[0020] Through the above-mentioned structural setting, the stepper motor 41 drives the screw rod 42 to rotate axially, and the two screw nuts 43 are respectively located on the two sections of external threads. Therefore, when the screw rod 42 rotates clockwise, the two screw nuts 43 move toward the opposite side. Conversely, when the screw rod 42 rotates counterclockwise, the two screw nuts 43 move toward the back side at the same time, thereby ensuring that the bending positions on both sides are consistent with the distance between the center lines of the sheet metal, thereby increasing the precision of the bending process.
