Self-adjustment roller ball pen shell and roller ball pen

Abstract

The invention relates to a self-adjustment roller ball pen shell adaptable to refills of different lengths and a roller ball pen with the self-adjustment roller ball pen shell. The self-adjustment roller ball pen shell comprises a pen supporting portion and a pen containing portion, wherein the pen supporting portion and the pen containing portion constitute a shell body. An upper supporting pieceand an anti-disengagement sleeve are arranged in the pen containing portion. The upper supporting piece is composed of an upper vertical rod and a lower clamping head. The anti-disengagement sleeve is in a barrel shape with an upward opening. The vertical rod of the upper supporting piece is sleeved with a second spring. The clamping head is contained in the anti-disengagement sleeve. Limiting heads protruding out of the inner wall of the anti-disengagement sleeve are arranged in the anti-disengagement sleeve. The limiting heads conduct resistance above the clamping head. A pen holding platform is fixedly connected with the lower end of the anti-disengagement sleeve. Side supporting pieces and press sleeves are arranged on the two sides of the pen holding platform. The two ends of each press sleeve are sealed, the inner portion of each press sleeve is hollow, and one end of the each press sleeve is provided with a through hole. One end of each side supporting piece is fixedly connected with the side face of the pen holding platform. The other end of each side supporting piece extends into the corresponding press sleeve through the corresponding through hole. The portion, extendinginto the corresponding press sleeve, of each side supporting piece is rodlike and sleeved with a first spring.

Description

technical field [0001] The invention relates to the technical field of stationery, in particular to a self-adjusting gel pen shell that can adapt to pen cores of different lengths, and a gel pen using the self-adjusting gel pen shell. Background technique [0002] As social attention has shifted from electronic input to handwriting input, the usage and sales of gel pens have once again ushered in a good situation. Because the existing education can not fully cover the electronic, writing is still the most important text input method for students. Moreover, a person's writing level also reflects a person's personality, so handwriting is still irreplaceable in daily life. my country has obvious advantages and a broad market in the design and production of gel pen shells. With the help of China's abundant cheap labor force and a large number of designers with novel design ideas, the types of gel pen shells are also increasing. . However, the following problems exist in the ex...

Problems solved by technology

However, the following problems exist in the existing market. Because most gel pen shells are not disposable consumables, although the integrated disposable gel pen is easy to use, its cost and price cannot be accepted by consumers. Accept, so most consumers still use gel pens with multiple refills in one shell, but because the refills produced by different manufacturers on the market cannot perfectly match the shells of consumers who are not from this manufacturer, consumers often face problems. The embarrassment and trouble of needing to buy a pen again caused a waste of resources, so it is necessary for us to design a self-adjustable gel pen shell for different lengths of pen refills on the market, which is convenient for consumers to use
