Mechanical optical shutter device for laser treatment equipment

The utility model discloses a mechanical optical shutter device for laser treatment equipment, and relates to the technical field of optical equipment. The mechanical optical shutter device comprises an optical shutter box, a driving assembly and a blocking assembly. The driving assembly and the blocking assembly are arranged in the optical shutter box. A driving shaft of the driving assembly can linearly reciprocate in the first direction, and the blocking assemblies and the driving shaft are sequentially arranged in the first direction and fixedly connected. The optical shutter box is provided with a light inlet and a light outlet, and the driving assembly drives the blocking assembly to reciprocate in the first direction so that the blocking assembly can avoid a linear light path between the light inlet and the light outlet or move to the linear light path to block light on the linear light path. As the blocking assembly is directly arranged on one side of the driving shaft in the first direction, compared
