As described in other posts, the blades are moved using oil pressure via a piston in the propeller hub that connects to the blades.

The way that the force to move the spinning propeller gets to the propeller is through oil passageways in the propeller shaft. Much the same way that lubrication oil is passed from the crankcase through main bearings to the crankshaft, then through passageways in the crankshaft to the connecting rods and through passageways in the connecting rods tot he piston’s wrist pins.
