Abstract
A lock structure which automatically locks the screw drive upon deactivation of the screw drive and automatically unlocks the screw drive upon activation of the screw drive. The locking structure is responsive to the attaching and detaching of a driver such that the detaching of the driver from an input of the screw drive automatically locks the screw drive and attaching the driver to the input of the screw drive automatically unlocks the screw drive. This is achieved by providing an outer locking surface on the screw drive and a locking plate whose axial position is controlled by the position of the drive and having an aperture for mating with the outer locking surface and locking the screw drive.
