Patent ID: 8667871

Claim:
A telescoping extension tool comprising: a retention housing having a retention sleeve that is generally hexagonally shaped and has a generally hexagonal opening substantially aligned with the longitudinal axis of the retention sleeve, wherein the retention sleeve further comprises a retainer mounted therein such that the retainer tends to retain the extendable portion within the retention sleeve, and wherein the retention sleeve has a square opening at one end of the retention sleeve that is sized and configured to fit a standard socket wrench drive element; an extendable portion having a substantially hexagonal shape wherein the extendable portion is capable of being engagingly inserted into the hexagonal opening of the retention sleeve to be substantially retained within the retention housing such that the extendable portion can be one of either inserted into or extend from the retention sleeve to allow a socket mounted onto the extendable portion to access a fastener; and a cap having a set of internal threads that match a set of external threads on the retention sleeve such that tightening of the cap compresses the retainer to deform a hexagonal opening in the retainer to adjust the grip the retainer has on the extendable portion.
