The first motor 301 is installed The output shaft is connected to one end of the first threaded rod 302 outside the base 1. When the first motor 301 works and drives the first threaded rod 302 to rotate clockwise, the two movable plates 303 located on the first threaded rod 302 move to the left side inside the base 1 along the first guide rod 304 at the same time, thereby driving the two movable blocks 305 located on the movable plate 303 to move to the left side synchronously. Since the movable rod 307 cannot move left and right, the movable rod 307 moves upward along the sliding groove 306 while the movable block 305 moves to the left. At this time, the walking wheel 2 moves upward accordingly until the walking wheel 2 completely moves into the accommodating groove 10, and the first motor 301 stops moving.
