The sliding cylinder 14 is fixedly connected to the rotating shaft 16. After the conductor 2 is electrically connected to the power equipment, the conductor 2 will follow the power equipment to move and flip during the process. It is necessary to make the sliding cylinder 14 flip along with the movement of the conductor 2, so that the rotating shaft 16 rotates on the rotating seat 15. During the rotation of the rotating shaft 16, the spring spring 17 is tightened. When the conductor 2 is reset in the bucket-shaped sleeve 4, the spring spring 17 drives the rotating shaft 16 and the sliding cylinder 14 to reset;

[0040] The rotary reset member is connected to a sliding cylinder 14, and a conductor fixing member is provided on the stretching section 5 of the conductor 2.

[0045] Working principle of this torsion-resistant cable:

[0046] First, one end area of ​​the outer layer 1 is peeled off to expose multiple conductors 2 to form a stretching section 5, and then the conductor 2 is inserted into the bucket-shaped sleeve 4, so that the conductor 2 passes through the sliding ring 25, the elastic ring sleeve 18 and the rotating ring 28 in sequence and then extends out of the bucket-shaped sleeve 4, and then the nut 35 is rotated to move on the fixing screw 34 to reduce the distance between the fixing plate 20 and the moving plate 21, so that the elastic ring sleeve 18 and the shrink ring sleeve 19 apply a clamping force to the surface of the conductor 2, so that the elastic ring sleeve 18 is connected to the conductor 2, and the fastening ring sleeve 3 is moved to the end face of the outer layer 1, and the stretching belt 8 is pulled in the inclined direction. The outer wall of the outer layer 1 is tightened circumferentially by the tightening belt 7, and after the tightening belt 7 is closely fitted with the outer layer 1, the stretching belt 8 will also stop moving in the inclined opening 11. After the stretching belt 8 stops moving, the elastic clip 10 extends into one of the slope grooves 9 of the stretching belt 8, and the stretching belt 8 remains fixed in the inclined opening 11, so that the tightening belt 7 is closely fitted with the outer layer 1, and then the pushing screw 32 is rotated to make the pushing screw 32 move laterally in the threaded sleeve 33, so that the pushing screw 32 drives the pushing block 12 to fit with the tightening belt 7;

[0047] When the conductor 2 moves with the electric equipment, the conductor 2, the elastic ring sleeve 18, the shrink ring sleeve 19, the rotating shaft 24 and the connecting rod 23 move with the conductor 2, which will drive the sliding rod 22 and the connecting rod 23 to slide in the sliding cylinder 14, so as to adapt to the distance difference between the sliding cylinder 14 and the elastic ring sleeve 18 during the movement of the conductor 2. When the conductor 2 is transported over a long distance, the connecting rod 23 is completely moved out from the internal range of the sliding cylinder 14, and then the conductor 2 is continued to be pulled by the electric equipment, so that the connecting rod 23 flips on the sliding rod 22 along the rotating seat, and the conductor 2 drives the rotating ring 28 to move in the through slide groove 27, thereby increasing the moving distance of the conductor 2 in the bucket-shaped sleeve 4. When the conductor 2 is reset, the clockwork spring 17 and the spring damper 31 will reset the sliding cylinder 14 and the rotating ring 28.
