US Patent 7137514 Storage rail connectors for ratchet wrench sockets

A wrench socket retaining and releasing storage apparatus has a body with a base, a shank and a square drive retaining end, slide key fitting in a channel positively locks the socket in place by displacing lock balls transversely, the slide key being manually releasable by action of a sleeve that moves the slide key against a lock spring thereby urging the slide key upward, with the lock spring also urging a rail engaging tension ball downward, this releasing enabling a tapered spiral ejector spring to both urge the socket off the end, and through the tightest, lower coil of the spring, retain the entire assembly together thereby enabling both firm and fixed storage and ease of removal.
