[0036] With the increase of use time or frequent vehicle maintenance operation, the hard rubber on the surface of the top plate 6 can be worn, which affects the friction with the bottom of the vehicle and the overall stability, when the top plate 6 needs to be replaced, the operator only needs to manually pull the plug rod 51 outward, so that the plug rod 51 overcomes the elastic force of the reset spring 52, slides outward in the inner wall of the fixed block 4, until the plug rod 51 is disengaged from the plug-in cooperation with the positioning hole 63, at this time, the top plate 6 can be easily taken off from the top end of the fixed block 4, then a new top plate 6 can be installed, this quick release design greatly facilitates the maintenance and replacement operation of the parts, ensures that the foot support can continuously maintain good use performance, meets the long-term stable demand of vehicle maintenance work.
