When the support plate 313 moves upward, it drives the sliding bar 3111 to slide upward in the sliding bar tube 316. When the sliding bar 3111 rises, the connecting spring 3113 props up the rubber pad 3114 through elastic force, and when the rubber pad 3114 is propped up, it drives the connecting rod 3112 to rise. When the support plate 313 moves upward, the sling is propped up by the shackle fixing frame 315, and then the rope is placed on the placing inclined plate 413. During the upward movement of the support plate 313, the placing inclined plate 413 is driven to move by the fixing block 4111. During the movement of the placing inclined plate 413, it slides on the slide rail 416 through the rolling pulley 418. When the placing inclined plate 413 rises with the support plate 313, it will be placed and protected by the supporting fixing plate 414 and the rotating sliding bar 415.
