Abstract

A ratchet wrench comprises a wrench body that forms a ratchet wrench featuring two torque outputs, of which one is in operation by rotating a rotatable shank to drive rotation of a driving head and the other is in operation by reciprocally wrenching the wrench body to drive rotation of the driving head so as to couple with a socket. The wrench body has a head portion forming a circumferential slot in which a notch is designed at a location close to a stem portion so that the notch is made in communication with a channel 121 defined in the stem portion and the notch is not in direct communication with the central bore of the head portion, whereby a configuration that ensures an intact ring-like structure of the circumferential slot of the head portion is provided in order to ensure structural strength and the life span of the ratchet wrench.
