瓶子逆變器

I am not familiar with the official name of this mechanical system; some refer to it as a 'bottle inverter,' while othe use the term 'bottle turner.' I designed this system after watching a video on YouTube that showcased its simple yet impressive functionality. One notable advantage of this mechanical system is the absence of moving or rotating parts, leading to reduced maintenance requirements. The system I created facilitates a 180-degree rotation, and I am aware that some individuals have developed variants offering 90 and 360-degree rotatio as well.
