[0023] Specifically, the auxiliary fastening structure 4 includes a support seat 41, a rocker 42, a mounting frame 43, a fixing frame 44, a spring 45, and a hook 47. Two support seats 41 are mirror-mounted on the counterweight block 10 below the mounting groove 3. Each support seat 41 is rotatably connected to a rocker 42, and the rocker 42 is also rotatably connected to a mounting frame 43. A slide groove 46 is provided in the mounting frame 43, and a fixing frame 44 is slidably connected in the slide groove 46.
