<p>A socket wrench (10) is shown having a socket driver head (12) pinned to a clevis (32) on a shaft (30). A sleeve (60) is receivable over the shaft end and includes open ended slots (72) pointing away from the clevis. The shaft includes a pin (20, 52) press fit within a cross bore (44, 50) on the shaft end, and the shaft and sleeve are axially slidable relative to each other; where in one position the pin engages one of the slots, and in another position, the shaft and sleeve spin freely of each other. A handle (80) includes an internal bore (82) which is profiled to compressively fit over the sleeve, and a chamber (84) is defined between the sleeve and the end (88) of the internal bore, to provide clearance for the axial movement of the shaft and sleeve.</p> |
