A driving tool includes a block and an impactor received in a front and a rear chambers of a handle, a driving shank attached to the block, and a plunger engaged between the block and the impactor. The impactor includes a cavity formed in one end for selectively receiving the tip of the plunger and for impacting onto the plunger and the block and the driving shank when the tip of the plunger is aligned with and engaged into the cavity of the impactor. The block has a guide device for guiding the block and the driving shank to rotate relative to the handle.
