Abstract
In a tool bit driver, a body suitable for mounting on a square drive of a socket wrench is provided with a bit socket adapted for receiving a tool bit at one end of the body, and diametrically opposed grooves are formed to extend longitudinally within the socket. A spring is provided with resilient fingers seated within the socket grooves, and reversely bent ends are formed on each spring finger for engaging the bit in surface-to-surface contact for positively and releasably securing the bit in a driving position within the socket.
Claims11
A tool bit driver comprising a body having a non-circular drive opening, a non-circular bit socket and an intermediate through-opening of reduced cross-section connecting the drive opening and socket;
- the drive opening, socket and connecting through-opening being in coaxially aligned relation within the body;
- the bit socket having internal walls defining bit drive faces with a pair of spring finger retention grooves formed therein;
- and a spring formed of resilient material and having a pair of bit retaining fingers and a base connecting those fingers;
- the base of the spring having a minimum dimension greater than the maximum cross-sectional dimension of the intermediate through-opening of the body;
- the spring being insertable into the drive opening into an operating position within the body wherein the base of the spring is positively secured against unintended displacement within the drive opening of the body and the fingers of the spring extend through the intermediate through-opening and are biased by the spring material into seating engagement within the grooves of the socket.
