Abstract
A combination of wrench and driving device includes a wrench, a first driver having an axis and a combining part on one end and a connecting part on the other end thereof, a second driver having a non-circular outer edge, and a retaining mechanism. The wrench has a driving part. The combining part is removably engaged with the driving part, and one end of the combining part away from the connecting part has a retaining edge. The second driver is axially coupled with the connecting part along the axis. The retaining mechanism, when the second driver rotates toward any vertical direction vertical around the axis to be coupled, prevents the profile of the combining part and the profile of the non-circular outer edge from completely axially overlapping each other. The non-circular outer edge is retained against the driving part of the wrench.
