[0037] Specifically, in use:

[0038] In the gantry laser cutting machine, the cross beam 22 realizes horizontal movement by sliding on the guide rails 5 on the top of the two groups of support frames 3. The guide seats A8 and B9 in the driving mechanism are connected to different positions on the surface of the cross beam 22. The elastic sleeve rail A11 on the guide seat A8 is connected to the bottom of the moving seat 6, and the elastic sleeve rail B10 on the guide seat B9 is connected to the side of the concave block 15.
