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.

[ I claim:] [1.] A quick-release socket adapter comprising a 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 steel ball moved in and out of a radial locating hole on said polygonal coupling rod for securing the socket mounted on said polygonal coupling rod, a spring mounted inside said casing, a stop rod inserted into said hollow ratchet socket wrench coupling portion and said hollow polygonal coupling rod and forced by said spring to push said steel ball out of said radial locating hole into engagement with the socket mounted on said polygonal coupling rod of said casing, and a release control rod controlled to release said stop rod from said steel ball, enabling said steel ball to fall into the inside of said radial locating hole and to disengage from the socket mounted on said polygonal coupling rod, wherein said hollow ratchet socket wrench coupling portion of said casing has a transverse through hole, said transverse through hole having two sections of different diameters; said stop rod has a head at one end moved with said stop rod in said hollow ratchet socket wrench coupling portion; said spring is mounted around said stop rod and stopped between the head of said stop rod and an inside step between said hollow ratchet socket wrench coupling portion and said hollow polygonal coupling rod; said release control rod is inserted in said transverse through hole on said hollow ratchet socket wrench coupling portion, said release control rod having a flank on a middle thereof moved with said release control rod in said transverse through hole between a first position where the head of said stop rod is forced by said spring into engagement with said flank and said steel ball is partially forced out of said radial locating hole by said stop rod, and a second position where the flank of said release control rod forces a part of the head of said stop rod forwards, causing said spring to be compressed and said steel ball to fall in said radial locating hole away from the socket mounted on said polygonal coupling rod.
