ABSTRACT:
A quick-release socket adapter includes a hollow elongated casing having a hollow polygonal coupling rod at one end for holding a socket, a hollow ratchet socket wrench coupling portion at an opposite end for coupling to a ratchet socket wrench, a spring, a stop rod inserted into the casing and forced by the spring to push a steel ball partially out of a radial locating hole on the polygonal coupling rod of the casing to lock the socket being mounted on the polygonal coupling rod of the casing, and a release control rod inserted through a transverse through hole on the ratchet socket wrench coupling portion of the casing and moved to lock/unlock the stop rod, the release control rod having a flank curved outwards on the middle ,the flank being engaged with a recessed top wall of a head at one end of the stop rod when the release control rod is moved to a first position in the transverse through hole on the ratchet socket wrench coupling portion of the casing, enabling the steel ball to be forced out of the radial locating into engagement with the socket mounted on the polygonal coupling rod of the casing, the stop rod being forced forwards by the flank when the release control rod is moved to second position in the transverse through hole on the ratchet socket wrench coupling portion, thereby causing the steel ball to fall in the radial locating hole away from the socket mounted on the polygonal coupling rod.
