A first gear 22 is coaxially installed on the upper end of the winding shaft 2, and a turntable 5 and a second gear (not shown in the figure) that are concentrically fixed are vertically installed in the box body 1, and the second gear is vertically meshed with the first gear 22. When the crank 21 is turned to drive the winding shaft 2 to rotate, the turntable 5 can be driven to rotate through the vertical meshing transmission of the two gears. A lever 51 is vertically fixed to the surface of the turntable 5, and a moving assembly is provided in the box body 1 below the turntable 5 to slide up and down, a slide groove 610 is horizontally opened above the moving assembly, and the lever 51 is slidably clamped in the slide groove 610, and a pulley 64 is installed below the moving assembly. Specifically, the moving assembly includes a guide plate 61, a slide bar 63 and a slide sleeve 62. The slide sleeve 62 is fixed in the box body 1. The slide bar 63 is slidably sleeved in the slide sleeve 62. The pulley 64 is installed at the lower end of the slide bar 63. The upper end of the slide bar 63 is vertically fixed to the middle of the horizontally arranged guide plate 61. The lever 51 is slidably arranged in a slide groove 610 opened along the length direction of the guide plate 61. When the crank 21 is shaken to rotate the turntable 5, the lever 51 can slide in the slide groove 610. Under the limiting action of the slide sleeve 62, the guide plate 61 and the slide bar 63 slide up and down at a uniform speed, thereby driving the pulley 64 to slide up and down. As the winding shaft 2 rotates, the wire rope 3 is evenly wound on the winding shaft 2.
[0025] A wire hole is provided at the bottom of the box body 1, and a wire tube 11 with a trumpet-shaped design on the top is fixed at the wire hole 10 in the box body 1. The top of the wire tube 11 is open to effectively guide the wire rope 3 and reduce the friction between the wire tube 11 and the wire rope 3. The metal pendant 7 is movably arranged below the box body 1, one end of the wire rope 3 is fixedly connected to the metal pendant 7, and the other end passes through the wire hole 10, the wire tube 11, and passes around the pulley 64 before being fixedly connected to the winding shaft 2.
[0026] Two circular baffles 23 are coaxially fixed on the winding shaft 2, and the winding shaft 2 between the two baffles 23 is a winding part for winding the wire rope 3.
