ABSTRACT:
A knuckle joint in which a first piece with an eye enters a jaw between two corresponding projections of a second piece having a first and a second eye respectively formed therein, and is retained by a pin member, wherein the pin member comprises a pin having a first end with a button fixed thereat and a second end. The pin passes through the eye of the first piece, which then retractably protrudes the button out from the first eye of the second piece and extends the second end to a position near the second eye of the second piece. A stopper has a protrusion which is passed through the second eye of the second piece, extending into the eye of the first piece, and joined with the second end of the pin. A slide block is passed through by the pin and inserted within the eye of the first piece, retractably protruding into the first eye of the second piece. The knuckle joint can be pivotally rotated while the button is depressed to push the protrusion of the stopper out from the eye of the first piece and to push the slide block out from the first eye of the second piece.
