Retractable pen (click pen): How it works

This animated three-dimensional model of a retractable pen
visually explains the working principle of this mechanism.
A truly nice piece of engineering of our everyday life.
The 3D model can be accessed on Sketchfab [ skfb.ly/Tq9N ].

besides of when it clicks, it doesn't explain anything.

Could you, please, make a video on how the twist mechanism of mechanical pencils works?
I have seen some videos that explain the clutch mechanism,
but I haven't seen any video that explains the screw based mechanical pencils.
Thanks

incredible video Christophe, thanks for sharing

I have been looking for someone who can fix my cheaper pens. Can you fix them? For how much?
These days, people usually fix only the expensive things. But I’m interested in sustainability for all things.
