Description

Pen

Technical Field

The invention belongs to the field of stationery commodities, and particularly relates to a pen.

Background

The pen is one of the common writing tools used by people in daily study and work, is popular, but is often troublesome or problematic, when the pen is required to be used, people can suddenly find that the pen cannot write out a word without ink or cannot write a word suddenly in the writing process, people know that the pen does not have ink, if the pen does not have ink at the moment, the trouble is great, if the pen stores spare ink, the trouble can be solved in the critical moment.

When the pen is used for writing, the pen can quickly discharge ink when the pen is filled with ink for writing, particularly when the pen is applied to paper with good ink absorption, the written handwriting of the written character is too thick and even difficult to control, and a large ink dot appears when the pen is slightly stopped on the paper, so that the writing effect and the writing experience are directly influenced.

When the pen is placed in a clothes pocket, the pen cap and the pen holder can be prevented from falling off, particularly when the pen cap is hung in the clothes pocket by using the hook on the pen cap, the pen cap and the pen holder can be frequently fallen off, once the pen cap and the pen holder fall off, the pen point is directly contacted with clothes, at the moment, ink can slowly seep onto the clothes along the pen point, when the clothes are found, the clothes are dyed into a piece of ink, and the ink is extremely difficult to clean.

The laser indicator is frequently used in teaching, training, meetings and the like, can quickly indicate and position a certain target in a certain range, is very convenient, a pen as a common tool can be frequently carried about, the laser indicator is rarely carried about, and the laser indicator is good if the laser indicator can be integrated on the pen; and nowadays, pen users are more students, and the vision safety protection of students and the like is considered, so that the laser emitted by the laser indicator is better without causing harm to the users.
