[0028] The following embodiments are for illustration only and can be combined with each other, and are not limited to the contents presented in the following single embodiments.

[0029] See also Figures 1 to 5 The utility model provides a cable wear-proof sheath, comprising a protective tube 1 and a limiting device 2, wherein the limiting device 2 is located at both ends of the protective tube 1; the limiting device 2 comprises a limiting plate 21, wherein the limiting plate 21 is provided with a through hole, and a connecting tube 22 is axially extended from the periphery of the through hole (the limiting plate 21 blocks the outside of the wall opening, so that the device can be stably fixed in the wall opening to prevent the device from falling during the wire pulling process), and a smooth arc surface is formed between the limiting plate 21 and the connecting tube 22 (the smooth arc surface at the connection can prevent the cable from being damaged by excessive bending at the port, and can also reduce the wear of the cable and the edge of the device, and prevent the edge from scratching the cable); the connecting tube 22 and the protective tube 1 are connected. Removable connection; the protective tube 1, the connecting tube 22 and the through hole form a through channel for the cable to pass through (the limit devices 2 at both ends of the device are detachable, which is convenient for installation in the wall. The cable passes through the device to avoid direct contact with the wall, reducing cable wear and preventing the wall from causing scratches and damage to the cable); the cable anti-wear protection device is made of insulating material (insulating material prevents accidents during cable use and increases the safety of device use); the inner walls of the protective tube 1 and the connecting tube 22 are provided with a graphite self-lubricating coating (the lubricating coating can effectively reduce the friction between the cable and the inside of the device, making it easier to pull the cable and minimizing the wear on the cable).

[0030] In this embodiment, please refer to Figure 2 , the protective tube 1 is provided with a card slot 4 at both ends, and the connecting tube 22 port is provided with a card member 3, the card slot 4 and the card member 3 cooperate with each other, and the card slot 4 is an "L"-shaped structure. The card member 3 on the connecting tube 22 is slid into the L-shaped card slot 4 and fixed, and the limit device 2 is connected to the protective tube 1 together, and disassembly and assembly are very convenient. When in use, first insert the protective tube 1 into the through hole on the wall, fix the limit device 2 at both ends of the protective tube 1 respectively, slide the card member 3 on the connecting tube 22 into the card slot 4 and fix it, so that the limit plate 21 is fixed outside the wall opening, and then the cable can be passed through the inside of the device. After use, the device can be disassembled and removed for reuse.

[0031] In this embodiment, please refer to Figure 3 The clamping slot 4 defines a connecting slot 41 along the axial direction of the edge of the protective tube 1. The clamping slot 4 defines a plurality of mutually parallel fixing slots 42 along the circumference of the protective tube 1. The connecting slots 41 communicate with the fixing slots 42. Providing multiple fixing slots 42 can accommodate different wall thicknesses and requirements. Adjusting the clamping member 3 to slide into different fixing slots 42 adjusts the position of the limiting device 2, ensuring a stable fixation to the wall and preventing the device from loosening and falling during the wire pulling process.

[0032] In this embodiment, please refer to Figure 4 The protective tube 1 is composed of several short tubes 5, which are detachably connected to each other; adjacent short tubes 5 are connected by threads. During use, the length of the short tubes 5 is connected according to the thickness of the wall. The position of the connecting tube 22 and the slot 4 securing the protective tube 1 can be adjusted. The distance between the limit plate 21 of the limit device 2 and the wall surface can be adjusted to ensure that the device is fixed in the wall opening and does not loosen when pulling the wire, achieving a better fixing effect. After use, it can be removed. The connection structure is simple and easy to operate.

[0033] In this embodiment, please refer to Figure 5 The outer wall of the connecting tube 22 is provided with an elastic threaded protrusion 6 made of a rubber material. This ensures that the retaining device 2 is firmly fixed within the wall opening, preventing it from moving when the cable is pulled. During use, the connecting tube 22 is screwed into the wall opening and connected to the protective tube 1 until the entire device is secure. When finished, the retaining device 2 is unscrewed. This allows for repeated use, providing a more secure and reliable fixation and facilitating operation.
