Abstract: A wrench for applying a force to a work piece comprises a handle having proximal and distal ends, top and bottom edges and a slot extending therethrough with a groove extending downward from the slot. A fixed jaw is mounted at the distal end of the handle having an inner, contact surface for contacting the work piece, and a moveable jaw is pivotally mounted at the distal end of the handle having an inner, contact surface for contacting the work piece. A spring is mounted in the handle having a distal end in contact with the moveablejaw for biasing the moveable jaw toward the fixed jaw. A slidable button is mounted on the top edge of the handle, with a spring mounted between the slidable button and the top edge of the handle. A connector is provided having a distal end fixedly attached to the moveable jaw and a proximal end fixedly attached to the slidable button by a pin. In operation, the pin rides in the slot and fits in the groove.
