The knob requires application of less force to turn the knob than what's needed to turn the shaft by itself.

When the knob on one side of the door is turned, the shaft retracts the spring-loaded latch that holds the door closed. Without the knob in place, more force would be needed to turn the shaft and retract the latch. How Doorknobs Work as a Simple Machine.
