The socket shell comprises an interior, an inserted groove formed on an inner periphery of the socket shell longitudinally, an outer recess at the bottom of the socket shell, an inserted hole and a positioning slot formed at the bottom of the socket shell. The upper portion of the inserted groove has a C-shaped groove. The bottom of the inserted groove has a rectangular groove and an outcurved groove adjacent to the rectangular groove. A solid shortened copper plate is inserted in the inserted hole. A rigid, hollow elongated copper plate is inserted in the inserted groove.
