[0002] In the manufacturing industry, sheet metal is often subjected to operations such as gas cutting, bending, and forming to produce sheet metal parts that meet specifications. The first step in using large sheet metal is cutting. Existing cutting equipment generally includes benchtop cutting machines or cutting beds that use abrasive wheels, and laser cutting machines. Abrasive wheel cutting is noisy, polluting, and labor-intensive, which has an adverse effect on the health of operators. For this reason, laser cutting machines are widely used in the sheet metal industry.

[0003] Existing laser cutting machines have low load-bearing capacity. The bottom of the cutting machine is often supported by several support legs. These support legs have a certain height and diameter. When the machine needs to be moved, they are easily damaged, causing the machine to become unbalanced and making it difficult to use. In addition, the laser head used in existing laser cutting machines has poor cooling performance and cannot support the laser head for long-term use. Summary of the Invention

[0008] The present invention is further configured such that: the laser base is slidably connected to the frame, and a chain box is provided on one side of the frame.

The connecting seat 81 is used to connect with the laser base 7, and has a laser hole in the middle for the laser emitted by the laser generator to enter the lens fixing seat 82 through the laser hole. The lens fixing seat 82 includes a sealing shell with a sealing cavity inside, and a lens assembly is installed in the sealing cavity. The laser emitted into the lens fixing seat 82 passes through the lens assembly and is emitted by the laser nozzle 83. In addition, a coolant circulation pipe is provided inside the sealed cavity.
