Technical Field

[0001] This utility model relates to the technical field of sitting posture detection devices, specifically an adjustable sitting posture detection device. Background Technology

[0002] Many children today have poor reading postures and habits, making them prone to nearsightedness, hunchback, and even cervical spine problems. Therefore, a device that can detect sitting posture is needed to prevent children from sitting too close to their desks, which can lead to these issues. Existing posture detection devices are generally fixed in place, making them inconvenient to adjust according to the desk, body type, and sitting position, resulting in inaccurate detection. For example, patent number CN105844866B discloses a posture detection device where the distance measuring detector is fixedly mounted on the computer screen to calculate distance and cannot be adjusted according to the situation. Therefore, an adjustable posture detection device is needed. Utility Model Content
