[0002] An orthodontic traction device is a device used to pull the tooth surface during tooth correction.

[0003] At present, there are many orthodontic traction devices on the market, but generally, the traction device of orthodontics is installed by the user directly engaging the traction frame with the calibration chain on the teeth. However, due to the different face shapes of different people, the connection between the traction frame and the calibration chain is very easy to be offset, which causes the traction frame to be installed unstable on the face of the user, resulting in poor traction effect of the device on the teeth and reducing the practicality of the device.

[0004] Based on the above, the inventors found that: the user directly engages the traction frame with the calibration chain on the teeth for installation, but the different face shapes of different people make the connection between the traction frame and the calibration chain very easy to deviate, thereby causing the traction frame to be unstable on the user's face, so that the device has a poor traction effect on the teeth. Therefore, in view of this, the existing structure is studied and improved to provide a traction device for oral orthodontics, in order to achieve a more practical purpose. Utility Model Content
