[0020] Compared with the prior art, the advantages of the present invention are:

[0021] (1) In this scheme, when it is necessary to protect the tap of the supporting core rope, the user holds the handle and rotates the handle. The rotation of the handle drives the rotating rod to rotate. The rotation of the rotating rod pulls the connecting rope to wrap around the surface of the rotating rod. The winding of the connecting rope pulls the two horizontal plates to move inward at the same time. The movement of the horizontal plate compresses the spring. Then, the movement of the horizontal plate pulls the two connecting rods and the two positioning plates to move inward. At this time, the protective sleeve can be placed on the surface of the cold shrink sleeve body. Then, the handle is released. The spring is reset by its own elasticity to push the two horizontal plates, the two connecting rods and the two positioning plates to move outward. The two positioning plates are clamped in the supporting core rope by the elastic action of the two springs, thereby facilitating the positioning of the tap of the supporting core rope and protecting the tap of the supporting core rope.

[0037] In this embodiment, the positioning mechanism includes a positioning component and a guide component. The positioning component and the guide component are both arranged in the cold shrink sleeve body 1, and the positioning component and the guide component are connected.

[0038] Specifically, the positioning assembly includes a transverse plate 7, a spring 9, a connecting rod 10 and a positioning plate 11. The transverse plate 7, the spring 9, the connecting rod 10 and the positioning plate 11 are all provided in two. The two transverse plates 7 are both provided in the mounting groove 4. The two springs 9 are both fixedly connected between the two transverse plates 7. The two connecting rods 10 are respectively fixedly connected to the outer sides of the two transverse plates 7, and the two connecting rods 10 are both movable through the fixed seat 3. The two positioning plates 11 are respectively fixedly connected to the outer sides of the two connecting rods 10, and the two positioning plates 11 are both connected to the supporting core rope 2.

[0039] In this embodiment, the spring 9 fixes the position of the cross plate 7 through its own elastic action, fixes the connecting rod 10 and the positioning plate 11 through the fixation of the cross plate 7, and clamps the two positioning plates 11 in the supporting core rope 2 through the elastic action of the two springs 9, thereby facilitating the positioning of the tap of the supporting core rope 2, thereby protecting the tap of the supporting core rope 2.

[0046] Working principle: when it is necessary to protect the tap of the supporting core rope 2, hold the turning handle 14 and turn the turning handle 14. The turning of the turning handle 14 drives the turning rod 12 to rotate. The turning rod 12 pulls the connecting rope 13 to wrap around the surface of the turning rod 12. The winding of the connecting rope 13 pulls the two cross plates 7 to move inward at the same time. The movement of the cross plate 7 compresses the spring 9, and then the movement of the cross plate 7 pulls the two connecting rods 10 and the two positioning plates 11 to move inward. At this time, the protective cover 5 can be sleeved on the surface of the cold shrink sleeve body 1, and then the turning handle 14 is released. The spring 9 resets itself elastically to push the two cross plates 7, the two connecting rods 10 and the two positioning plates 11 to move outward, so that the two positioning plates 11 are clamped in the supporting core rope 2 through the elastic action of the two springs 9, so as to facilitate the positioning of the tap of the supporting core rope 2, thereby protecting the tap of the supporting core rope 2.
