Abstract
A barrel assembly for a rivet gun has a barrel, a piston, a rear plug, a fluid tube, a control valve tube and a spring. The barrel has a cavity. The piston is mounted slidably in the cavity and has a rivet ejection passageway. The rear plug is mounted on a rear end of the barrel and has an assembling hole and a sliding passageway. The fluid tube is mounted detachably in the rear end of a head of the piston. The control valve tube is detachably mounted on the rear end of the fluid tube and is mounted slidably in the sliding passageway. With the fluid tube and the control valve tube, the barrel assembly efficiently prevents the high pressure air from continuously leaking out after the pin pulling action is finished.
