Abstract
A ratchet wrench is provided which includes a handle having an exterior surface, a head coupled to the handle, a rotatable gear disposed in the head and having ratchet teeth, and a rotatable pawl moveable between a first pawl position in which the pawl is engaged with the gear to allow rotation of the gear in a first direction and substantially prevent rotation of the gear in a second direction and a second pawl position in which the pawl is engaged with the gear to allow rotation of the gear in the second direction and substantially prevent rotation of the gear in the first direction. The wrench includes an elongated rotatable rod disposed in the handle having an actuator disposed at a first end of the rod and inclined with respect to the axis of the rod, the rod being rotatable from a first rod position wherein the actuator biases the pawl to the first pawl position and to a second rod position wherein the actuator biases the pawl to the second pawl position. An operating mechanism is disposed at the exterior surface of the handle and coupled to the rod.
