Abstract
A rivet gun has a barrel, a handle, an annular flange, a pneumatic cylinder and a piston assembly. The handle protrudes downward from the barrel. The annular flange protrudes radially from the bottom end of the handle and has a bottom surface and a rotational angle alignment slot defined eccentrically in the bottom surface. The pneumatic cylinder is mounted under the handle and the annular flange and has a body and a top cover mounted on a top opening of the body and having a rotational angle alignment element mounted eccentrically on a top of the top cover and detachably engaging the rotational angle alignment slot of the annular flange. The piston assembly is mounted in the pneumatic cylinder. The rotational angle alignment slot and the rotational angle alignment element are both at least partially exposed to be visually observed from an appearance of the fully assembled rivet gun.
