The ratchet shaft is hollow and comprises a front end having a section of hexagon, a rear end having a section of circle, and a guide in the rear end thereof. The guide is aligned with a flat extended inwardly from the front end of the ratchet shaft such that it can automatically align one shank pushed out of the ratchet cylinder with the forward end of the ratchet shaft prior to pushing the shank out of the ratchet shaft for use.
