A pawl is a tiny hinged arm, with its free end resting against a serrated surface. It can slide over the surface in one direction, but will catch on the serrations when going in the other direction. It's what makes it possible for a bike to coast.

The pawl drops into the gap between the teeth of the ratchet as the clock key turns the spring barrel. The pawl clicks over the teeth until the key turning pressure is removed. The pawl then drops into the last notch in the toothed wheel and stops the spring unwinding.
