Abstract

The invention discloses an automatic pencil with a myopia prevention voice prompt function. The automatic pencil comprises a pencil head, a voice broadcaster, a first electromagnet and a distance sensor, wherein a pencil point is arranged at the bottom end of the pencil head; second electromagnets are arranged on the two sides of the distance sensor at the top end of a battery pack; third springsare arranged on one sides of the second electromagnets; and second damping parts are arranged in the two sides of an upper housing on one sides of the third springs. According to the automatic pencil,sealing plates are arranged in the two sides of a pencil body below a first limiting groove, pressing pieces are arranged on one sides of the sealing plates, cavities are formed in the sealing plates, air bags are arranged in the cavities, fourth springs are uniformly arranged between the inner walls of the two sides of the air bags, stop rods are arranged on the two sides of the air bags, suckers are arranged on one sides of the air bags, and one sides of the suckers extend to one sides of the interiors of the pressing pieces. According to the structure, the mechanical pencil can be prevented from falling off when being used, and the service life of the mechanical pencil can be prolonged.

Description

technical field [0001] The invention relates to the technical field of a mechanical pencil, in particular to a mechanical pencil with a voice prompt function for preventing myopia. Background technique [0002] Many primary school students use mechanical pencils to do homework, and when primary school students do homework for too long, their eyes will become tired, that is, they will gradually get closer to the objects, and over time they will form myopia, which is not conducive to the healthy growth of students; [0003] Moreover, the existing mechanical pencils do not have the function of preventing myopia. Incorrect sitting posture for a long time can easily lead to myopia in students. function, the pencil is easily damaged. Contents of the invention [0004] The purpose of the present invention is to provide a mechanical pencil with an anti-myopia voice prompt function, to solve the above-mentioned background technology that does not have the function of anti-myopia, ...
