[0024] The implementation principle of a cable retractor for coal mines according to an embodiment of this application is as follows: First, the retractor is transported to a predetermined position at the coal mine work site. Each support rod extends downward through the through hole in the base plate. Since one end of the support rod has a pointed tip, it can be easily inserted into the ground. Pressing the balloon inflates the air bladder, and the air bladder gradually expands to further compress the support rod, increasing the stability of the retractor. Turning the handle drives the rotating shaft to rotate. The gear on the rotating shaft meshes with the rack at one end of the moving rod, thereby moving the moving rod in the horizontal groove. The moving rod pushes the stop bar in the vertical groove to move. The stop block on the stop bar moves through the short groove in the through hole and then presses the support rod against the inner wall of the through hole, thus fixing the position of the support rod.

[0025] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
