Abstract: A dual-purpose type gas-valve structure especially related to a gas-gun gas-valve used for controlling the igniting and releasing of gas. It is specially designed with the horizontal and vertical gas entrance types coexisting structure to facilitate selecting different types to insert and connect the high-pressure steel cylinder depending on the gun type. It mainly consists of a box-body set with several connected horizontal and vertical channels inside; wherein a group of vertically intersecting channels located below can respectively insert into the high-pressure steel cylinder from the horizontal entrance and the vertical entrance from outside; wherein the lower-layer horizontal channel located at the upper f-type channel belongs to the high-pressure gas control room and the touch-press port, and the gas can be thereby released to the vertical channel and strongly ejected out through the upper-layer horizontal channel to instantaneously propel and launch out the bullet of the connecting barrel.

Abstract: The touch-type gas control valve contains a button, a spring, a hollow body, an O-shaped ring, and a stem. The button is configured to be slidable in and out of a top side of the body. The body has a number of outlets around the lower section's circumference and an inlet on a bottom side of the body. The spring is housed inside the body. The ring is positioned around the inlet. The stem has a semi-spherical head at a bottom end and threads around a top section. The stem runs through the ring, into the body through the inlet, through the spring, and is fastened into the bottom side of the button. The ring is sandwiched between the semi-spherical head and the bottom side of the body by the resilience of the spring when the button is not depressed.

Abstract: A paintball loading device is provided for a paintball gun, including magazines, a control switch, a movable cylinder, and a multi-linkage trigger. The magazines include an upper magazine and a lower magazine respectively configured above and below the movable cylinder, allowing paintballs to be positioned in tandem from the upper and lower magazines to a paintball feeding port behind the movable cylinder, and paintball blocking buttons including a lower paintball blocking button and an upper paintball blocking button. The control switch is configured below the lower paintball blocking button and is capable of a transversal movement to selectively set the paintball blocking button at a closed condition. The movable cylinder is moved with the multi-linkage trigger, thereby moving the upper paintball blocking button and lower paintball blocking button back to an open condition for the entry of paintballs into the paintball feeding port.

Abstract: A paintball gun structure, which is capable of rotating and lift up a paintball, mainly includes a barrel and a rubber collar. The rubber collar is connected with the barrel in the middle of a bore thereof, where a conical slide rail element is projected from an upper side of an inner face of the rubber collar. A paintball is rotated upward and lifted up to increase range and strike force after it is passed through the barrel and shot out of a muzzle of the barrel.
