AI Technical Summary
Traditional push-button pens have a short refill length due to the push-button telescopic mechanism being located at the top of the refill, which affects the ink capacity.
The design employs a rotating ring and a pressing cap, placing the pressing and telescopic mechanism outside the pen refill. The refill's extension and retraction are achieved through the combination of the rotating ring and the pressing and telescopic mechanism inside the pressing cap, eliminating the need for a pressing and telescopic mechanism at the top of the pen refill.
The length of the pen refill was increased to be roughly the same as the overall length of the pen, thereby increasing the ink capacity.
