SCREWDRIVER

摘要

A screwdriver includes a handle (102) having a handle channel (124) extending therethrough and a shaft (104) extending from a proximal end (128) insertable into the handle channel to a distal end (130) including a bit opening (137) sized to receive a proximal portion of a bit therein in combination with a locking sleeve (106) slidably receiving the shaft therethrough and positionable over the shaft distally of the handle and a spring (170) slidably received within the locking sleeve channel over the shaft. A coupling member (180) received over the shaft distally of the locking sleeve is movable from a biased first configuration in which a locking element (166) protrudes radially into the bit opening to lockingly engage a bit received therein and a second configuration in which the coupling member is retracted proximally to compress the spring and permit the locking element to move radially out of the bit opening to permit the bit to be removed therefrom.
