Technical Field

[0001] The utility model relates to a student tool, in particular to a device for correcting students' sitting posture, protecting students' eyesight and promoting the normal growth of students' bones. Background Art

[0002] The applicant disclosed a "protective device for correcting students' sitting posture" in CN200420062055.7. The protective device for correcting students' sitting posture includes a base, a limit rotating plate, a sliding seat, a prompt rod, a slide rail and a vibration circuit. The sliding seat is rotatably mounted on the base, the prompt rod is sleeved in the sliding seat, the prompt rod is extendable and retractable relative to the sliding seat, a vibration circuit containing a DC power supply, an electric vibrating plate and a contact switch is provided in the sliding seat, the contact switch is mounted on the sliding seat, and its position corresponds to the protrusion on the limit rotating plate; the limit rotating plate is rotatably mounted on the base and is located behind the sliding seat. When the sliding seat is in a vertical position, the limit rotating plate is located at a position in contact with the sliding seat, at which time it can limit the rotation of the sliding seat, the protrusion on the limit rotating plate corresponds to the contact switch on the sliding seat, and when the limit rotating plate deviates from the sliding seat, the sliding seat can be rotated to a horizontal position, and the base is fixed to the bottom of the desktop by a slide rail and is located in front of the student.

[0003] This device is installed under the desktop. When not in use, the limit rotating plate can be rotated away from the sliding seat, and the combination of the sliding seat and the prompt rod can be retracted and pushed under the desktop. When students are in class, the combination of the sliding seat and the prompt rod can be pulled out from under the desktop to make the sliding seat in a vertical state, and the limit rotating plate can be rotated to a position in contact with the sliding seat. If the student's sitting posture is incorrect, his chest will touch the prompt rod. At this time, the contact switch on the sliding seat is pressed and turned on, and the prompt rod will vibrate under the action of the electric vibration plate to remind the student to correct his sitting posture. No sound will be generated in this process, and it will not affect others, thereby achieving the purpose of correcting students' sitting posture, protecting students' eyesight and promoting students' normal bone growth.

[0004] Although this protective device for correcting students' sitting posture can achieve the expected effect, it must be installed on the desk. In the actual implementation process, students need to follow the prescribed operating requirements and also need to operate according to specific agreements when not in use. Not only is the operation more cumbersome, but it is also inconvenient to use. If used improperly, the prompt rod is easily broken, the damage rate is high, and the service life is not long. It must be improved. Utility Model Content
