ABSTRACT:
An adjustable fitting ring structure includes a connecting base, a fitting ring, a guiding part, and an adjustable part. The connecting base has a receiving slot. There's a plurality of concave wedged slots on the receiving slot. The end portions respectively pass through the connecting base and each have a long slot. A gear portion is located in the long slot. The guiding part includes a base portion, a gear, and a plurality of flexible arms. Each of the flexible arms has a wedged body that contacts the wedged slot. The adjustable part is pivoted with the base portion to make the guiding part rotate so that the two end portions move in the same direction or in different directions. Thereby, the dimension of the fitting ring can be adjusted. It is easy for users to adjust the fitting ring. The structure is simplified and the assembly process is simple.
