Open-end wrench for quickly turning an object
Abstract
An open-end wrench for quickly turning an object includes a driving end including a first jaw and a second jaw which cooperate together. One of the first and second jaws includes a recess defined therein. Further, a movable engaging member includes a body pivotally fixed in the recess by a pivot. The body is in a surface contact with a lateral wall of the recess, and the recess supports the body. The pivot is inserted through the body and is fixedly engaged with a wall of the recess. Further, an elastic member resiliently engages with the movable engaging member. Furthermore, the open-end wrench is turned in a first turning direction to turn the object and in a second turning direction to move relatively to the object.
