Of course, instead of the H-shaped mount 40, an X-shaped mount may be used on which the pneumatic gripper 41 is mounted, and mounting slots are provided on the arm of the X-shaped mount, through which the position of the pneumatic gripper 41 can be changed. Because the mounting groove of the X-shaped mounting frame extends along the diameter of the plurality of pneumatic clamping jaws 41, the position of the pneumatic clamping jaws 41 can be adjusted more conveniently and accurately.

It should be understood that the above-described embodiments are merely preferred embodiments of the invention and the technical principles applied thereto. It will be understood by those skilled in the art that various modifications, equivalents, changes, and the like can be made to the present invention. However, such variations are within the scope of the invention as long as they do not depart from the spirit of the invention. In addition, certain terms used in the specification and claims of the present application are not limiting, but are used merely for convenience of description.
