[0002] The laser cutting machine uses a high-power density laser beam to irradiate the material to be cut, so that the material is quickly heated to the vaporization temperature, evaporated to form holes, and as the light beam moves on the material, the holes continuously form a very narrow slit to complete the cutting of the material. Since there is no tool processing cost, laser cutting equipment is also suitable for producing small batches of parts of various sizes that could not be processed before.

[0003] When a laser cutting machine cuts a workpiece, it needs to clamp the workpiece through a limit clamp before cutting. In the prior art, a utility model patent with patent number CN202321645967.6 discloses a limit clamp for a laser cutting machine, in which the hexagonal bolt head of the clamp and the hexagonal bolt head of the screw can be rotated by a wrench, and can also be rotated by inserting an iron rod into the through hole of the clamp bolt head and the through hole of the screw bolt head, which is more convenient to use. Moreover, the overall structure of the clamp can be conveniently used to flexibly adjust the position and angle of the clamp according to workpieces of different shapes and structures.

[0004] However, during the assembly process, the clamping part needs to be fixed by turning the hexagonal bolt head of the clamp with a wrench. This connection method is relatively cumbersome and has poor overall fixing efficiency. Utility Model Content
