[0010] The present invention has the following beneficial effects: a sheet metal finished workpiece, i.e., the workpiece, is placed lengthwise in a workpiece placement area, wherein the workpiece's elongated panel abuts the upper surface of the base, and the retaining pins are engaged with the front and rear sides or edges of the workpiece's elongated panel. Furthermore, the front block, the rear block, and the two side blocks each have respective retaining pins inserted into the punched holes of the workpiece's bent portion. Thus, through the dual retaining cooperation of the retaining pins with the workpiece's holes and the retaining pins with the workpiece's sides, the workpiece can be consistently retained in the fixture, thereby preventing warping and deformation. Furthermore, the front block, the rear block, and the two side blocks are all slidable, allowing the workpiece to avoid interference with the retaining pins on the front block, the rear block, and the two side blocks when the workpiece is first positioned and placed in the workpiece placement area. Furthermore, the thickness and length of the retaining pins can be specifically designed based on the diameter and position of the corresponding holes on the actual workpiece.
