[0003] In the existing ear vagus nerve electric stimulation device, for example, the ear vagus nerve electric stimulation device disclosed in Chinese patent CN219071829U points out that the device disclosed in another Chinese patent CN210020867U has structural limitations and cannot adapt to the neck sizes of different people. Therefore, CN219071829U proposes a solution by pulling two installation shells respectively to make the limiting grooves extrude the limiting rods, and the limiting plates compress the springs, so that one end of the limiting rods is displaced under the next limiting groove. When the spring is no longer compressed, the limiting plate will push the limiting rod into the limiting groove, thereby realizing the adaptation to different thick and thin necks.

[0004] However, although the above improvement solves the problem of neck size adaptability, there is still a problem of wire fixation and storage. According to the description in CN219071829U, the fixation of the wire is achieved by folding and storing through a simple fixing sleeve, but this way is easy to cause the wire to be rolled up in disorder, affecting the subsequent use process.
