Top (knurled brass sleeve): You pull it back to insert/remove bits. Bottom end (hex shank): Goes into a drill or hand brace. Inside: Spring + ball detent that locks a 1/4” hex bit in place. The longer hex shaft suggests it may have been used with older hand tools (brace, early drivers, or even impact-style tools).
