In order to ensure the stability of the movement when the offset occurs, the pressing force of the buckle plate on the channel plate is 0 in the embodiment, i.e., the buckle plate does not generate a pressing force on the channel plate, and the buckle plate only has a limiting effect. Therefore, the buckle plate (the second plate body) is virtually connected to the channel plate, and specifically, a gap can exist between the buckle plate and the upper surface of the channel plate, the gap can be 0-2 mm, and preferably 0, and no pressing force is generated.
