The wrench includes a wrench body 10, a first jaw 14, a second jaw 15 and a ratcheting jaw 20. The wrench body has a head 12 and a curved slot 16 formed in an inner surface of the head. The ratcheting jaw 20 is a curved block capable of sliding forward and retracting backward relative to the curved slot. A spring 30 may be abutted between the wrench body and the ratcheting jaw to provide a driving force for the jaw in the curved slot. The ratchet wrench allows ratcheting rotations for applying a series of turning strokes to a bolt without disengaging between the strokes for applying a torque to the bolt head during a rotation in the forward direction as well as for ratcheting rotation during a backward rotation. |
