I've never really gotten exactly how the trigger/nut thing works, could you explain?

  How about a simple lever ... with a notch???

Bikewer:
Ever look at the innards of a revolver?   When the hammer is at full cock, the trigger engages a small notch on the hammer assembly.  That's what keeps it from flying forward.  When you pull the trigger, it comes out of engagement with the notch, and the hammer falls.

Same principal (actually, I imagine firearms borrowed the principal from crossbows!) here.   The nut, at full cock, holds the bowstring around the two little uprights, and the bolt or arrow lies between them, in contact with the string.  When you pull the trigger, the whole assembly is free to pivot forward, and off she goes.
Here's a slightly better illustration:

Aha! it all makes sense now!  :)  Thanks for the explaination, now I might want to build one.
