An annular wrench includes a first ring for engagement with a hand, a second ring rotationally installed in the first ring for engagement with a tool bit, a one-way driving device arranged between the first ring and the second ring so that the first ring can drive the second ring in a direction through the one-way driving device, and a tab pivotally mounted on the first ring between a lying position and a standing position. In the standing position, the tab can be pressed for rotating the first ring.
