The upper support is formed by welding a support pin and a rib plate, the support pin can enter a vehicle body fabrication hole to position a vehicle body, and the rib plate plays a role in reinforcing and supporting during empty prying and stacking. The underframe is the frame that comprises two longerons and many crossbeams, and the grid board has been arranged at both ends around the underframe, tramples when making things convenient for the workman to operate. The bottom of the longitudinal beam of the bottom frame is in contact with a roller shaft of a roller bed or a supporting block of a conveying chain, and when the roller shaft/the conveying chain rotate, the skid drives a workpiece to move together through the bottom frame and the upper support, so that the function of conveying the vehicle body is realized.
