Pen capable of automatically retracting refill during falling

Abstract

The invention discloses a pen capable of automatically retracting a refill during falling. The pen capable of automatically retracting the refill during falling comprises a pen clip, a pen holder, therefill, a pen point, a linkage component, a balance weight, a spring I and a spring II, wherein the linkage component, the balance weight, the spring I and the spring II are arranged in the pen holder; an outer flange is arranged on the circumferential surface of the bottom of the refill, the spring II sleeves the refill which is located below the outer flange, a cylindrical boss is arranged on the upper end surface of the pen point, and a through hole used for allowing the refill to penetrate through is formed in the middle of the cylindrical boss; the spring I is fixed into a pen body, andthe balance weight is connected to the upper end of the spring I; and a hole is formed in the upper part of the pen holder and used for supporting and limiting the linkage component, an inclined surface is formed at the bottom of the linkage component which is located in the pen holder; and the inclined surface is used for making contact with the top end of the balance weight. According to the pencapable of automatically retracting the refill during falling, the special linkage component is adopted, and the balance weight and the springs are added on the basis of a general pen structure; andthe function of automatically retracting the refill during the falling of the pen, and the function of retracting the refill during shaking for the pen are realized on the basis of general ball-pointpen functions.

Description

technical field [0001] The invention belongs to the field of stationery, and in particular relates to a pen that automatically returns to the core when it falls. Background technique [0002] Pens are necessities that accompany people’s daily life, but the nibs of most rollerball pens and fountain pens on the market today are relatively fragile, and they are generally prone to breakage, especially for groups such as students who have a high demand for pens. Bad pens are more frequent. And a rollerball pen with a damaged nib will be difficult to write normally, and cannot continue to use the remaining ink, and may even make the user face a situation where there is no pen available. Therefore, how to reduce the chance of accidentally breaking the pen is an urgent problem to be solved. [0003] At present, there are many solutions to the accidental drop damage of pens at home and abroad from various aspects, but there are few solutions similar to the principles of this projec...
