Example (b):

a laser engraving machine lifting shield 2 is shown in figures 1-2 and comprises a mounting frame 1 and a shield 2, wherein the mounting frame 1 is arranged on a machine body of the laser engraving machine, and a machine head of the laser engraving machine is positioned between the mounting frame 1 and the shield 2.

The inner wall of the shield 2 is provided with a sound attenuation layer, so that the noise generated when scraps are splashed onto the shield 2 during processing can be reduced. The guard shield 2 on be equipped with observation window 3, observation window 3 can also make the staff learn the processing condition when guaranteeing that guard shield 2 plays the guard action.

A driving assembly for moving the shield 2 is arranged between the shield 2 and the mounting frame 1. The driving assembly comprises a driving rod 10, a first supporting rod 11, a second supporting rod 12 and a connecting rod 13, the mounting rack 1 is provided with the driving rod 10 connected with a power source, and the driving rod 10 is movably connected with the mounting rack 1 through a connecting pin.

The other side of the mounting rack 1 is provided with a first supporting rod 11 through a connecting pin, and the first supporting rod 11 can rotate. One end of the first supporting rod 11 is movably provided with a second supporting rod 12 through a connecting pin, one end of the second supporting rod 12 is connected with the driving rod 10 through a connecting pin, and a connecting rod assembly is arranged between the other end of the second supporting rod and the first supporting rod 11.
