Patent ID: 7686004

Claim:
A gun device comprising: a housing including an inner chamber formed therein and including a handle for being held by a user, and including a trigger for being actuated by the user, and including a gas supplying passage formed therein and communicating with said inner chamber of said housing for coupling to a pressurized gas supplying source and for selectively supplying the pressurized gas into said inner chamber of said housing, a feed tube attached to said housing for feeding a bullet into said inner chamber of said housing, and arranged for allowing said bullet to be selectively fired with the pressurized gas supplied into said inner chamber of said housing, a tubular member rotatably received in said inner chamber of said housing and including a bore formed therein, and including an opening formed therein and communicated with said bore of said tubular member for selectively aligning with said feed tube and for selectively receiving said bullet into said bore of said tubular member, and said opening of said tubular member acting to open or close said feed tube when said tubular member is rotated relative to said housing, a rotating device for rotating said tubular member relative to said housing, and a controlling device for controlling the pressurized gas to flow into said inner chamber of said housing and to fire said bullet, wherein said rotating device includes at least one helical groove, an actuating rod and a pin, said helical groove is formed in said tubular member and is communicated with said bore of said tubular member, said actuating rod is slidably engaged into said bore of said tubular member, and said pin is attached to said actuating rod and has at least one end slidably engaged in said at least one helical groove of said tubular member for rotating said tubular member relative to said housing with said actuating rod.
