<p>A friction clutch wrench in the style of locking grip pliers for imparting torsion to an object. Jaws (11, 12) open to access the work from the side, and then close and lock rigidly around the work. Once locked inside the jaws (11, 12), the work engages a friction clutch ratchet mechanism (17) provided in the confronting jaw faces. When the wrench is turned in one direction about the work, the friction clutch grips the work and imports torsion to it. When the wrench is rotated in the other direction, however, the friction clutch (17) permits free rotation of the wrench about the work.</p> |
