The driving mechanism 3 drives the mounting plate 1 to move upwards, and at the same time drives the rotating arm 6 to rotate, thereby sequentially driving the connecting arm 5 and the pressing block 4 to open obliquely outward. After the workpiece is placed on the mounting plate, the driving mechanism 3 drives The rotating arm 6 moves in the opposite direction, thereby sequentially driving the connecting arm 5 and the pressing block 4 to close inwardly, and the workpiece is clamped on both sides by the pressing block 4 and the mounting plate 1 .
