The lifting frame 3 can slide up and down along the adjusting slide groove 202 for adjustment. The lifting frame 3 can be embedded in the lifting and releasing groove 103. Since the lifting frame 3 can slide along the adjusting slide groove 202 and be guided by the support frame 201, the shaking of the support frame 201 and the influence of the stability of subsequent vehicle lifting can be avoided. At the same time, the adjusting screw rod 203 is rotatable, and when the adjusting screw rod 203 is rotated, the height of the lifting frame 3 can be adjusted, which can facilitate the subsequent processing.
