Abstract

The present invention provides an improved rotation structure of a wrench (2), which mainly includes a first jaw annularly installed on a protrusion side of the wrench head, in which the protrusion is housed between the first and second protrusion ears of the wrench handle, and a pivotal bar is installed so that the wrench head and the wrench handle form a pivotal relationship. A positioning bar in a first housing groove of the wrench handle is pressed so that the positioning bar presses on an adjustment bar in a second housing groove, so that a second jaw on the front end of the adjustment bar forms a temporary detachment from the first jaw of the protrusion, for the convenience of bending and angle adjustment of the wrench head. Next, the positioning bar is released so that the adjustment bar is returned to its original position under the action of the front and rear springs, thereby achieving the effect of fastening the wrench head after bending and angle adjustment. Thus, the invented improved rotation structure of wrench (2) has industrial applications.
