Air gun firing operating system

Abstract

The present invention provides an air gun firing operating system that uses compressed air to eject bullets by purely mechanical means, and enabling 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 line between a bullet chamber and a cylinder. The sliding shuttle tube is provided with a sliding column, and relative linear motion between the sliding column and the end opening of the cylinder determines critical opening and closing to obtain air pressure blasts, 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 opening the sliding retainer to enable a continuous firing operation.
