<p>An adjustable pliers wrench (10) including a fixture (11) having a handle (12) and an opposing stationary jaw (13), a co-acting jaw (14) pivoted to the fixture (11) and a lever (16) pivoted to the co-acting jaw (14). A guide (25) is attached proximate the handle (12) and a locking element (24) is arranged on the guide (25) for reciprocal and canting movement. At least one attached biasing element (51) urges the locking element (24) toward the stationary jaw (13). An arm (21) is pivoted to the lever (16) and a cam (23) is pivoted to the arm (21) and to the locking element (24) so as to be movable between a first condition permitting the locking element (24) to reciprocate along the guide (25) and a second condition bearing against the guide (25) and canting the locking element (24) into frictional engagement against the guide (25).</p> |
