Patent ID: 7628382

Claim:
A hand tool, comprising: a first member having two extensions each extending longitudinally in a substantially parallel manner from a first end of the first member; an indexable coupling mechanism; a second member having one extension extending longitudinally from a first end of the second member; the two extensions of the first member being coupled to the one extension of the second member using the indexable coupling mechanism; wherein: each of the two extensions of the first member having a receptacle with a splined inner circumference thereof, the extension of the second member having a receptacle with a splined inner circumference thereof; the indexable coupling mechanism including a splined pin assembly, the splined receptacles adapted to receive the axially aligned splined pin assembly therein, the indexable coupling mechanism adapted to couple the first member and the second member so as to permit the first member to be pivoted, indexed and locked with respect to the second member, further wherein the splined pin assembly further comprises: a splined pin having a first, square cut around a circumference of the splined pin commencing at the edge of the splined pin, a second v-groove cut around a circumference of the splined pin and longitudinally located between the middle and ⅓ to the edge of the splined pin, and a third square cut around the circumference of the pin near the edge of the pin opposite the first square cut, and a threaded bore centered at the ends of the splined pin; a first retaining cap being a circular planar member having a centered, smooth tapered bore there-though; a first screw with a tapered head to be disposed through the first retaining cap to couple the first retaining cap, via the first screw, with one end of the threaded bore of the splined pin; a semi-rigid circular wire to be disposed around the splined pin about the v-groove of the splined pin; a second retaining cap being a circular planar member having a centered, smooth tapered bore there-though; and a second screw with a tapered head to be disposed through the second retaining cap to couple the second retaining cap via the second screw with the other threaded bore of the splined pin.
