The cable surface is in close contact, and then the protective tube 1 is supported, and the stabilizing ring 5 is screwed into the two ends of the protective tube 1 from both ends; on the one hand, after the stabilizing ring 5 is screwed in: the inner wall of the stabilizing ring 5 is in compression contact with the outer walls of the two ends of the protective pad 3, and the outer wall of the stabilizing ring 5 is threadedly connected with the inner sides of the two ends of the two protective plates 2, thereby improving the stability of the detachable protective tube 1 during use, and avoiding the detachable protective tube 1 from loosening and falling off during the process of pulling the cable back and forth, so as to improve the effectiveness of the long-term use of the protective joint; on the other hand, in the process of screwing in the stabilizing ring 5: the stabilizing ring 5 pushes the extrusion component 4 inward, so that the other end of the extrusion component 4 squeezes the protective pad 3 from the periphery to the copper wire connection position, and the middle position of the protective pad 3 squeezes the copper wire connection position to improve the stability of the copper wire connection, so as to further avoid the loosening or loosening of the connection position during the cable pulling process; thereby, through the above-mentioned detachable protective tube 1, the protective pad 3 and the stabilizing ring 5, it is convenient to repair or reconnect the joint after direct disassembly, and can effectively improve the stability of the cable joint connection and the anti-loosening and anti-loosening effects.

[0031] In the present invention, the extrusion assembly 4 is provided with a pressing plate 401 fixed to the outer side of the protective pad 3, the pressing plate 401 is arranged in the middle area of ​​the axis of the protective tube 1, a connecting frame 402 is installed in the middle position of the outer side of the pressing plate 401, the connecting frame 402 is rotatably connected to a connecting shaft 403 by a latch, and the end of the connecting shaft 403 away from the connecting frame 402 is rotatably connected to a connecting frame 2 404 by a latch, the connecting frame 2 404 is in sliding contact with the inner side of the guard plate 2, the connecting frame 2 404 is arranged at the end position of the guard plate 2 close to the thread groove 203, a slide groove 204 is provided at a position where the inner wall of the guard plate 2 and the connecting frame 2 404 are adapted, a slide groove 205 is provided in the slide groove 204, the width of the slide groove 205 is greater than the width of the slide groove 204, and the connecting frame 204 is provided with a connecting groove 205.

The slider 406 slides within the slide groove 205 in a limited position. Therefore, when not installed, the protective pad 3 naturally stretches and pushes the outer pressure plate 401, the connecting frame 402 and the connecting shaft 403 outward, so that the connecting frame 404 is in an end position close to the protective plate 2; when installed and used, the stabilizing rings 5 ​​at both ends will push the connecting frame 404 inward during the process of being screwed in, thereby tilting the connecting shaft 403, and the connecting frame 402 and the pressure plate 401 squeeze the protective pad 3 towards the middle position of the copper wire connection, so as to improve the limiting and stabilizing effect of the copper wire connection position.

[0032] In the present invention, two groups of extrusion components 4 are arranged on the guard plate 2, and the two groups of extrusion components 4 are respectively arranged at the two end positions of the guard plate 2.
