Abstract

A rotation locking mechanism for locking the rotatable torque adjuster of an adjustable torque wrench against unwanted rotation while permitting wanted rotation for intended torque adjustment. The rotation locking mechanism of the present invention has a selectively rotatable component for locking against unwanted rotation thereof while permitting wanted rotation thereof, the rotatable component comprising rotation application means for selective application of wanted rotation to the rotatable component by external engagement with the rotation application means, the rotation locking mechanism comprising clutch means coupling the rotatable component to a rotation anchor by way of the clutch means, the clutch means being normally engaged to clutch the rotatable component to the rotation anchor whereby to anchor the rotatable component against unwanted rotation and the clutch means being able to temporarily disengage to unlock the rotatable component for intended rotation.
