The groove width of the moving ring is limited, and the ring can't shrink again after it shrinks to a certain extent. If forced to shrink again, the outer ring and the inner ring of the ring will not stick together, and there is a gap between the inner ring and the outer ring, which is easy to get stuck in the hair, or hang it somewhere, and pull the ring out of shape. You can refer to the following methods for debugging:

1, it's easy to adjust if you have a ring stick. Put the ring on the ring stick and wear it as many times as you want. Just determine the number of laps.

2. If not, just put it on your hand and adjust it yourself. When wearing it on your hand, first press the inner part of the ring to a suitable position, then press the outer part of the trap to a suitable position, and pay attention to fixing it after adjusting the size, otherwise it will be easy to loosen.

3. If you can't adjust the size of the movable ring by yourself, you'd better go to a jewelry store or a processing shop and adjust the lower ring with a special tool-the ring bar, so that it won't be deformed. If you adjust yourself, you can use a round hard object or adjust it, but the tools are hard to find, so you'd better go to specialty store.
