ABSTRACT:
A one-way monkey wrench includes a handle, a stationary jaw, a movable jaw, a worm and a one-way mechanism. The handle defines a groove, an opening in communication with a section of the groove and a tunnel. The stationary jaw is formed on the handle. The movable jaw is movably installed on the handle, and includes a rack movably positioned in the groove. The worm is rotationally positioned in the opening and engaged with the rack. The one-way includes a tongue movably positioned in the tunnel. The tongue includes an end, a sliding facet near the end and a pushing facet near the sliding facet. The sliding facet slides on an object when the one-way monkey wrench is rotated in a direction. The pushing facet pushes the object when the one-way monkey wrench is rotated in an opposite direction.
