There’s a plate spinning with the propeller that gets pushed forward and back, and there’s a linkage to each blade that rotates it when this happens. It might help to search “variable pitch propeller mechanism”. A more complicated version of the same mechanism, called a swash plate, is used to control the main rotor on a helicopter.
