发明名称 Adjustable wrench
摘要 A squeeze type, rotating wrench has a toothed drive gear for receiving selected tool elements. The drive gear is driven in a selected direction by a push arm and reversible pawl upon squeezing of a pair of handles relative to each other. Reversing the direction of rotation is accomplished by pivoting the pawl from one position to another relative to the push arm.
