Because the torque is less. The door knob has less to move, through a smaller resistance, than an axle, which usually turns a wheel to move (for example) a car.
A door knob is a type of simple machine known as a wheel and axle. It consists of a wheel (the knob) that rotates on an axle to open or close a door.
The knob is the 'wheel' and the rod that goes through lock is the 'axle'
Door knobs are considered a type of wheel and axle simple machine. Turning the knob creates rotational motion around an axle, enabling the door to open or close.
The door knob is the wheel, and the axle is inside of it allowing it to spin and open, the wheel uses a small force and the axle strengthens it up.
It is easier to push open a door using the knob because the knob is located further away from the hinge, which means the force from pushing is applied farther from the rotation point (hinge), resulting in less resistance. Additionally, the design of the knob allows for a better grip, making it easier to apply force effectively.
Turning a knob provides a larger surface area for your hand to grip onto, allowing for more leverage and better control over the movement compared to turning the smaller axle directly. This makes it easier to apply the necessary force to rotate the knob. Additionally, knobs are designed to be more comfortable for human hands to use, reducing fatigue during repeated use.

round operating mechanism
yes it is because it turns like a wheel and every wheel has a axle
The knob acts as the wheel as it spins on something inside which acts as the axle
