A driving tool includes an elongate hollow handle formed with a longitudinally extending receiving chamber and an open rear end, a tubular shank mounted securely on a front end of the handle and confining an axial bore communicated with the receiving chamber, a telescopic retriever disposed in the receiving chamber, a rear cap mounted removably on the rear end of the handle, and a spring-loaded retaining unit mounted on the shank. The axial bore has a cross-section smaller than that of the receiving chamber. The shank has an open drive end adapted for receiving removably a tool bit. The telescopic retriever has a front end extendible into the axial bore to reach the drive and, and provided with a magnet member. The front end of the telescopic retriever is extendible forwardly to project from the drive end. The retaining unit is extendible radially into the axial bore so as to be adapted to retain removably the tool bit at the drive end.
