High-output-power annular carbon dioxide laser

The invention discloses a high-output-power annular carbon dioxide laser, and relates to the technical field of carbon dioxide lasers. Comprising a base, the interior of the base is fixedly connected with a laser body, and the interior of the base is provided with a protection assembly; the protection assembly comprises a pipeline, and the inner wall of the pipeline is fixedly connected with a limiting block. According to the high-output-power annular carbon dioxide laser, when a laser body inclines and falls, a pipeline inclines, a gravity ball extrudes an air bag I to be matched with an air pressure bin, a toothed bar to move, a gear and a cover plate, a storage bin is opened, and a safety air bag is popped out, and when the laser body vertically falls, the toothed bar is made to move through cooperation with an air bag II, a spring II, a power rod, a hydraulic bin I and a transmission rod I; the safety air bag is popped up; meanwhile, when a toothed bar moves, a second transmission rod moves upwards, a sec
