Ring accessory, a ring head structure and a ring

A ring head structure, comprising:

• a ring accessory having:
• an outer loop and an elastic piece;
• the elastic piece is placed within the outer loop;
• the outer loop comprises a lateral loop and a top cover located above the lateral loop;
• the top cover has a hole configured for a ring head passing therethrough, an inner side of the top cover comprises at least three deep recesses at an edge of the hole, and a shallow recess is provided between every two adjacent deep recesses, wherein a distance from each deep recess to the center of the hole is greater than a distance from the shallow recess to the center of the hole;
• the elastic piece comprises elastic piece deep recesses and elastic piece shallow recesses respectively corresponding to the deep recesses and the shallow recesses of the top cover, wherein the elastic piece is an annulus with a wave shape, with the elastic piece deep recesses being located at a bottom of the wave and the elastic piece shallow recesses being located at a top of the wave;
• and
• a ring support;
• wherein the ring support comprises a support rod;
• the support rod comprises a distal end located at an upper portion thereof, and a distance from the distal end to a symmetry center of the ring support is no greater than a distance from the deep recess to the center of the hole.

A ring, comprising:

• a ring body and a ring support located at the ring body, wherein the ring further comprises a ring head including a ring accessory having:
• an outer loop and an elastic piece;
• the elastic piece is placed within the outer loop;
• the outer loop comprises a lateral loop and a top cover located above the lateral loop;
• the top cover has a hole configured for a ring head passing therethrough, an inner side of the top cover comprises at least three deep recesses at an edge of the hole, and a shallow recess is provided between every two adjacent deep recesses, wherein a distance from each deep recess to a center of the hole is greater than a distance from the shallow recess to the center of the hole;
• the elastic piece comprises elastic piece deep recesses and elastic piece shallow recesses respectively corresponding to the deep recesses and the shallow recesses of the top cover, wherein the elastic piece is an annulus with a wave shape, with the elastic piece deep recesses being located at a bottom of the wave and the elastic piece shallow recesses being located at a top of the wave;
• and
• wherein the ring support comprises a support rod;
• the support rod comprises a distal end located at an upper portion thereof, and a distance from the distal end to the symmetry center of the ring support is no greater than a distance from the deep recess to the center of the hole;
• wherein the support rod further comprises a proximal end located at a lower portion thereof, a distance from the proximal end to the symmetry center of the ring support is smaller than a distance from the distal end to the symmetry center of the ring support, and a distance from the proximal end to the symmetry center of the ring support is no greater than a distance from a shallow recess to the center of the hole, with a transition portion arranged between the distal end and the proximal end of the support rod;
• the outer loop is held onto the ring support, with the top cover of the outer loop being exposed at the upper portion of the support rod;
• the transition portion is located at a position of the shallow recess and is in close contact with the elastic piece shallow recesses of the elastic piece.
