In another embodiment, the hollow collar 201 is model RB15013UU, with dimensions of 180mm for the outer ring and 150mm for the inner ring, with a rotational accuracy of 5 μm.

The spray head module adjusting device provided by the embodiment adopts the precise hollow shaft collar 201 as the core component of the spray head module rotating device, thereby not only ensuring the motion precision requirement of the mechanism, but also ensuring the overall structure to be simpler and more compact.
