[0008] According to the auxiliary device for preventing myopia among primary and secondary school students, the moving rod is fixedly connected to the mounting column by a fixing bolt.

[0009] According to the auxiliary device for preventing myopia among primary and secondary school students, a protective sleeve is provided on the outer surface of the limiting rod.

[0010] The purpose of the utility model is to provide an auxiliary device for preventing myopia among primary and secondary school students. The main innovative features are:

[0011] The auxiliary device for preventing myopia among primary and secondary school students blocks students by setting installation columns, moving rods, threaded holes, fixing bolts and limiting rods to prevent them from getting close to study tables. By installing a shell, a probe and a buzzer, when a student's head is too close to the table, the buzzer will sound an alarm to remind the student, thereby achieving the purpose of preventing myopia.

[0012] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0020] Reference Figure 1-3 The utility model embodiment is an auxiliary device for preventing myopia in primary and secondary school students, which includes a desktop 1, a desktop body 2 is fixedly connected to the lower end of the desktop 1, an electric push rod 3 is arranged inside the desktop 1, a mounting shell 4 is fixedly connected to one side of the electric push rod 3, a probe 5 is arranged on the upper end of the mounting shell 4, and a buzzer 6 is arranged on one side of the mounting shell 4. Through the mounting shell 4, the probe 5, and the buzzer 6, when the student's head is too close to the desktop 1, the buzzer 6 will sound an alarm to remind the student, thereby achieving the purpose of preventing myopia;

[0021] Both sides of the table body 2 are fixedly connected with mounting columns 7, and moving rods 8 are slidably arranged inside the two mounting columns 7. One side of the two mounting columns 7 is threadedly connected with fixing bolts 10, and one side of the two moving rods 8 is provided with a plurality of threaded holes 9, and one side of the two moving rods 8 is fixedly connected with a limiting rod 11.
