Connector for rapid connection of screw driver shaft and grip does not require compressed air for fitting, has connection part with conical bore containing steel balls and pressure spring

摘要

The connector has a hollow tubular connection part (20) connected to a grip at the rear end. It has a polygonal central bore (201) with rear shoulder (21) and conical openings (23) for steel balls (24). A conical pressure spring (50) is fitted into the bore to prevent entry of the balls into the bore. A ring-shaped guide body (25) has a raised ring (27) charged by a helical pressure spring (22) fitted to the shoulder. A space (26) between the ring and a ring-shaped cap (202) holds the balls. The polygonal shaft of a screw driver fitted into the bore has a ring-shaped recess to engage with the steel balls.
