The first motor is started at this time to drive the eccentric to rotate through the first rotary column, further pushing the first sliding blocks to move to the other side through the eccentric. As the elastic force of the first springs is larger than that of the second spring, the second sliders drive the second fixing block to overcome the elastic force of the second spring to move to the other side, further pushing out the stamped and shaped tableware.

During the process of stamping and pushing, and the process when the stamping block moves to one side to stamp, the stamping block pushes the sixth sliders, further pushing the third sliders to the same side. While at this time the fourth sliders move upwards under the elastic force of the fourth springs so as to be disengaged from the grooves and the second sliders are capable of sliding to two sides at this time. While during the process when the stamping block finishes stamping and moves to the other side, the sixth sliders are gradually released and the third sliders are gradually getting back to be fixed in the grooves and are fixed back in the grooves when the first slider pushes out the shaped tableware. At this time the rotation of the eccentric drives the first sliding blocks to overcome the elastic force of the
