When in use, the power is turned on, and the second screw rod (302) is driven to rotate by means of the servo motor (301), and the second screw rod (302) cooperates with the threaded hole on the first support frame, and the limiting rod (305) and the second support frame are moved by means of the limiting hole (304), so that the spacing between the two groups of support frames (1) can be adjusted, so that the support structure can be suitable for different widths. The vehicle body is made more practical by adjusting the support rod (201) to the bottom of both sides of the vehicle body, and the first screw rod (206) is driven to rotate by the reduction motor (205). The first screw rod (206) cooperates with the threaded hole inside the lifting block (2) to adjust the two groups of lifting blocks (2) up and down, and the sliding groove (203) and the sliding rail (204) make the up and down adjustment of the lifting blocks (2) more stable, so that the vehicle body can be raised and lowered, and the vehicle body can be supported, so that the use effect of the support structure is better, and it is convenient to repair and use the car.
