ABSTRACT:
A hand tool includes a driving member, and a wrench body mounted on the driving member. The wrench body includes a handle, a driving head mounted on an end of the handle, and a locking portion rotatably mounted on the driving head and inserted into the mounting hole of the driving member. Thus, the wrench body can drive the driving member to rotate through 360 degrees reciprocally so as to rotate and unscrew the nut successively, so that the driving member can be used to unscrew the workpiece easily and rapidly.
