Abstract
A pivot joint having a housing member with a pair of opposing coaxially aligned bores in communication with an elongated channel transverse to the bores. A cylindrical member extends across the channel and rotates within the bores. The cylindrical member is longitudinally split to form a pair of clamping sections having a double-D configuration. A passageway is formed through the cylindrical member transverse to its axis and spanning across the split to define opposing concave bearing surfaces for receiving an axially adjustable rod therethrough. A locking clamp extends into the housing for locking the clamp sections together in a desired rotational orientation within the bores, thereby securely clamping the rod in a desired angular orientation as well as in a desired axial extension.
