The two ends of the top of the two support frames are respectively welded to the four corners of the bottom of the support plate. Both ends of the bottom of the support plate are provided with rolling components for limiting the cable. Both ends of the bottom of the movable frame are movable through the support plate. A hydraulic cylinder is welded to the middle of the top of the support plate, and the top of the hydraulic rod of the hydraulic cylinder is welded to the middle of the top wall inside the movable frame. In this solution, when the cable is being straightened and moved, the hydraulic rod of the hydraulic cylinder applies a top force to the movable frame, so that the movable frame drives the first fixed shaft to rise, and at the same time, the first fixed shaft drives the drum to rise, applying a pulling force to the straightened and moved cable, thereby adjusting the tension of the cable.
