ABSTRACT:
A ratchet wrench includes a body which carries a shank adapted to be removably fitted into a socket head for the purpose of rotating a socket head to turn a nut in the socket onto or off of a bolt. A handle pivot pin is mounted on the wrench body at a side opposite the shank to have its axis parallel to and spaced from the axis of the shank. An elongated wrench handle is mounted on the pivot pin and is movable with respect to the wrench body between a first position wherein the handle fits into the wrench body and is thus locked with respect to angular movement between the wrench body and the handle and a second position where it is above and spaced from the wrench body and can rotate freely about the pivot pin to cause the wrench body to rotate freely about the axis of the shank.
