The second air bearing member 41 is received in the third receiving hole 204 and the stopper rod 42 passes through the communication hole 205. The air hole 101 is used for vacuumizing or injecting air into the third accommodating hole 204, so that the second air floating member 41 slides towards a direction close to or far away from the bottom plate, and the limiting rod 42 is driven to retract or pass through the communication hole 205.
In this embodiment, the second air-floating piece 41 is cylindrical, the limiting rod 42 is cylindrical, and the limiting rod 42 and the second air-floating piece 41 are coaxially arranged, so that the second air-floating piece 41 uniformly applies an axial acting force to the limiting rod 42. The diameter of the second air-floating member 41 corresponds to the diameter of the third receiving hole 204 so that the second air-floating member 41 can block the third receiving hole 204. When vacuum is pumped or air is injected into the third receiving hole 204, the second air-floating member 41 slides towards a direction close to or away from the bottom plate, and further drives the limiting rod 42 to retract or pass through the communication hole 205. When the limiting rod 42 passes through the communication hole 205, the limiting rod 42 can play a role in positioning the workpiece 200; when the stopper rod 42 is retracted into the communication hole 205, the stopper rod 42 does not affect the processing of the workpiece 200.

When air is injected into the third accommodating hole 204, the second air floating member 41 slides in a direction away from the bottom plate 10 to compress the second spring 43, and the second spring 43 is compressed to play a certain buffering role; when a vacuum is drawn into the third receiving hole 204, the elastic potential energy of the second spring 43 in the compressed state is converted into kinetic energy, and the second air-bearing member 41 is accelerated to slide toward the bottom plate 10.
