PROBLEM TO BE SOLVED: To provide a monkey wrench for fastening or loosening a small/large nut or a bolt while momentarily gripping the head thereof when tightening the nut or bolt. SOLUTION: In a hole of the one-touch monkey wrench, a horizontally long round rod is provided which is cut at the middle into a semicircular rod 6 at the upper part and a semicircular rod 3 at the lower part. Adjusting screws 14 are formed in a protruded portion 4 and a recessed portion 5, certainly spaced from each other, of the semicircular rod 3 at the lower part. The semicircular rod 6 at the upper part has a flat ball around the center, a boss portion 7 on the side face of the flat ball, and a round rod and a spring at the lower part of a bow 8. The semicircular rod 6 is freely movable. So, the tool can momentarily fasten or loosen a small nut or a large bolt while using the adjusting screw for fine adjustment. The semicircular rod at the upper part and the semicircular rod at the lower part are locked and integrated together to grip the head of the nut or the bolt. COPYRIGHT: (C)2009,JPO&INPIT |
