ABSTRACT:
A ratchet wrench includes a head having a slot for receiving a pawl. A driving member and an actuator are rotatably engaged in the head. A spring is engaged in the actuator and includes an arm engaged in an oblong hole of the pawl for allowing the actuator to rotate and to move the pawl to either of the narrower ends of the slot. The driving member may be rotated by the head in one direction when the pawl is engaged in one of the narrower ends of the slot and may be rotated in a reverse direction when the pawl is engaged in the other narrower end.
