[0029] Reference Figure 1 , Figure 3 As shown, the top of the fixed platform 1 away from the support platform 2 side has a groove, and the center of the groove is installed with the drive motor 101, the drive motor 101 is provided with the drive shaft 102 penetrating the inside of the fixed platform 1, and the side wall of the fixed platform 1 is vertically provided with a rectangular groove corresponding to the sliding block 203. The universal wheel 302 outside the bottom plate 3 is convenient to push the bottom plate 3 to the position close to the fixed platform 1, so that the two sliding blocks 203 and the rectangular groove of the side wall of the fixed platform 1 correspond to each other. At this time, the electric push rod 301 can be easily started, so that the support platform 2 can be driven to move to the top, so that one end of the support platform 2 slides along the rectangular groove of the side of the fixed platform 1 to the top through the sliding block 203.
