Abstract
A wrench adapted to engage a workpiece to drive the workpiece rotationally. In one embodiment, the wrench comprises a handle, a head, a first jaw, a track, a second jaw, and a biasing member. The first jaw is disposed on the head such that the position of the first jaw is adjustable toward and away from the jaw support along a first path, thereby enabling the wrench to be adapted for engagement with workpieces of different sizes. The second jaw is slidably seated in the track formed on the jaw support to slide along a second path between a first position and a second position. The second jaw further cooperates with the first jaw to grasp a workpiece therebetween and drive the workpiece in a first rotational direction if the head is driven in the first rotational direction by the handle. If the head is driven by the handle in a second rotational direction the engagement between the second jaw and the workpiece applies a force to the second jaw that slides the second jaw from the first position toward the second position, which enables the head to be rotated independently from the workpiece in the second rotational direction
