<p>The present invention may be used for rotating a polygonal object. A first wrench member may have a handle with two ends with a fixed jaw attached at a first end and with a cavity formed in the fixed jaw and first end. A second wrench member may be a movable jaw with a curved jaw attached to a ratcheting element. The ratcheting element may be slidably positioned in the cavity to position the curved jaw opposite the fixed jaw. The second wrench member may be constrained by the cavity and a cavity insert member to slide in said cavity about the center of an arc. The cavity insert member is positioned between a rearward wall of the cavity and the ratcheting element and retains the ratcheting element within the cavity.</p> |
