Abstract
An adjustable pliers wrench including a fixture having a handle and an opposing stationary jaw, a co-acting jaw pivoted to the fixture and a lever pivoted to the co-acting jaw. A guide is attached proximate the handle and a locking element is arranged on the guide for reciprocal and canting movement. At least one attached biasing element urges the locking element toward the stationary jaw. An arm is pivoted to the lever and a cam is pivoted to the arm and to the locking element so as to be movable between a first condition permitting the locking element to reciprocate along the guide and a second condition bearing against the guide and canting the locking element into frictional engagement against the guide.
