Abstract
A rivet gun has a barrel, a handle, a pneumatic cylinder and a two-step pressing assembly. The handle has a valve-mounting hole, a first mounting hole and a second mounting hole being cylindrical and defined in a bottom end of the handle. The pneumatic cylinder has an inlet bushing, an inner bushing and a control valve assembly respectively mounted in the aforementioned holes. The two-step pressing assembly is mounted on the handle and allows the rivet gun to be operated by two steps. The handle is structurally simple and has a low manufacturing cost. The bushings and control valve assembly are easily mounted in and detached from the handle so that assembling of the rivet gun is efficient.
