At the same time, during the rotation of the reciprocating lead screw 7, the rotation of the reciprocating lead screw 7 will drive the moving block 14 to rotate. However, at this time, the moving block 14 is limited by the limiting column 18, resulting in the moving block 14 only being able to move horizontally through the reciprocating groove on the surface of the reciprocating lead screw 7 during the rotation of the reciprocating lead screw 7.

After the first inclined block 602 moves a certain distance, the first inclined block 602 will contact and squeeze the second inclined block 605 to push the second inclined block 605 to rise. The rise of the second inclined block 605 will drive the T-shaped plate 604 to move. At this time, the T-shaped plate 604 will compress the second elastic telescopic rod 603. The movement of the T-shaped plate 604 will drive the fixed column 606 to move. The movement of the fixed column 606 will drive the top round block 607 to move. After the top round block 607 moves a certain distance, the top round block 607 will contact and squeeze the bottom of the placement table 13 to push the placement table 13, which can improve the discharging speed of the device, avoid discharging jams, reduce the subsequent processing workload, and improve the use efficiency of the device.

After the first inclined block 602 moves a certain distance, the first inclined block 602 contacts and presses against the second inclined block 605 to push the second inclined block 605 to rise. The rise of the second inclined block 605 drives the T-shaped plate 604 to move. At this time, the T-shaped plate 604 compresses the second elastic telescopic rod 603. The movement of the T-shaped plate 604 drives the fixed column 606 to move. The movement of the fixed column 606 drives the top round block 607 to move. After the top round block 607 moves a certain distance, the top round block 607 contacts and presses against the bottom of the placement table 13 to push the placement table 13, which can improve the discharging speed of the device, avoid discharging jams, reduce the subsequent processing workload, and improve the use efficiency of the device.
