ABSTRACT:
This invention relates to an F figure wrench that comprises a holding rod, a moving part, a turning rod and a driving part. At one end of the holding rod, a concavity is made and two lugs are implemented; the concavity is made as a guide hole to accommodate the moving part, the lug holes of the two lugs are used as pivot holes for the driving part to be pivot-connected with the holding rod. Furthermore, a penetration is made on the holding rod and the moving part concentrically, and intersects through the concavity for installation of the turning rod. A cam eccentric to the turning rod axis is implemented on the turning rod; when the turning rod is turned, the moving part is pushed by the eccentric cam and moving along the guide hole in the holding rod. There is at least one clutch part on the end of the moving part and at least one match part on the driving part to match with the clutch part; with turning the turning rod, the match of the moving part with the driving part is under control, thereof the driving part is able to be adjusted or locked in position relatively to the handle of the wench.
