The speed at which the punch is pressed down is greater than the speed at which the push rod is pulled down. The curve design of the eccentric wheel realizes a unique material receiving method of first clamping and then staying. After the punch leaves, the push rod is kept in a staying state by using a lever, so that the workpiece can maintain a stable position and posture. BRIEF DESCRIPTION OF THE DRAWINGS
