The utility model provides a tool for adjusting and expanding ring numbers, which comprises: a size plate 11 and an elastic expander 12. The size board 11 is provided with a plurality of positioning grooves 111 with different set sizes, the positioning grooves 111 are used for positioning and placing the ring 13, the elastic expander 12 is sleeved in the ring 13, the elastic expander 12 comprises a stud 121, a nut 122, tapered columns 123 and an elastic ring 124, the two tapered columns 123 are sleeved on the periphery of the stud 121 in a sliding mode, one ends, smaller in outer diameter, of the two tapered columns 123 are arranged close to each other, the elastic ring 124 is sleeved on the periphery of the two tapered columns 123, the nut 122 is connected to the stud 121 in a threaded mode, and the tapered columns 123 are pressed to slide, so that the tapered columns 123 are pressed by the elastic ring 124 to expand.

Referring to fig. 3, in the present embodiment, the elastic ring 124 is cut and unfolded along the axial direction to form a wavy structure.

Specifically, the elastic ring 124 includes a plurality of axial strips 1241 extending in an axial direction, ends of adjacent axial strips 1241 are connected by connecting strips 1242, and two ends of each axial strip 1241 are respectively connected with an adjacent and different axial strip 1241.

In this embodiment, since the curvature of the inner surfaces of the ring portion and the decorative portion is different, the curvature of the outer periphery of the elastic ring 124 is also different at different positions, and is adapted to the outer peripheral surface of the ring.

Referring to fig. 2 and 3, along the axial direction of the axial strip 1241, the middle portion of the inner wall of the axial strip 1241 is protruded, so that two ends of the inner wall of the axial strip 1241 are inclined surfaces, and the inclined surfaces are adapted to the tapered posts 123.

The elastomeric ring 124 in this embodiment includes a dual number of axial strips 1241. The distance between adjacent axial strips is equal, thereby forming more uniform expansion force on the ring.

In the present utility model, the number of axial bars 1241 may be twelve, fourteen, sixteen, eighteen or twenty. The number of axial bars 1241 is preferably sixteen in this embodiment.

One end of the stud 121 in this embodiment is a screw head, that is, the bottom end of the stud 121 in fig. 2 is provided with a screw head, and a conical column 123 is matched with the screw head in a positioning manner.

Referring to fig. 1, in the present embodiment, an inner side surface of the positioning groove 111 is provided with an arc-shaped groove 112 adapted to an outer peripheral side surface of the ring 13.
