Which mechanism caused repeating crossbows in ancient China to achieve high firing rates, despite limited trigger sensitivity?

💡 Explanation

When trigger is activated, the repeating crossbow uses a cam-driven bolt loading sequence because the rotating cam translates continuous motion into cyclical loading and firing, enabling rapid bolt deployment. Therefore cam-driven loading resulted, rather than oscillation damping, pin reloading, or gravity actuation, which are less mechanically efficient.
