Patent ID: 7000301

Claim:
A socket driving device, comprising: a first member having a longitudinally disposed driving shaft formed of a durable, rigid material and configured to have a striking surface end and a distally located mounting end; the striking surface end having a first lateral cross-sectional area and the mounting end having a second lateral cross-sectional area that is substantially the same as the first lateral cross-sectional area; a first coupling protrusion extending from the mounting end, the first coupling protrusion being substantially square in lateral cross-section; a second member having a receiving end that is configured to releaseably receive the mounting end of the first member and a distally located socket-mounting end, the first member being longer in the longitudinal dimension than the second member in that same dimension; the receiving end having a third lateral cross-sectional area and the socket-mounting end having a fourth lateral cross-sectional area, wherein the fourth lateral cross-sectional area is greater than the third lateral cross-sectional area and the lateral cross-sectional area of the second member expands from the third cross-sectional area to the fourth cross-sectional area; and a second coupling protrusion extending from the socket-mounting end, the second coupling protrusion being substantially square in lateral cross-section.
