The fixing clamp 32 is Y-shaped, with a channel for the laser to pass through in the middle, and the through slot provided on the support plate 33 is also used for the laser to pass through.

[0030] Working principle: when in use, the laser cutter body 14 cuts the stainless steel strip by outputting laser, and the electric push rod 15 is used to drive the laser cutter body 14 to move. The laser cutter body 14 is the output end of the laser cutting machine. The laser emitted by the laser generator of the laser cutting machine is focused into a high-power density laser beam through the optical path system. The laser beam is emitted from the laser cutting body and then irradiates the surface of the workpiece.

The two limit plates 22 can limit and guide the stainless steel strip to improve the cutting accuracy. The hydraulic cylinder 31 drives the fixing clamp 32 to move downward, so as to fix the steel strip. The support plate 33 is used to support and lift the steel strip from the bottom. Relying on the above setting, the fixing effect of the steel strip can be improved, and then To improve the cutting accuracy, the fixing clamp 32 is set in a Y shape, with a channel for the laser to pass through in the middle, and the through groove set on the support plate 33 is also used for the laser to pass through. When in use, the fixing clamp 32 moves down, which will drive the piston rod 42 to move down, thereby promoting extrusion, so that the gas in the piston cylinder 41 is injected into the gas outlet nozzle 45 through the gas outlet pipe 44, and then ejected from the bottom of the gas outlet nozzle 45. The ejected airflow can be used to clean the clamping part of the fixing clamp 32, thereby reducing the metal debris or foreign matter adhering to the steel belt, thereby reducing the foreign matter squeezed when the fixing clamp 32 is clamped, causing the steel belt to be concavely deformed. The filter cylinder 51 connected by thread is used to filter the incoming air by the filter screen 52, thereby preventing the air from clogging the gas outlet nozzle 45. The filter screen 52 is threadedly connected to the air inlet pipe 43, which can be easily installed and replaced. The spring 6 is provided, which can automatically drive the piston rod 42 to move up, thereby automatically completing the process of the piston cylinder 41 sucking air, which is convenient for the staff to use.
