ABSTRACT:
A socket includes a main body including a first cylinder having an outer periphery formed with a plurality of outer teeth, and a second cylinder having an inner periphery formed with a plurality of inner teeth. The inner teeth of the main body and the outer teeth of the main body have the same tooth number and have the corresponding tooth shape. Thus, the sockets can co-operate with each other to increase the working length, and the sockets co-operating with the ratchet wrench can be used in an elongated shallower space.
