Description

Technical Field

[0001] This utility model belongs to the field of jewelry technology, and in particular relates to an open bracelet with an outward-pulling and rotating flaring design. Background Technology

[0002] Bracelets, as jewelry accessories carrying profound cultural connotations and fashionable charm, occupy an important place in people's daily lives. Open bracelets, with their relatively flexible wearing method, do not require precise matching of wrist circumference compared to closed bracelets, avoiding problems such as difficulty in wearing due to size errors or easy slippage due to being too loose, and are therefore highly favored by consumers. However, there are still many problems to be solved in the wearing and removing processes of currently mainstream open bracelets.

[0003] Most existing open bracelets rely solely on the bracelet's own elastic deformation for adjustment. These bracelets are usually made of a metal with a certain degree of flexibility. When wearing them, the user needs to forcefully pry open the sides of the bracelet to create elastic deformation, thereby widening the opening to fit the wrist; when removing them, the same reverse force is required to narrow the opening. This method requires a relatively high level of hand strength from the user. For people with less strength, such as women, children, or elderly people with weak hand strength, it is often difficult to complete the putting on or taking off the bracelet independently, and they may even need the help of others, causing great inconvenience in daily use.

[0004] Furthermore, frequent bending and twisting of the bracelet can cause fatigue damage to the metal material. With increased use, the bracelet's elasticity gradually weakens, and irreversible deformation can easily occur at the opening, leading to an overall distorted shape. This not only affects its appearance but may also prevent it from fitting snugly against the wrist, making it prone to wobbling or slipping during wear and increasing the risk of loss. Additionally, uneven or excessive force during bending can cause scratches, dents, and other imperfections on the bracelet's surface, severely impacting its quality and value.

[0005] Therefore, the inventors dedicated themselves to designing a bracelet to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide an open bracelet with an outwardly pulling and rotating flared opening, which allows for easy adjustment of the bracelet's opening, ensuring the bracelet's structural stability and durability during the adjustment process, and avoiding damage caused by frequent deformation.
