That is, the first fitting portion 412 of the first vibration damping member 410 and the bottom wall 132 of the clamping groove 130 have the same shape, the second fitting portion 414 can extend outward from the periphery of the edge of the first fitting portion 412, and the contour of the second fitting portion 414 is matched with the side wall 134 of the clamping groove 130, so that when the clamping portion 30 is matched with the clamping groove 130, the clamping portion 30 and the clamping groove 130 are separated by the first fitting portion 412 and the second fitting portion 414, and vibration of the vacuum pump set 200 is prevented from being transmitted to the door main body 22 through the suction base 100 while the suction base 100 is fixed.

Since the contour of the second fitting portion 414 is matched with the side wall 134 of the clamping groove 130, the second fitting portion 414 can also be configured to be inwardly convex at the position corresponding to the positioning portion 136. When the clamping portion 30 is engaged with the clamping groove 130, the positioning portion 136 extends into the recess 32 to enhance the fixing effect of the clamping.
Referring to fig. 6 and 7, the position of the positioning portion 136 is preferably in the height direction of the clamping groove 130. In the process of matching the clamping groove 130 with the clamping portion 30, the positioning portion 136 can limit the extending distance of the clamping portion 30, and further the fixing effect of the connection is enhanced.
