The workbench includes a clamping table surface and a base. Longitudinal chutes and two longitudinally arranged transverse chutes are opened on the clamping table surface. Transverse sliders are horizontally slidably connected in the transverse chutes. Both of the two transverse sliders are connected to a connecting seat below. A transverse screw rod is rotatably connected to the workbench. The transverse screw rod is threadedly connected to the connecting seat. First clamping plates are connected above the transverse sliders. Two longitudinal sliders are longitudinally slidably connected on the longitudinal chutes. Second clamping plates are connected to the longitudinal sliders.
