Furthermore, the vacuum generator 20 can generate suction in the upper region R1 through the through hole 150 , so that the moving element 330 of the clamping assembly 300 slides upward along the central axis 131 of the channel 130 .

When the moving element 330 slides upward, its inclined surface 331 will contact the inclined surface 341 of the contact element 340 and push the contact element 340 to deform the contact element 340 . Therefore, the protruding portion 342 of the contact element 340 can contact the locking portion 41 of the locking element 40 to provide further clamping force of the locking element 40 . In this embodiment, the moving element 330 and the contact element 340 may be made of metal material to reduce debris generated when the elements are in contact.

Referring to FIG. 8 , in this embodiment, the clamping assembly 300 includes a plurality of contact elements 340 , and the contact elements 340 are configured to be rotationally symmetric with respect to the central axis 131 of the channel 130 .
