The anti pulley of the track chassis is fixedly connected to the wheel through a locking buckle, which is provided with several locking buckles evenly distributed on the inner ring of the anti pulley. The outer ring of the anti pulley is provided with gear teeth, and the track is provided with through holes that cooperate with the gear teeth; The outer side of the wheel is equipped with a triangular support frame composed of telescopic rods. At the three vertices of the triangular support frame, there is a driven wheel axle arranged parallel to the wheel axis. Each driven wheel axle is hinged with a driven wheel. The three driven wheels and anti-skid wheels are all arranged on the track by internal cutting.
