ABSTRACT:
An adjustable wrench. When the wrench is turned in a direction, the fastener is turned and when the wrench is turned in an opposite direction, the fastener is kept still. The wrench includes a handle having a fixed jaw, a movable jaw slidably provided on the handle, an adjusting worm for driving the movable jaw moving and an elastic supporting device. The fixed jaw has a holding surface facing the movable jaw, the holding surface has a driving face and a base face with one end connecting the rails and another end connecting the driving face. The base face rests against a fixed side of the fastener and the driving face rests against a movable side of the fastener which is a side next to the fixed side. The movable jaw has a holding surface facing the fixed jaw. The holding surface has a driven face that rests against a third side of the fastener which is a side opposite from the movable side, and an elastic supporting device has one end provided on the holding surface of the movable jaw to be elastically movable against the fastener.
