ABSTRACT:
An easily adjustable wrench having jaws that move relative to each other. The moving mechanism comprises a pinion gear which is pivotally mounted from one of the jaws and a gear rack on the other jaw with which the pinion gear engages. An actuating button pivots the pinion gear out of engagement with the rack for quick adjustment between the jaws while the pinion gear may be manually rotated for finer adjustments.
