Pilot here who does pilot things on occasion.
The propeller blades are linked to a piston inside the propeller hub that moves forward and aft under oil pressure in response to the pilot’s controls. As the piston moves, it pushes against and rotates the propeller blades in their sockets and alters their pitch. This whole assembly rotates as the propeller spins.
