Abstract
An extensive device is disclosed to connect a bit to a handle of a tool. The extensive device includes a rod, a polygonal sphere, a socket and a retaining element. The polygonal sphere is connected to the rod near an end. The socket includes a polygonal cavity, a tunnel and a groove. The polygonal cavity receives the polygonal sphere so that the surface of the polygonal sphere is in contact with the wall of the polygonal cavity. The rod and the socket are coaxial when the end of the rod is disposed in the tunnel. The rod can be pivoted relative to the socket when the end of the rod is located outside the tunnel. The groove is defined in the wall of the polygonal cavity. The restraining element is fit in the groove of the socket to keep the polygonal sphere in the polygonal cavity of the socket.
