Abstract: A movable ball-shape connector for a lighting fixture includes a movable rod, a spherical body, a fix cup, a press block, a spring, and an adjusting block. The spring is disposed between the spherical body and the adjusting block, to produce an elastic force acting upward. And that is used to produce the force to press the spherical body to stay between the movable rod and the fix cup, to fix the spherical body to a certain angle after rotation. Meanwhile, the adjusting block can be rotated, to make it move upward or downward, to adjust the force of the spring pressing against the spherical body, in achieving the objective of fixing the spherical body to a certain angle after rotation.
