ABSTRACT:
A wrench includes a first handle provided with a first rotation seat, and a second handle provided with a second rotation seat rotatably mounted on the first rotation seat of the first handle. Thus, the first rotation seat of the first handle can be rotated relative to the second rotation seat of the second handle, so that the first handle has a driving face inclined with that of the second handle, thereby facilitating the user operating the first handle or the second handle to rotate the workpiece.
