A frame holds parallel shafts. One shaft holds a crank handle; the second shaft holds a wrench socket. The socket is interchangeable so the wrench can be used for different sizes of nut. The shafts are connected by gears to transfer power from the crank to the socket. A "T" handled rod extends from the frame, with the cross-arm of the "T" long enough to be supported by adjacent wheel spokes.
