Abstract: An optical element driving mechanism is provided and includes a fixed assembly, a movable assembly, a driving assembly and a stopping assembly. The fixed assembly has a main axis. The movable assembly is configured to connect an optical element, and the movable assembly is movable relative to the fixed assembly. The driving assembly is configured to drive the movable assembly to move relative to the fixed assembly. The stopping assembly is configured to limit the movement of the movable assembly relative to the fixed assembly within a range of motion.

Abstract: A barrel for prohibiting the paintball from dropping therefrom is provided by the present invention. The barrel includes a main body and an elastic ring. In which, a rear end of the main body is formed with a combining portion to combine with a paintball gun, and an extension is extended rearward from the combining portion. A bore penetrates through the main body, the combining portion and the extension. Around an outer periphery of the extension is disposed an annular groove, and at least one slot is formed in the annular groove, while the slot communicating the bore proximate to the extension. In addition, the elastic ring has a smaller perimeter than that of the annular groove. The elastic ring is disposed in the annular groove, and a part of the elastic ring sinks into the slot, overlapping a part of the bore.

Abstract: A paintball gun includes an air valve and a body portion, in which the body portion includes a paintball hole, a communicator, a piston, an axle and a bolt. By the pneumatic control of the air valve, the piston is pushed between the first and second positions, and the movement of the bolt is controlled between the third and fourth positions, so as to control the pneumatic air to flow out of the projection passage to project the paintball.

Abstract: A paintball gun includes an air valve and a body portion, in which the body portion includes a paintball hole, an axle sleeve and a bolt. By the position change of the air valve, the movement of the bolt is, therefore, controlled between the third and fourth positions, so as to selectively turn the effusion passage open or closed to control the pneumatic air to flow out of the projection passage and projection hole to project the paintball.
