How does a locking pulley work?

The locking pulley is a simple pulley, except with two wheels instead of one. When the cord is pulled outward, it moves one of the wheels, causing the entire mechanism to lock. This enables the user to keep the blinds, or whatever object is attached to the pulley, in place without holding the cord.

How does a rope pulley hoist work?
