ABSTRACT:
In an angularly adjustable, releasably lockable ball joint, the ball has a surface covered with regular polygonal patterns of spaced-apart protrusions. The protrusions each define a concavity. An actuator tip is provided to penetrate the concavity and simultaneously contact all of the protuberances of the pattern to lock the ball and actuator together, thereby fixing the orientation of shanks attached to the ball and actuator.
