Then, the ring 25 is rotated so that the ring 25 moves on the outer surface of the sleeve 21 towards the groove ring 22. The inner wall of the pressing ring 26 presses against the surface of the pressing piece 27 and gradually contacts the thicker end of the pressing piece 27 to press the pressing piece 27 tightly against the outer surface of the groove ring 22, further tightening the connection between the threaded cylinder 24 and the groove ring 22 and the position of the protection cylinder 23 and the sleeve 21 on the outer surface of the wire body 1. After the protection device 2 is installed, the slider 32 is pushed to slide on the inner wall of the groove block 31, and the bottom end of the slider 32 is abutted against the ground or the wall. Then, the threaded ring 34 is rotated so that the threaded ring 34 moves on the outer surface of the screw 33 towards the groove block 31, and the side of the threaded ring 34 provided with the rubber gasket 35 is pressed against one side of the groove block 31 to fix the position of the slider 32, and the lower part of the protection cylinder 23 is supported by the slider 32.
