, rotate the first threaded rod 9 and the second threaded rod 10 in sequence. Cooperating with the outer plates connected by threads, drive the corresponding movable rings 11 to move, so that both the first positioning plate 12 and the second positioning plate 13 slide inwards for adjustment.
