AI Technical Summary
学生的不良读写姿势主要受两个原因的影响：一是学生本身的坐姿和读写习惯，二是桌椅与学生身体的不匹配因素，由于传统的学生桌椅一般只具备高度的调节和桌面倾斜角度的调节两种功能，即通过调节桌椅不同的高度和桌面的倾斜角度来适配学生的正常坐姿高度，使学生在读写时比较舒适，但这类学生桌椅并不能规范读写的标准姿势也没有任何提示在什么时候需要调高，若长时间使用仍会造成上述如近视、腰椎、颈椎等疾病的发生，教师、家长、学生虽然都知道正确姿势的重要性，但是由于传统桌椅缺失规范读写姿势的功能，学生自己又很难坚持住正确的读写姿势，致使大多数学生的坐姿、读姿、写字、握笔姿势、运笔姿势等错误的不良习惯无法被及时纠正，严重地影响了学生的学习效率和身心健康
[0015] The beneficial effects of this utility model after adopting the above structure are as follows: First, because the structure of the left and right hand restraint device restricts the position and movement of the student's hands, the student cannot lie on the table or tilt the table to write, which effectively corrects the reading and writing posture; Second, because the reading and writing table adopts a sliding structure on the table that can achieve any direction and path, it ensures that the reading and writing position can be changed even when the left and right arms cannot move. By moving the reading and writing table with the left hand, the writing position is sent to the right hand pen, which meets the requirement of writing quickly without stopping the right hand, improving the student's left and right hand coordination ability and comprehensively developing both hemispheres of the brain.

Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of reading and writing posture correction equipment, specifically relating to an auxiliary table structure for standardizing reading and writing posture. Background Technology
[0002] Poor reading and writing posture among students is a major contributing factor to myopia, lumbar spine problems, cervical spine issues, and other ailments, seriously impacting the healthy growth of adolescents. Poor reading and writing posture is primarily influenced by two factors: firstly, the student's own sitting posture and reading / writing habits; and secondly, the mismatch between the desk / chair and the student's body. Traditional student desks and chairs generally only offer height and tilt adjustment functions. While these adjustments are intended to accommodate a student's normal sitting posture and make reading and writing more comfortable, they do not provide guidance on proper posture or when to adjust the height. Prolonged use of these desks and chairs can still lead to the aforementioned problems such as myopia, lumbar spine issues, and cervical spine problems. Although teachers, parents, and students all understand the importance of correct posture, the lack of posture-correcting features in traditional desks and chairs, coupled with the difficulty students themselves maintain correct posture, means that many students' incorrect sitting, reading, writing, pen-holding, and pen-movement postures cannot be corrected in time, severely affecting their learning efficiency and physical and mental health. Therefore, the industry urgently needs an auxiliary desk that can standardize students' reading and writing posture to help them develop good habits of standard reading and writing posture and eradicate bad reading and writing posture at the source.
[0003] In view of the aforementioned problems, it is necessary to design an auxiliary table structure that is simple in structure and low in cost. This structure allows students to move the writing surface with their left hand to their right hand to write without pausing, thereby improving hand-eye coordination and effectively stimulating the comprehensive development of both hemispheres of the brain. Furthermore, it can regulate the position and angle of students' hands, forcing them to correct their reading and writing posture. Therefore, the applicant has ingeniously designed this technical solution. Utility Model Content

[0029] Please continue reading. Figures 1-3 When reading and writing assignments are required, the book is placed on the aforementioned reading and writing table 2 and aligned using the grid 21. The aforementioned left-hand restraint device 5 and right-hand restraint device 6 are adjusted to an appropriate hand spacing along the left and right directions of the table 1 using the left-hand restraint device claw 51 and right-hand restraint device 61, respectively. Then, the forearms are placed into the aforementioned left-hand support 52 and right-hand support 62. If the arms cannot be placed stably and pressed against the aforementioned left-hand support 52 and right-hand support 62, it indicates that the height of the table and chair is not suitable, and the height of the aforementioned table adjustment support mechanism 7 needs to be adjusted. At this time, the student cannot lean towards the reading and writing table 2 because the arms are restrained by the aforementioned left-hand support 52 and right-hand support 62, thus forcing the student to maintain a standard reading and writing posture. During the reading and writing process, the students can slide the book, i.e., the reading and writing table 2, with both hands, so that the students can change the reading and writing position of the book without moving their arms. That is, when writing, the left hand moves the reading and writing table to promptly send the writing position to the right hand pen to achieve uninterrupted writing, thereby improving the students' left and right hand coordination ability and comprehensively developing both hemispheres of the brain.
