Tap pressurized writing instrument

Abstract

The present invention relates to a knock pressurized writing instrument which has convenience of operation to be used as a writing instrument by exposing and hiding a pen point formed on a lower part of a pen lead to a lower part of a case body axis by making the case body axis ascend and descend on an external case body as a finger bone of one hand holds the external case body, and three fingers easily hold the case body axis combined with the external case body, and increases interest of children about the writing instrument by forming a character figure on both extension units exposed to an upper part of the case body axis.

Description

technical field [0001] The present invention relates to a striking pressurized writing tool, and more specifically relates to holding the outer cylindrical body with the fingers of one hand, and using a plurality of fingers to lift and lower the cylindrical shaft combined with the outer cylindrical body so that the lower part of the cylindrical shaft It is easy to expose the nib formed on the lower part of the refill for use as a writing instrument, and hide the nib formed on the lower part of the barrel shaft to make it easy to store the nib at the lower part of the barrel shaft, and on the outer side of the barrel The two extensions exposed on the upper part are formed with cartoon characters, which can increase children's interest and concern for the writing tool. Background technique [0002] Usually, the knocking type entry and exit structure of the pen core includes: the knob cover, which is provided with a fixed gear for in and out operation in the shaft tube; the rot...

AI Technical Summary

Problems solved by technology

However, in the knock-in and out structure of the above-mentioned pen core, when the lower part of the pen core is exposed to the bottom of the shaft tube as a writing tool, the rotary machine and the pen core are lowered by pressing the knob cover of the shaft tube, A series of knob covers, rotating gears, and elastic springs that compress the coil spring to expose the refill to the outside of the shaft tube are formed in an interlocking manner. Therefore, when one of the knob cover, rotating gear, and elastic spring fails, the pen core will The problem that the tip cannot be exposed to the outside of the shaft tube

And, there are many problems that cannot arouse children's interest and concern in the design of the writing instrument that exposes the tip of the pen core to the outside of the shaft tube as described above.

In addition, there is a problem in the prior art that it is impossible to provide the percussion pressure type writing instrument of the present invention as follows: the outer cylinder body is held between the fingers of one hand, and the cylinder body combined with the outer cylinder body is combined with a plurality of fingers. The shaft lifts to easily expose the nib formed on the lower part of the refill at the lower part of the barrel shaft for use as a writing instrument, and hides the nib formed on the refill at the lower part of the barrel shaft so that it can be easily placed on the lower part of the barrel shaft Keep the pen tip, and the two extensions exposed on the upper part of the outer cylinder form a cartoon character, thereby increasing the convenience of the writing tool's operation, and increasing children's interest and concern for the writing tool
