Description

technical field [0001] The invention relates to a pen, in particular to an automatic mechanical pen. Background technique [0002] In today's market, there are all well-organized pens without any detachable value; now it has entered the 21st century, and in this new century, the status quo is still the same, although people's technological development is increasing day by day; however, the pen as the basis The importance of writing tools is still indispensable; and with the quickening pace of life, people have also used the above-mentioned structural pens for decades, and the desire for new pens is still very urgent. [0003] Secondly, the above-mentioned several pens still have great structural defects, and the newly launched lifting pen, patent number: 2019106855133; just makes up for the convenience of the above-mentioned pens. At the same time, it also gives people more and better choices, and provides people with better and faster operation methods. [0004] On the ba...

Problems solved by technology

[0004] On the basis of the above-mentioned lifting pen, the space for DIY and assembly is small, and the extension distance of the pen core is fixed. Of course, the fixing of the extension distance of the pen core does not affect people's normal use; however, it can Freely control the retractable distance of the refill, which is a great breakthrough for some pen lovers;

[0005] Moreover, the above-mentioned pens have a relatively single core-retracting method, often only one; moreover, they cannot be structurally locked and are not easy to carry

[0006] Moreover, any pen currently on the market is not equipped with the function of automatically retracting the refill, and the lack of this function will make it easy to damage the refill when the user forgets to retract the refill and the pen accidentally drops after use. It is also easy to contaminate the carrier's clothing, bag or surrounding environment
