[0029] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the buffer 6 includes a protective cover 601, a spring 602 and an inclined block 603. The protective cover 601 is provided with a spring 602, and the top of the spring 602 is fixedly connected to the bottom of the inclined block 603, the outer wall of the inclined block 603 is slidably connected to the inner wall of the contraction cavity 103, and the outer wall of the protective cover 601 is fixedly connected to the inner wall of the circular cavity 104. When the vehicle needs to do four-wheel alignment and the wheel is pressed, the wheel first moves to the corner plate 503 through the inclined block 603. When passing through the inclined block 603, the inclined block 603 can move downward in the contraction cavity 103. The elastic force of the spring 602 is used to buffer the wheel when it is pressed onto the corner plate 503. After the wheel passes through the inclined block 603, the inclined block 603 is extended by the elastic force of the spring 602 to limit the wheel and prevent it from leaving the corner plate 503.

[0030] The use method and advantages of the utility model: When the pneumatic corner plate is working, the working process is as follows:

The transmission block 303 is driven to move by the extension of the cylinder body 203. The transmission block 303 drives the transmission plate 301 to rotate in the third groove 108. The ball bearing 302 can reduce the resistance of the transmission plate 301 when it rotates. When the transmission plate 301 rotates, it drives the transmission shaft 406 to rotate, so that the transmission shaft 406 slides in the second slide groove 405, and then the transmission rod 401 rotates around the second limiting axis 402, and then the third limiting axis 403 and the locking plate 404 rotate about the axis of the second limiting axis 402, so that the locking plate 404 contacts the locking plate 501 and locks it. After the wheel is pressed on, The cylinder body 203 moves in the opposite direction, so that the locking plate 404 is out of contact with the locking plate 501. At this time, the corner plate 503 and the locking plate 501 can rotate. The locking and unlocking are controlled by the cylinder body 203, and there is no need to manually remove the latch, which is convenient for people to use. When the vehicle needs to do four-wheel alignment and the wheel is pressed, the wheel first moves to the corner plate 503 through the inclined block 603. When passing through the inclined block 603, the inclined block 603 can move downward in the contraction chamber 103, and the elastic force of the spring 602 is used to cushion the wheel when it is pressed onto the corner plate 503. After the wheel passes through the inclined block 603, the inclined block 603 is extended by the elastic force of the spring 602 to limit the wheel and prevent it from being separated from the corner plate 503.
