Multifunctional adjustable anti-myopia clamp

Abstract

The invention belongs to the technical field of anti-myopia application, and particularly discloses a multifunctional adjustable anti-myopia clamp which consists of a positioning support component, alifting adjusting component matched with the positioning support component and a limit component matched with the lifting adjusting component. The clamp has the advantages that the design is reasonable, the height can be adjusted according to the requirements when in use, the positioning is firm and stable after adjustment, and meanwhile, the intelligent monitoring operation can be realized, for example, when a student does homework, remote supervisory can be realized through a pressure sensor, a data transmit-receive unit and a voice video communication unit. Timely supervision and self-control can be realized through the pressure sensor, a liquid crystal display screen, the data transmit-receive unit, a warning unit, the voice video communication unit and a single chip computer structure, high-efficiency illumination is realized through an added power supply and a lighting lamp structure. A rectangular frame, two groups of abacus bead positioning rods, a plurality of abacus beads anda rectangular standard plate structure are provided, so that the learning calculation is carried out when the student does homework.

Description

technical field [0001] The invention belongs to the technical field of anti-myopia application, and in particular relates to a multifunctional adjustable anti-myopia clamp, which is suitable for being installed on desks or workbenches, etc., so as to prevent users from appearing myopia, and is convenient for adaptive height adjustment. Easy to use, safe and reliable. Background technique [0002] In the relaxed state of accommodation, parallel rays of light are focused in front of the retina after passing through the refractive system of the eyeball, which is called myopia. Myopia is also called short-sightedness, because this kind of eye can only see near but not far. When this kind of eye is resting, the parallel light from infinity is refracted by the refractive system of the eye, and then gathers into a focus in front of the retina. On the retina, unclear images are formed, and the distance vision is significantly reduced, but the near vision is still normal. [0003] ...

AI Technical Summary

Problems solved by technology

[0005] The hazards of myopia: (1) Delay in learning - put in 30% more effort, blurred vision, dry and sore eyes, difficulty in concentrating, emotional irritability and even dizziness caused by myopia will make children pay more than children with normal vision 30% of the time and mental work, spending longer time on study; (2) dragging down the entrance examination - more than 30 majors are restricted from applying for the exam, and a large number of candidates are rejected every year because of myopia. It involves nearly 30 majors such as electronic information, bioengineering, medical pharmacy, aviation, and navigation technology, which seriously affects children's life and career planning, etc.
