Description

technical field [0001] The invention relates to a pen, in particular to a retractable pen. Background technique [0002] Existing retractable pens, such as Patent No.: 200610051919.9 Domestic Invention Authorization Patent provides a retractable pen with a refill, which supplements the vacancy that the traditional retractable pen lacks the effect of swinging, so that it has more diversified utility; however, Its disadvantage is that people pay more attention to the operation method in actual use, which is closer to people and makes people feel more convenient. Therefore, what we should judge is that pressing and shaking are more suitable for people, and determine its advantages and disadvantages. After making a choice, further optimize its structure to make it more usable and ergonomic; [0003] If possible, the operation method should be further simplified to improve stability; the traditional pressing operation method has been used for a long time, and a more novel and sc...
