The ring is placed on the flange and contains a plurality of channels corresponding in position to the through holes. By turning the ring to enter or exit the retaining members of the load tube into or from the through holes for preventing waste of paint balls and improving safety. The load tube further comprises a plurality of locking units for precise positioning in an open status, ensuring a facilitated passage and preventing jammed paint balls.

Abstract: A two-stage percussion device for a paint ball gun includes a piston tube and a push rod in conjunction with a barrel. A separation ring is disposed between the middle and the rear sections of the barrel. The piston tube is accommodated in the middle section of the barrel. The push rod is disposed in the rear section of the barrel. A plunger is provided at the front end of the push rod. The rear section of the push rod passes through the separation ring and is disposed with a piston block. An air storage space is formed between the plunger and the separation ring.

Abstract: A quick-release connector structure for an air tank includes a connector body incorporated with an air tank and a seat block. The seat block is secured to the air tank and comprises a valve having a post extending forwardly. The valve is acting as a switch to turn the air tank on and off. The connector body comprises a first passage and a second passage. The first passage comprises an air release hole and a through hole. A thimble is disposed in the first passage. A quick-release wrench is provided in a recess disposed on the connector body. The quick-release wrench corresponds to the through hole and is secured by a fastener. By turning the quick-release wrench, the high-pressure air remaining in the pipe is released.

Abstract: A pressure control device for a paintball gun incorporated with a gun body, a pressure pipe, a high-pressure tank includes a pressure switch connected to a connecting block of the gun body. The pressure switch comprises a block having an inhaling hole and an exhaling hole at respective ends. The inhaling hole of the block is connected with one end of the pressure pipe. The other end of the pressure pipe is connected with the high-pressure tank. The pressure switch is sleeved with a sliding block. The sliding block has a circular ring along its inner wall to guide the inhaling hole and the exhaling hole of the block. When rotating a ring of the pressure switch, the sliding block will move relative to the ring to block the high-pressure air from passing through. Thus, the paintball gun is protected from triggering accidentally to hurt people.

Abstract: A paintball gun is to directly shoot a paintball by using pressurized air to avoid the fast movement of a hammer protruding from a barrel from hurting the hand of a user. A low-pressure regulator is turned to block a port of the barrel to prevent the pressurized air from entering into the barrel to avoid hurting people by accidentally pulling the trigger.
