[0006] Preferably, the four support pieces each comprise a connecting column, an installation block and a bolt, the four connecting columns are respectively welded at the four corners of the bottom end of the support plate, the four installation blocks are respectively welded at the bottom end of the four connecting columns, and the four bolts are respectively screwed through the four installation blocks.

[0007] Preferably, two sides of the support plate are each provided with a buckle groove, one inner side wall of the two buckle grooves is welded with a handle, and the other inner side wall of the two buckle grooves is respectively welded with the two handle.

[0008] Preferably, one side of each of the four clamping rods is welded with a handle.

[0009] In summary, the present application has the following beneficial technical effects: by inserting the four insertion blocks into the four rectangular holes, the four clamping rods are located at the four corners of the workpiece, and the clamping slots of the four clamping rods tightly clamp the four corners of the workpiece, respectively. Then, the two ends of the connecting rod are movably penetrated through the four insertion holes, and the limiting block is penetrated through the connecting rod and the bracket to limit the bracket, preventing it from being separated from the four insertion blocks and increasing the installation stability of the four clamping rods. Then, the four clamping rods can be used to position the workpiece. BRIEF DESCRIPTION OF DRAWINGS
