Abstract (en)
[origin: ES296369U] A reversible ratchet wrench wherein the usual pawl member associated with the usual ratchet wheel located in the head end of an elongate, ratchet wrench body is rotated either clockwise or counterclockwise from one end position to an opposite end position for reverse wrench operation by an elongate, change-over finger that extends longitudinally of the wrench body to the handle end thereof and is pivotally mounted as a lever relative to the wrench body. The work arm end of the lever preferably freely engages a recess or notch in the pawl, while the power arm end of the lever preferably engages a resiliently urged ball detent for snap action in moving from one end position to the opposite end position, alternately, under the control of preferably opposite push button ends of a slide actuator located near the handle end of the wrench body for pressing by a finger of the one hand of a user holding the wrench by such handle end. The wrench body is preferably of composite formation, having a major, longitudinal, body part made of plastic and having mutually opposite faces that are advantageously shallowly recessed to provide plane longitudinal surfaces against which face plates of strong and durable material, preferably steel, are secured for supporting operative parts of the wrench.
