The cone pin, or shear pin, is used to attach the propeller to the drive shaft so that if you hit something hard with the propeller, you only break the shear pin, and not the expensive drive shaft, motor, or propeller.
Or, more specifically, that you only break the shear pin and propeller, not the drive shaft or motor.
