The Trigger Of QIN Crossbow

in #busy5 years ago (edited)

Well,After a period of effort,We finally figured out the mechanism of the qin crossbow trigger。

It was a breakthrough invention in that dynasty。I mean,It still seems a pretty ingenious creation today。I really believe that most people today still don't know the key to it, or even how it works。

But it doesn't matter,We will show you how it works,This is the analysis of the angle motion after the pull of the trigger。

Before pulling the trigger。If no force is applied to the trigger, the system locks itself。This is the key, small changes may not be self-locking。Basically all the online diagrams are wrong, they can't implement self-locking, they have fatal defects。

Unlocking condition,It takes almost 10 degrees to unlock the trigger。

After launch。

And if you want,you can make one according to the sketch,it should be works。
