ABSTRACT:
A socket tool includes a handle and a socket is movably mounted to one of two ends of the handle. A groove and a plurality of notches are defined in the outer periphery of the end of the handle. The socket has two passages defined through a wall of the socket and an angel is defined between each one of the passages and a radius of the socket. A positioning pin extends through the wall of the socket and is engaged with the groove of the handle. The two passages are located at two different longitudinal positions from an end of the socket. A bead and a spring are respectively received in each of the passages, and one of the two beads is engaged with one of the notches by moving the socket on the end of the handle. Each of the two beads engaged with the notch decides the direction that the socket drives an object accommodated in the socket.
