ABSTRACT:
A quick-release reversible ratchet wrench has a control rod which extends through a bore in the ratchet drive body and the drive lug thereof for axial movement to shift a detent ball in the drive lug between coupling and release conditions. The control rod is urged to the coupling position by a helical compression spring in the bore which engages an annular shoulder at the upper end of the control rod. A second spring member has ends clamped to the drive body by an anchor plate and a flexible bearing portion which bears against a side of the control rod in a circumferential groove, between the annular shoulder and an enlarged head, for tilting the control rod laterally to hold the annular shoulder in engagement with the drive body to prevent accidental axial movement of the control rod to its release position. The anchor plate has a cover portion which covers and protects the reversing lever of the ratchet assembly and guards the control rod. An annular spacer may be disposed between the compression spring and the annular shoulder of the control rod.
