Through the setting of the spring 8, the end piece 7 can be connected and used.

[0026] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5, a winding mechanism 10 is provided on the cable bridge 1, and the winding mechanism 10 includes a rotating shaft 101. The horizontal part of the cable bridge 1 is installed with the rotating shaft 101 through a bearing. The upper end of the rotating shaft 101 is fixedly connected with a winding wheel 102, and the winding wheel 102 is rotatably connected to the horizontal part of the cable bridge 1. The surface of the winding wheel 102 is provided with a cable body 103. The lower rotating disk of the winding wheel 102 is provided with a socket 104. The horizontal part of the cable bridge 1 is slidably connected with an insertion rod 105, and the insertion rod 105 is slidably connected to the socket 104. The horizontal part of the cable bridge 1 is fixedly connected to the left side of the rotating shaft 101. There is a guide frame 106, the upper horizontal part of the guide frame 106 is slidably connected to the insertion rod 105, the upper horizontal part of the guide frame 106 is fixedly connected to the limit ring 107, the limit ring 107 is slidably connected to the insertion rod 105, and the lower horizontal part of the guide frame 106 is welded with a spring 2 108, and the other end of the spring 2 108 is welded to the insertion rod 105.

Under the action of the lower horizontal part of the guide frame 106, the spring 2 108 is deformed, and finally the insertion rod 105 is disengaged from the insertion hole 104, and then the handle 110 is pushed to rotate, thereby driving the rotating plate 109 to rotate, and finally driving the rotating shaft 101 to rotate. When the rotating shaft 101 rotates, it can drive the winding wheel 102 to rotate, and the cable body 103 is wound and arranged for use, avoiding the problem of the cable body 103 being entangled and scattered. Then the insertion rod 105 is released to allow the spring 2 108 to recover its deformation, so as to push the insertion rod 105 to insert into the insertion hole 104, limit the winding wheel 102, and avoid the problem of the winding wheel 102 rotating.
