Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-4 , an embodiment provided by the present utility model:

[0025] A cable resistant to bending and wear, comprising a filling block 1, a connecting copper wire 2 and a connecting nut 3. The connecting copper wire 2 is arranged inside the filling block 1, and the connecting nut 3 is arranged above the connecting copper wire 2. An insulating tube 4 is fixedly connected inside the filling block 1. A bending tube 402 is fixedly connected inside the insulating tube 4. A movable block 403 is fixedly connected inside the insulating tube 4. A fixed wire 404 is fixedly connected inside the insulating tube 4. A bending spring 405 is fixedly connected inside the bending tube 402. A friction block 5 is fixedly connected to the outside of the filling block 1, and a friction spring 503 is fixedly connected behind the friction block 5.

[0026] Further, a connecting piece 401 is fixedly connected below the connecting copper wire 2. The bending tube 402 is fixedly connected below the connecting piece 401. The movable block 403 is fixedly connected below the bending tube 402. The fixed wire 404 is fixedly connected below the movable block 403. Through the connection of the connecting piece 401, the bending tube 402, the movable block 403 and the fixed wire 404, the power supply can pass through this cable.

[0027] Further, a bending spring 405 is fixedly connected below the connecting piece 401. The fixed wire 404 is fixedly connected inside the connecting piece 401. The bending spring 405 is fixedly connected below the connecting piece 401. A conductive liquid 406 is filled inside the bending tube 402. A movable ball 407 is fixedly connected below the fixed wire 404. The outside of the movable ball 407 is movably connected to the movable block 403. A connecting ring 408 is fixedly connected above the movable block 403. By driving the connecting piece 401 and the movable block 403 through the bending spring 405, when the connecting tube 102 is bent, the bending spring 405 can straighten the connecting tube 102. By filling the inner wall of the bending tube 402 with the conductive liquid 406, the resistance change can be reduced when the connecting piece 401 and the movable block 403 are bent.

[0028] Further, a driving ring 501 is fixedly connected to the outside of the friction block 5. A movable outer shell 502 is fixedly connected behind the friction block 5. A friction spring 503 is fixedly connected inside the movable outer shell 502. A fixed column 504 is fixedly connected behind the movable outer shell 502. A connecting tube 102 is fixedly connected behind the fixed column 504. By pushing the friction block 5 through the friction spring 503, the friction item can be pushed away from the connecting tube 102.

[0029] Working principle: During the use of this device, first, loosen the connecting bolt 301 by rotating it, wind the wire around the outside of the connecting bolt 301, and fix the wire by rotating the connecting nut 3. When the connecting pipe 102 is bent, the anti-tensile pipe 101 is driven to bend by the bending of the connecting pipe 102. The anti-tensile pipe 101 drives the filling block 1 to bend. The filling block 1 drives the insulating pipe 4 to bend. The insulating pipe 4 drives the fixed wire 404 to bend. The bending of the fixed wire 404 drives the movable block 403 and the movable ball 407 to move. The entire cable is bent through the movement of the movable block 403 and the movable ball 407. The elastic force of the bending spring 405 pushes the connecting piece 401 and the connecting ring 408 to straighten the entire wire. By filling the conductive liquid 406 inside the bending pipe 402, it is prevented that the resistance changes due to activities. When the connecting pipe 102 is worn, the elastic force of the friction spring 503 pushes the friction block 5 to resist friction, and the connecting pipe 102 is offset by driving through the driving ring 501.
