By pressing the inclined surface, stress is applied to the long clamping plate (103) and the short clamping plate (109), causing them to move away from each other.

The movement of the long slide plate (301) will apply stress to the inclined plate (308) through the inclined groove (306). Through the stress, the inclined plate (308) will drive the short slide plate (307) to move closer to the guide rail base (201). This will cause the airbags (302) on the long slide plate (301) and the short slide plate (307) to abut against the side of the guide rail base (201). When they come into contact with the guide rail base (201), they will deform and form a flexible buffer layer. S3. Finally, start the motor (203) to make the lead screw (204) rotate, and drive the slider (205) to slide in the slide rail (202) through the thread. The offset of the guide rail is displayed in real time by the linear detector (207) using laser detection method, while the side detector (206) detects the accuracy and stability of the slider (205) when it moves.
