[0002] A laser cutting machine emits laser from a laser, which is focused into a laser beam with high power density through an optical path system, and then the laser beam irradiates a workpiece to be cut on a processing platform. With the relative movement of the laser beam and the workpiece, the purpose of cutting the workpiece is finally achieved.

[0003] The Chinese utility model patent with the publication number of CN221473860U discloses a laser cutting machine. The columns at both ends of the gantry of this laser cutting machine are slidably installed on the surfaces of the side walls on both sides of the frame, and grooves are provided on the surfaces of the side walls on both sides of the frame, and slide rails and toothed rails cooperating with the columns of the gantry are provided in the grooves. It has the following defects: 1) The side walls on both sides of the frame need to be designed wider, with a reserved groove space on the surface, resulting in a relatively long distance between the loading and unloading position (i.e., outside the side walls on both sides of the frame) and the processing platform. When manually loading the workpiece from the loading and unloading position to the processing platform and unloading the workpiece from the processing platform to the loading and unloading position, the loading and unloading are very inconvenient, with high labor intensity and low efficiency; 2) The slide rails and toothed rails are arranged in parallel at intervals in the groove, and the teeth of the toothed rail are prone to accumulating dust, affecting the working performance. Therefore, the toothed rail needs to be frequently cleaned, which is time-consuming and laborious and inconvenient to use.

[0004] Therefore, there is still room for improvement in the prior art. Content of the Utility Model
