摘要

An improved screwdriver in which a replaceable bit (16) is removable secured to a mandrel (56) by the bit (16) being axially slidable in an axial socket (14) in the end of the mandrel (56). The bit (16) is movable from a position coaxially aligned with the socket (14) to a position out of therefrom, to assist in the engagement and driving of misaligned screws (26). A resilient split-ring (30) which serves to retain the bit (16) in the socket (14) is carried by and with the bit (16). With each new bit (16) a new split-ring (30) is also provided.
