One end of the second arm member is pivotably mounted on the bracket member for rotation about a selected axis while the opposite end is connected to another bracket member for rotation about an axis that extends transverse to the axis of rotation of the first bracket member; the second bracket member is connected to a third arm member which includes a single clamping device for a ball rotatably carried in a ocket to which a mounting pin is attached.
