Adjustable Car Bottle Holder

A fully adjustable car bottle holder designed to fit a wide range of vehicle cup holders and beverage containers.
The design features two independent adjustment mechanisms:
Lower module securely expands inside the vehicle's cup holder, adapting to different diameters and providing a stable, vibration-resistant fit.
Upper module adjusts to grip bottles, cups, and travel mugs of various sizes, from small water bottles to large reusable containers.

The mechanism uses a spiral cam system with three sliding jaws, providing smooth and synchronized movement without the need for springs. Each module can be adjusted independently and locked in position using a threaded locking ring, preventing loosening during driving.
