  • Patent number: 7665391
    Abstract: A multi-bit screwdriver comprises a housing with a bit chuck at the front end and bit assemblies retained within the housing. Each bit assembly has a tool bit at a front end and a contact surface at a back end. An actuator extends from each bit assembly for operative engagement by a user, for movement of the actuator and bit assembly between a forwardly extended in-use configuration whereat the bit assembly is positioned such that the tool bit extends outwardly from the housing, and the contact surface of the bit assembly is disposed in longitudinal force transmitting engagement against a forward facing abutment surface to preclude rearward movement of the bit assembly due to substantially longitudinally directed forces transmitted from the tool bit, and a retracted configuration whereat the contact surface of the bit assembly is removed in a lateral direction from the longitudinal force transmitting engagement with the forward facing abutment surface.
