The reinforcing cover 8 is welded to the outer side of the end of the external pipe 1, and one end of the inner wall of the reinforcing cover 8 is threaded. The reinforcing cover 8 is rotatably connected to the outer wall of the protective pipe 5 through the thread. A connecting assembly 9 is provided on the inner side of the reinforcing cover 8. The connecting assembly 9 includes a hollow block 901, a movable part 902, a fixed rod 903, a return spring 904, and a locking block 905.
