Through the rotation of the threaded rods 23, the working platform 3 can be driven to move upward under the cooperation between the sliding plate 24, the hinged rod group 26, the concave rod 1 25 and the concave rod 21, until the working platform 3 moves upward to a suitable working height, and then the worm 46 can be driven to rotate under the action of the L-shaped toothed plate 6 and the gear 48 in the process of driving the working platform 3 to move upward, and the worm 46 and the worm wheel 45 can be driven to rotate. The meshing transmission can drive the rotating rod 43 to rotate. Through the rotation of the rotating rod 43, the protective plate 41 can be driven to rotate 180° around the rotating rod 43 under the action of the set L-shaped connecting plate 42.
