CNC Aluminium Folding Arm Joint Fitting (suit for D30mm Tube)

Note:
The difference between the two editions is that, the auto-folding edition, you can bend it with hand directly to fold and unfold it, it DOES NOT mean it can fold/ unfold itself. Yet for the hand-driven edition, you have to remove and reinstall the screws before you can fold and unfold it.
