Abstract: An air gun firing operating system that uses compressed air to eject bullets by a purely mechanical device, and enables single firing or high-speed continuous firing. During the firing operation, the system uses a sliding shuttle tube that is able to slide back and forth in a linear displacement on a central axis between a bullet chamber and a cylinder. The sliding shuttle tube uses differential pressure variation in a pressure buffer chamber to achieve a stroke state that can be continuously changed, thereby achieving high-speed back and forth motion and continuous firing of bullets. The relevant driving position of a trigger device is provided with a sliding retainer, which is able to effect transient retaining of the sliding shuttle tube, thereby restricting the system for single firing, or discontinuing the retention to enable the system to be in a continuous firing operation state.
