This is a 3D printed sectional demonstration model of the ancient Qin Dynasty bronze crossbow trigger.

It is only for structural display and has no actual firing function. The sectional design allows you to directly view its exquisite internal core structure.

The original Qin crossbow trigger was made of bronze. It adopts an ingenious minimalist structure with very few parts. It requires no springs at all and relies purely on the elastic force of the crossbow itself to complete firing.

Core components include the sight, the trigger and the string hook. It fully reflects the extraordinary mechanical wisdom of ancient craftsmen.
