Background Various magnetic rings are widely used in the household appliance industry, and are generally used for shielding electromagnetic interference of equipment, so that electromagnetic compatibility of products is improved. Magnetic ring structures commonly used in the industry are circular closed versions and snap-in semi-closed versions. The method for fixing the magnetic ring generally depends on the structure of the position to make corresponding structural features and fasteners to achieve the fixing purpose, such as a buckle structure, a fixed slot structure, a wire bundle and the like, but has the following disadvantages: 1. The above various structural features (such as the buckle structure, the fixed slot structure and the like) have special properties, the application range is limited, the application is inconvenient, the fixing mode of the adjusting magnetic ring or the changing of the magnetic ring can lead to the change of the structural features, the adjusted or changed magnetic ring is not stably fixed by the original buckle and fixed slot structure, the die is required to be changed again, and the cost is wasted. 2. Although the wire bundle fixing mode is not limited by the structure, redundant tail parts need to be cut off after the magnetic ring is fixed, and the wire bundle is only bound at one time and is effective. On one hand, the wire bundle can not be reused, on the other hand, the tail cutting procedure is complicated, the production efficiency is low, and the problems of sharp scratch of the tail, wiring, pipe fittings, components and the like exist. 3.
