ABSTRACT:
A rotating bi-directional pneumatic gun has a body and a guiding tube mounted rotatably in the body. The guiding tube has an outer surface, a front notch, a rear notch, a front groove and a rear groove. The front notch and the rear notch are defined longitudinally in the outer surface of the guiding tube and are kept from communicating with each other. The front groove and the rear groove communicate respectively with the front notch and the rear notch and each have multiple inclined bores extending respectively toward the front end and the rear end of the barrel. Rotating the guiding tube can change the direction of air flow of the pneumatic gun, and the rotating bi-directional pneumatic gun is convenient to operate and easy to assemble.
