Abstract
A wrench includes a handle with a first jaw and a protrusion respectively extending from an end thereof. A surface is connected between the protrusion and the first jaw. A pivotal member is pivotally connected to the protrusion and has a groove defined in a periphery thereof so as to receive the protrusion and the surface. A second jaw extends from the pivotal member and an end plate ends the groove. A spring biases between the end plate and the surface. The width between the first jaw and the second jaw can be adjusted by pivoting the pivotal member.
