[0027] A screw 16 is fixed on the lower surface of the pressing plate 2. Due to the restrictions of the rotating block 13 and the annular groove 6, and due to the matching relationship between the screw 16 and the threaded hole 11, the rotation of the guide rod 12 will drive the screw 16 to move slowly inside the guide rod 12. A limiting rod 14 is fixed on the lower surface of the pressing plate 2, and a positioning rod 15 is fixed on the lower surface of the pressing plate 2. The positioning rod 15 has a positioning effect on the movement of the pressing plate 2.

[0028] Embodiment 2

[0029] On the basis of the first embodiment, in order to realize the integrated clamping of the workpiece, a laser cutting knife 3 is fixed on the surface of the laser cutting machine body 1, a positioning hole 7 is opened on the surface of the laser cutting machine body 1, a through hole 5 is opened on the surface of the laser cutting machine body 1, an annular groove 6 is opened on the arc surface of the through hole 5, and a rotating block 13 is fixed on the arc surface of the guide rod 12;

[0030] There are multiple groups of positioning holes 7, which are symmetrically distributed on the surface of the laser cutting machine body 1. There are multiple groups of positioning rods 15, which are symmetrically distributed on the lower surface of the pressing plate 2. The positioning rods 15 correspond to the positioning holes 7. The positioning rods 15 are clamped in the positioning holes 7. The two are movably connected, which plays a role of positioning group for the movement of the pressing plate 2 to prevent the pressing plate 2 from shifting when moving.

[0031] There are multiple groups of through holes 5, which are symmetrically distributed on the surface of the laser cutting machine body 1. There are multiple groups of guide rods 12, which are symmetrically distributed inside the laser cutting machine body 1. The guide rods 12 correspond to the through holes 5, and the guide rods 12 are clamped in the through holes 5, and the two are movably connected.

Since the first gear 9 and the second gear 10 are clamped, the rotation of the second gear 10 will drive the first gear 9 to rotate, and the rotation of the first gear 9 will drive the guide rod 12 to rotate. Due to the restrictions of the rotating block 13 and the annular groove 6, and due to the matching relationship between the screw 16 and the threaded hole 11, the rotation of the guide rod 12 will drive the screw 16 to move slowly inside the guide rod 12, and the movement of the screw 16 will drive the pressure plate 2 to move. When the limit rod 14 is clamped in the hole opened on the surface of the workpiece and the lower surface of the pressure plate 2 is close to the surface of the workpiece, the motor 8 is turned off.
