Technical Field

The invention relates to the technical field of pens for students, in particular to a ball pen for correcting sitting postures.

Background

A ball-point pen is a pen using a minute rotary ball made of brass, steel or tungsten carbide to release ink onto paper at the time of writing, and is generally composed of a pen shaft, a cartridge and a pen tip.

Some students always like carrying the back when writing, and after a long time, eyes are short-sighted and are not beneficial to the healthy development of the spine of the body, so that a ball-point pen for correcting sitting postures is provided.

Disclosure of Invention

The present invention is directed to a ball-point pen for correcting a sitting posture, which solves the above problems of the prior art.

In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a ball-point pen of correcting position of sitting, includes the pen-holder, installs the nib in the pen-holder bottom and installs the refill inside the pen-holder, the top is fixed with the backup pad in the pen-holder, the power is installed to the top of backup pad, the top of power is equipped with control circuit board, the baffle is installed to control circuit board's top, the electron eye is installed on the top of pen-holder, the spring is installed to the bottom of backup pad, the electromagnetism iron plate is installed to the bottom of spring, electromagnetism iron plate bottom center department is equipped with the recess, the below of electromagnetism iron plate is equipped with magnet, magnet is installed at the inner wall of pen-holder.

Preferably, the baffle is provided with a wire guide hole in the center.

Preferably, the through hole is in clearance fit with the pen core, and the groove is in interference fit with the pen core.

Preferably, the bottom of the magnet is provided with a slope.

Preferably, the outer wall of the penholder is fixed with a non-slip mat.

Compared with the prior art, the invention has the beneficial effects that:

1. when the ball-point pen is used, if the electronic eye monitors that the sitting posture of a student is incorrect and the humpback phenomenon occurs, the electronic eye triggers the telescopic mechanism in the pen holder to retract the pen point, so that the pen cannot write, and once the sitting posture is adjusted correctly, the electronic eye can pop up the pen point, so that the humpback phenomenon of the student can be corrected and reduced.
