Positioning automatic pencil of primary school equipment

Abstract

The invention discloses a mechanical pencil with positioning for primary school students, which includes a pen point, a pen head and a pen holder. One side of the pen point is provided with a pen head. The bottom of the pen core tube is sleeved with a spring, the inside of the penholder is provided with a shock absorbing layer, one side of the shock absorbing layer is fixed with a GPS positioning module, one side of the GPS positioning module is provided with a button battery, and the penholder There is a charging jack on one side, and a display screen on one side of the charging jack. The charging jack is equipped with a dust-proof plug, and a lighting lamp is fixed on the outside of the pen holder. The lighting lamp is electrically connected to a switch button. Connected with a sleeve, the top of the sleeve is fixed with a pressing block, and the GPS positioning module, charging jack, lighting, display screen and button battery are electrically connected. Through the shock-absorbing layer set, the vibration generated when the mechanical pencil falls is reduced, the refill and the pen barrel are protected, and the service life of the mechanical pencil is extended.

Description

technical field [0001] The invention relates to the technical field of supplies for primary school students, in particular to a mechanical pencil with positioning for primary school students. Background technique [0002] Mechanical pencils are divided into thick core (greater than 0.9mm) and thin core (less than 0.9mm) mechanical pencils according to the diameter of the pencil core. According to the way of core out, it can be divided into drop core type, rotary type, pulse type and automatic compensation type. The mechanical pencil needs to be put into a thin refill made of graphite (commonly known as a lead lead) before use. After putting the refill, close the cover at the back to prevent the refill from falling out. There is a spring in the mechanical pencil, and pressing the cover at the back can make the refill stick out from the front end at a fixed length, and write fonts with the same thickness. In order to maintain smooth writing, wooden pencils need to be curled ...

AI Technical Summary

Problems solved by technology

[0003] Existing pencils are made of wood and are not environmentally friendly. When sharpening pencils, primary school students are likely to injure their fingers, which is very dangerous. Mechanical pencils are all plastic shells, which are easy to damage the refill and pencil when dropped, reducing the service life. Now primary school students Abduction incidents are prone to occur, and real-time positioning of primary school students is required. The existing mechanical pencil has a simple structure and a single function
