Abstract

An adjustable wrench with strength enhancing structural design includes a body including a grip end and a driving head. The driving head includes a fixed jaw and a movable jaw. The movable jaw engages and is operably movable in a groove. The groove includes two lateral walls facing oppositely and spacing from each other. Each of the two lateral walls includes a first surface and a second surface. The first surfaces of the two lateral walls face oppositely and are separated by a space. The first and second surfaces of each of the two lateral walls have a common edge and an included angle less than 90 degrees. The movable jaw includes two slopped surfaces corresponding to and abutting against the second surfaces of the two lateral walls.

Abstract

A simple open-end wrench includes a driving head including first and second jaws, a space delimited between the first and second jaws, first and second recesses extended from the space, a pawl pivotally embedded in the first recess, and a biasing mechanism received in the second recess and abutted against the pawl. The pawl includes an abutting end disposed outside the second recess and extended into the space. The pawl is pivotal to a position with the abutting end thereof disposed within the second recess.

Abstract

An adjustable wrench including a fixed jaw, a movable jaw, a handle, a shaft member and a stopper pin. The front end of the handle is pivotally connected with the fixed jaw. When the handle is reciprocally pivotally swung, the stopper pin is driven by the handle to reciprocally move toward the stopper section or away from a stopper section of the shaft member. Also, by means of the spring fitted on the shaft member disposed in the main passage of the fixed jaw, after the movable jaw is slightly opened, the movable jaw will be immediately restored to hold the bolt or nut. Therefore, the bolt or nut can be continuously wrenched at one time without troublesome operation. The adjustable wrench has fewer components which are easier to process and assemble.
