Elastic hard pen capable of adjusting elastic intensity

Abstract

An elastic hard pen whose elastic strength can be adjusted includes a penholder with a section of elastomer (1). An elastic pen core (3) is provided in the penholder and an adjustable rod means (4) is connected to the penholder to adjust the working length for the elastomer in the direction of the axis of the penholder.

Description

technical field [0001] The invention relates to an elastic hard pen with adjustable elastic strength. Background technique [0002] Known elastic hard pen at present is that part or all of the sections of the pen holder from the nib end to the finger holding pen position are made of elastic materials such as rubber and steel wire springs (seeing the patent No. Elastic hard pen"), but the premise that elastic hard pen can write more smoothly, the font is more beautiful, and reduce writing fatigue is: the elastic strength of the pen holder should match the user's writing strength, otherwise, it is okay if it is too hard, and it is right to be ordinary If the hard pen is used, if it is too soft, the strokes will be inaccurate, difficult to control, and even difficult to write; the elastic strength of the pen barrel that matches the user's writing strength varies from person to person. The elastic strength may be just right for some people, but it may be too hard for some peopl...

[0002] Known elastic hard pen at present is that part or all of the sections of the pen holder from the nib end to the finger holding pen position are made of elastic materials such as rubber and steel wire springs (seeing the patent No. Elastic hard pen"), but the premise that elastic hard pen can write more smoothly, the font is more beautiful, and reduce writing fatigue is: the elastic strength of the pen holder should match the user's writing strength, otherwise, it is okay if it is too hard, and it is right to be ordinary If the hard pen is used, if it is too soft, the strokes will be inaccurate, difficult to control, and even difficult to write; the elastic strength of the pen barrel that matches the user's writing strength varies from person to person. The elastic strength may be just right for some people, but it may be too hard for some people, and it is too soft for some people; at the same time, the same user has different requirements for the elastic strength of the pen holder under different writing conditions, and even, Sometimes it is required to convert the elastic hard pen into a normal hard pen with no elasticity in the barrel

Therefore, at this time, the elastic hard pen with a single elastic strength cannot meet the different requirements of different users or the same user for the elastic strength of the pen holder under different writing conditions. People need a kind of elastic hard pen suitable for their writing strength.
