レスされる。``Operation'' Therefore, when the upper and lower hand levers 4 and 5 are grasped with both hands, and the upper hand lever 5 is opened upward about the pin 6, the lever 5 is pivoted to the eccentric position of the front end 5'. As the reciprocating sliding rod 7 slides slightly from the position shown in FIG. 2A to the position shown in FIG. A gap is generated between the plunger 1 and the rear end, the cam 10 rotates in the direction of the arrow a by the force of the coil spring 11, and the distance t between the rear end of the plunger 1 and the center of the cam 10 increases. In this state, when the upper hand lever 5 is lowered, the reciprocating sliding rod 7 and the short rod 9 will forcefully slide slightly forward according to the ladder principle as shown in FIG. The workpiece between the extrusion workpiece receiver 3 and the front end of the plunger 1 is deformed toward. By repeating this operation, the workpiece is pressed into the desired shape.
