Abstract
A rivet gun has a barrel, a handle assembly, a cylinder and a seal ring assembly. The handle assembly is mounted under the barrel and has a hydraulic shaft and a handle mounted around the hydraulic shaft and having an annular shoulder. The cylinder has a top cover, an annular body and a bottom seat. The top cover is mounted under the handle and contacts the annular shoulder. A diameter of the top cover is larger than a diameter of the annular shoulder such that an outer periphery of the top cover protrudes radially out from an outer periphery of the annular shoulder instead of being covered by the annular shoulder. The annular body is mounted detachably on the top cover. The bottom seat is mounted detachably on the annular body. The rivet gun is allowed to change cylinders of different sizes or types.
