The present invention will be further described in conjunction with the above drawings in the following detailed description.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. example. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

It should be noted that when an element is considered to be "connected" to another element, it can be directly connected to the other element or the element. When an element is considered to be "set to" another element, it can be either directly disposed on the other element or.

All technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to the invention. The terminology used in the description of the present invention is for the purpose of describing particular embodiments and is not intended to limit the invention. The term "and/or" used herein includes any and all combinations of one or more of the associated listed items.

Referring to FIG. 1 , a workpiece fixing device 1 according to an embodiment of the present invention is used to mount a plurality of workpieces 2 .

The workpiece fixing device 1 includes a mounting plate 10 and a square pass 20 and an elastic member 30 mounted on the mounting plate 10.

The mounting plate 10 has a handle 12 protruding upward for conveniently accessing the workpiece fixing device 1.

A plurality of mounting slots 60 are defined in the edge of the mounting board 10. Each mounting slot 60 is for mounting a workpiece 2 and has a long edge 61 and two opposite short edges 63. The long edge 61 is downwardly punched with an abutting piece 611 and two positioning pieces 613. The positioning piece 613 is configured to position and carry the workpiece 2 . In one embodiment, the long edge 61 is substantially perpendicular to the short edge 63, the abutment piece 611 is substantially perpendicular to the mounting plate 10, and the positioning piece 613 is substantially "L" shaped.
