[0002] Wrong writing posture will have a great impact on children's body and learning. Therefore, helping children correct their writing posture is an important task for parents and teachers. Therefore, parents usually buy correctors to help their children correct their writing posture. However, the common correctors in our lives still have some difficult-to-solve problems: 1. Ordinary correctors usually use the device's own correction force to forcibly correct without a prompt function. They are not intelligent enough and are not convenient enough during learning, requiring parental supervision; 2. Ordinary correctors are used independently and use elastic materials to pull the wrist. They are not intelligent enough and are uncomfortable to use, which can easily cause children's rebellious psychology. Utility Model Content
