[0023] During actual use, the workbench 1 provides stable support for the side panels 2, and a top plate 3 is arranged above the side panels 2. Initially, the first lifter 4 is in a retracted state, and the first lifter 4 penetrates the top plate 3 and is connected to the knife seat 6. The motor 9 is started, and the motor 9 drives the forward and reverse screws 10 to rotate. The two sets of sliders 11 move toward each other under the limit of the slide frame 8 on the knife seat 6, and are adjusted to a suitable spacing to limit the material.
