    Abstract: The ratchet wrench with handgrip ratchet control includes an axially rotatable rod installed within the handle. The rod is connected to a handgrip disposed externally to the handle. The rod rotates upon manual rotation of the handgrip. An end of the rod adjacent to the wrench head and opposite the handgrip has an axially offset flexible spring pin extending therefrom that engages a blind hole or receptacle in the back of the pawl in the wrench head. Rotation of the handgrip rotates the rod and its pin to swivel the pawl in the selected direction to lock rotation of the wrench drive in one rotational direction, while allowing rotation in the opposite direction. Rotation of the handgrip in the opposite direction reverses the above-described operation. One or more detents may be provided to secure the handgrip in the desired pawl actuating position.
