The wheel is equipped with a wheel axle, and the wheel is covered with an anti pulley. The anti pulley is fixedly connected to the wheel through a locking buckle. The locking buckle is provided with several and evenly distributed on the inner ring of the anti pulley, and the outer ring of the anti pulley is provided with gear teeth; The outer side of the wheel is equipped with a triangular support frame composed of telescopic rods, and at each of the three vertices of the triangular support frame, there is a driven wheel shaft arranged parallel to the wheel axis. Each driven wheel shaft is hinged with a driven wheel. The present invention utilizes the driven wheels hinged at the three vertices of the triangular support frame to enable the wheel to have better walking ability when encountering uneven ground; The use of anti slip wheels on the wheels can prevent the vehicle from slipping; Wheeled vehicles can be transformed into
