[0002] As one of the core components of the laser cutting machine, the laser head is the output device of the laser cutting machine. It is focused into a high-power density laser beam through the optical path system. The laser beam is irradiated along the nozzle to the surface of the material, reaching the melting point of the material, and finally forming a cut in the material to achieve the purpose of cutting.

[0003] Most of the existing laser heads are connected to the laser cutting machine as a whole. After the staff has finished the inspection, they cannot disassemble the machine for overhaul, which will reduce the staff's work efficiency. At the same time, when the laser head is damaged, the cutting equipment needs to be replaced as a whole, which increases the production cost.

[0004] To this end, we propose a laser cutting device that is convenient for replacing the laser cutting head. Utility Model Content
