Abstract
A coupler is disclosed which is constructed of metal. The coupler comprises a cylindrical major part having a first cylindrical bore formed therethrough, the cylindrical major part being formed about its cylindrical outer surface with an externally threaded portion and a polygonal enlarged head; and a collar part having a second cylindrical bore formed therethrough, the second cylindrical bore being greater in diameter than the first cylindrical bore. The cylindrical major part and the collar part are coaxially arranged and integrated with each other to constitute a monobloc cylindrical structure. In practical use, the second cylindrical bore can serve as a silencer.
