Abstract
A pipe wrench includes a body and a first jaw has one end fixed to the body, and a second jaw is slidably located in a first recess defined in the top of the body and is located beneath the first jaw. A resilient member is connected between the body and the second jaw. A first link has one end pivotably connected to an end of the second jaw. A second link has the first end thereof pivotably connected to the mediate portion of the first link. An adjustment member threadedly extends through a closed end of the body and contacts against the second end of the second link. The second jaw is quickly slid by the resilient member and controlled by the adjustment member, so that the object can be released and clamped quickly.
