Take the body 1 moving along the first direction as an example. However, in other embodiments of the present invention, the counterclockwise rotation of the reversing wheel 53 can also cause the second traveling wheel set 4 to be lifted away from the track along with the movement of the reversing seat 31, thereby allowing the first driving assembly 21 to drive the vehicle. Body 1 moves in the first direction. That is, as long as the two different rotation directions of the rotating wheel 53 are reversed, the second traveling wheel set 4 can be lifted away from the track or released to contact the track as the reversing seat 31 moves. .
