Description

Technical Field

[0001] This utility model belongs to the field of ballpoint pen technology, and specifically relates to a ballpoint pen and its flexible adjustment structure. Background Technology

[0002] A gel pen is a commonly used writing instrument. Its core characteristic is the use of gel-like ink (also known as "neutral ink"). It combines some advantages of fountain pens and ballpoint pens, offering a balanced performance in writing smoothness, handwriting stability, and applicability. Therefore, it is widely used in daily writing, office note-taking, and student assignments. Gel pens come in many specifications on the market, and different users choose different ones to meet their specific needs. For example, some gel pens have different weights because different users have different weight requirements. However, existing gel pens cannot adjust the weight at the end to suit different needs or scenarios. For instance, in fast writing, it may be necessary to balance the overall weight, or in other writing needs, the weight at the end may need to be increased to meet daily writing requirements. This limits the usability of existing gel pens and prevents flexible adjustment.

[0003] In summary, we hope to propose a new structure to solve the aforementioned technical problems. Utility Model Content
