This utility model has the following beneficial effects: it realizes the functions of easy installation, time saving, and extension."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] In the process of using this utility model, the first and second housings are placed around the outside of the pull wire, and the screws are tightened to connect them and complete the fixation. However, in actual use, the pull wires are of different models and sizes. When the pull wire size is smaller than the radius between the housings, this fixing method lacks stability and cannot fully fix the protective sleeve around the pull wire, causing the protective sleeve to loosen and fall off from the outside of the pull wire. Therefore, it is necessary to improve the pull wire protective sleeve with high fixing stability to solve the above problems. Utility Model Content

[0006] To overcome the problem that when the pull wire size is smaller than the radius between the housings, the housing cannot be securely fixed to the outside of the pull wire, causing the protective sleeve to loosen.

[0007] The technical solution of this utility model is as follows: a pull cable protective sleeve with high fixation stability, including a first connecting shell, a first outer shell and a limiting mechanism, a second connecting shell rotatably connected inside the first connecting shell, a limiting mechanism provided inside the first connecting shell and the second connecting shell, a first outer shell provided inside the first connecting shell, a second outer shell provided inside the second connecting shell, the second outer shell rotatably connected inside the first outer shell, a clamping block slidably connected inside the first outer shell and the second outer shell, an anti-slip pad fixedly connected to the inner side of the clamping block, the protective sleeve is stably fixed to the outside of the pull cable by sliding the clamping block and by the anti-slip pad.

[0008] Preferably, both the first and second outer shells have grooves at the relative positions of the clamping blocks, and the clamping blocks are slidably connected inside the grooves.

[0009] Preferably, the first and second housings are rotatably connected to a threaded rod inside, the clamping block is threaded to the outside of the threaded rod, a knob is fixedly connected to the outside of the threaded rod, a first fixing buckle is fixedly connected to the top of the second housing, a second fixing buckle is fixedly connected to the top of the first housing, a pressure plate is rotatably connected inside the first fixing buckle, a first spring is fixedly connected between the pressure plate and the first fixing buckle, and a rotating groove is opened at the relative position of the threaded rod in the first and second housings, with the threaded rod rotatably connected inside the rotating groove.

[0010] Preferably, the first outer shell and the second outer shell are provided with a rotating groove at the relative position of the threaded rod, and the threaded rod is rotatably connected inside the rotating groove.

[0011] Preferably, the limiting mechanism includes a sliding block, which is slidably connected inside the first connecting shell and the second connecting shell, and fixedly connected outside the first outer shell and the second outer shell. A first fixing rod is fixedly connected to the outer side of the sliding block, and a connecting plate is fixedly connected to the outer side of the first fixing rod. A limiting rod is slidably connected inside the connecting plate, and the limiting rod is snapped into the inner side of the first connecting shell and the second connecting shell. A pull plate is fixedly connected to the outer side of the limiting rod, and an outer ring is fixedly connected to the outer side of the limiting rod. A second spring is fixedly connected between the outer ring and the connecting plate.

[0012] Preferably, the first connecting shell and the second connecting shell are provided with grooves at the relative positions of the sliding block, and the sliding block is slidably connected inside the grooves.

[0013] Preferably, both the first connecting shell and the second connecting shell have slots at the relative positions of the limiting rods, and the limiting rods are engaged and connected inside the slots.

[0014] The beneficial effects of this utility model are as follows: For relatively small pull cords, it is not possible to securely fix the protective sleeve to its outside. By adding clamping blocks and anti-slip pads, the distance between the clamping blocks and the anti-slip pads can be adjusted by sliding the clamping blocks to ensure sufficient contact between the clamping blocks and the anti-slip pads, thus fixing the protective sleeve to the outside of the pull cord. This avoids the problem that when the pull cord size is smaller than the radius between the shells, the shell cannot be securely fixed to the outside of the pull cord, resulting in the protective sleeve becoming loose.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figure 1 - Figure 6This utility model provides an embodiment of a high-stability cable protection sleeve, including a first connecting shell 1, a first outer shell 21, and a limiting mechanism. A second connecting shell 4 is rotatably connected inside the first connecting shell 1. Limit mechanisms are provided inside both the first and second connecting shells 1 and 4. The first outer shell 21 is located inside the first connecting shell 1, and a second outer shell 22 is located inside the second connecting shell 4. The second outer shell 22 is rotatably connected inside the first outer shell 21. A clamping block 23 is slidably connected inside the first and second outer shells 22. An anti-slip pad 24 is fixedly connected to the inner side of the clamping block 23. The protective sleeve is securely fixed to the outside of the cable by sliding the clamping block 23 and using the anti-slip pad 24. In use, the first outer shell 21 and the second outer shell 22 are placed over the cable to be protected. After external contact, rotate the first outer shell 21 to close the first outer shell 21 and the second outer shell 22. According to the diameter of the pull wire to be protected, slide the clamping block 23 to adjust the distance between the clamping blocks 23. Then, the anti-slip pad 24 contacts the outer periphery of the pull wire to fully fix the protective sleeve. Then, according to the length of the pull wire to be protected, pull the first outer shell 21 and the second outer shell 22 outward. Then, limit the position of the first outer shell 21 and the second outer shell 22 after sliding by the limiting mechanism. The first outer shell 21 and the second outer shell 22 both have a sliding groove at the relative position of the clamping block 23. The clamping block 23 is slidably connected inside the sliding groove. The sliding groove limits the sliding of the clamping block 23, so that the clamping block 23 slides linearly inside the first outer shell 21 and the second outer shell 22, preventing the clamping block 23 from shifting and affecting the clamping of the pull wire by the anti-slip pad 24.

[0024] Please see Figure 1 - Figure 4 In this embodiment, a threaded rod 25 is rotatably connected inside the first outer shell 21 and the second outer shell 22. A clamping block 23 is threadedly connected to the outside of the threaded rod 25. A knob 26 is fixedly connected to the outside of the threaded rod 25. A first fixing buckle 27 is fixedly connected to the top of the second outer shell 22, and a second fixing buckle 28 is fixedly connected to the top of the first outer shell 21. A pressure plate 29 is rotatably connected inside the first fixing buckle 27. A first spring 210 is fixedly connected between the pressure plate 29 and the first fixing buckle 27. A slot is provided at the relative position of the threaded rod 25. The threaded rod 25 is rotatably connected inside the slot. The first spring 210 provides a pushing force to the pressure plate 29, so that the pressure plate 29 is more firmly in contact with the second fixing buckle 28, thereby restricting the first outer shell 21 and the second outer shell 22 after closing to prevent them from opening. The first outer shell 21 and the second outer shell 22 have slots at the relative position of the threaded rod 25. The threaded rod 25 is rotatably connected inside the slot. The rotation of the threaded rod 25 is restricted by the slot, preventing the threaded rod 25 from moving with the clamping block 23.

[0025] Please see Figure 1 , Figure 5 - Figure 6In this embodiment, the limiting mechanism includes a sliding block 31, which is slidably connected inside the first connecting shell 1 and the second connecting shell 4. The sliding block 31 is also fixedly connected outside the first outer shell 21 and the second outer shell 22. A first fixing rod 32 is fixedly connected to the outer side of the sliding block 31, and a connecting plate 33 is fixedly connected to the outer side of the first fixing rod 32. A limiting rod 34 is slidably connected inside the connecting plate 33, and the limiting rod 34 is snapped into the interior of the first connecting shell 1 and the second connecting shell 4. A pull plate 35 is fixedly connected to the outer side of the limiting rod 34, and an outer ring 36 is fixedly connected to the outer side of the limiting rod 34. A second spring 37 is fixedly connected between the outer ring 36 and the connecting plate 33. The second spring 37 provides a pushing force to the outer ring 36, pulling the pull plate 35 to adjust the sliding distance between the first outer shell 21 and the second outer shell 22. After the movement, releasing the pull plate 35 causes the limiting rod 34 to automatically spring back to its original position, while simultaneously allowing the limiting rod 34 to better engage inside the first connecting shell 1 and the second connecting shell 4. The first connecting shell 1 and the second connecting shell 4 have grooves at the relative positions of the sliding block 31. The sliding block 31 is slidably connected inside the grooves, which limit the sliding range of the sliding block 31 and prevent the first outer shell 21 and the second outer shell 22 from sliding out too much, causing them to detach from the first connecting shell 1 and the second connecting shell 4. The first connecting shell 1 and the second connecting shell 4 both have slots at the relative positions of the limiting rod 34, and the limiting rod 34 is engaged inside the slots. Through the cooperation of the slots and the limiting rod 34, the positions of the first outer shell 21 and the second outer shell 22 after sliding are fixed, preventing the first outer shell 21 and the second outer shell 22 from moving again.

[0026] During operation, pull the pull plate 35 according to the length of the cable to be protected. After the limiting rod 34 disengages from the slot inside the first connecting shell 1 and the second connecting shell 4, pull the first outer shell 21 and the second outer shell 22 to slide, adjusting the overall length of the protective sleeve. After the first outer shell 21 and the second outer shell 22 move to the appropriate position, release the pull plate 35. The second spring 37 provides a pushing force to the outer ring 36, pushing the outer ring 36 and the limiting rod 34 back to their original position. Then, the limiting rod 34 re-engages with the slot, thereby restricting the position of the first outer shell 21 and the second outer shell 22. Finally, press the pressure plate 29 to disengage it from the second fixing buckle 28, opening the protective sleeve. After the first outer shell 21 and the second outer shell 22 are placed over the pull cable to be protected and closed, the pressure plate 29 is released and the first spring 210 provides a pushing force to it, causing it to return to its original position and re-contact with the second fixing buckle 28, preventing the first outer shell 21 and the second outer shell 22 from opening again. According to the size of the pull cable, the knobs 26 on both sides are rotated, causing the threaded rod 25 to rotate and drive the clamping block 23 to slide inside the first outer shell 21 and the second outer shell 22. It then contacts the pull cable through the anti-slip pad 24, increasing the friction between the protective cover and the pull cable to prevent the entire protective cover from sliding, so that the entire protective cover is firmly fixed to the outside of the pull cable, thus protecting the pull cable and completing the fixation.

[0027] By adding clamping block 23 and anti-slip pad 24 through the above steps, the problem of the protective cover not being able to be firmly fixed to the outside of the pull wire when the pull wire size is smaller than the radius between the housings is solved.
