Patent ID: 7721629

Claim:
A wrench configured to engage a fastener for rotation, the wrench comprising: a base comprising a face on one end and a drive body formed toward an end of the base opposite the face, the face including a surface that is oriented toward a fastener if the fastener is engaged by the wrench, the base having a conduit therein; a pair of jaws, wherein each of the jaws includes a gripping section and a foot, the foot being adapted to be slidably seated within the conduit formed in the base so that the jaws are carried by the base with the gripping sections of the jaws being opposed to each other adjacent to the face of the base, the foot having a threaded opening therein; a pair of threaded shafts seated within the base inside the conduit such that each of the threaded shafts passes through one of the threaded openings formed in the feet of the jaws such that rotation of the threaded shafts causes the jaws to be actuated toward or away from each other, wherein each of the threaded shafts includes a spurred member on an end that is external to the jaw through which the threaded shaft extends; and an adjusting ring disposed around the base such that the adjusting ring can be rotated about the base, the adjusting ring including a set of teeth that engage the spurred members of the threaded shafts such that rotation of the adjusting ring about the base causes rotation of the threaded shafts, thereby actuating the jaws toward or away from each other.
