In such circumstances, a single path of gas only enters, thus preventing the fuel oil and gas from mixing and burning, and ensuring the stable operation of the entire machine. When the knob 21 is turned to the right on the gearwheel for the gas, the button 21 drives the cam 24 in rotation to the right so that the first microvalve 22 and the second microvalve 23 are not depressed, while the valve interior 12 is rotated to the right so that the oil conduit 1211 in the valve interior 12 connects the oil intake line seal 111 to the oil delivery line joint 112, and in such circumstances, the steel ball is located in the positioning hole 131 corresponding to the valve plug 13. The first microvalve 22 is set to be normally passing, and then the ignition coil 3 can make the ignition when electrified. The second microvalve 23 is set to be normally locked, then the carburetor solenoid valve 4 is de-energized and the main carburettor measurement hole opens; and the oil intake line seal 111 communicates with the oil delivery line seal 112 so that the fuel oil enters the carburetor cup.
    When the gearwheel is switched from the gearwheel for the fuel oil to the gearwheel for the gas, or when the gearwheel is switched from the gearwheel for the gas to the gearwheel for the fuel oil, the time of switching is very short, and the ignition coil 3 is de-energized for a moment and then electrified again, so that the motor does not stop and can continue to operate due to the inertia effect. No experience is required to perform the switching, and switching is stable and random.
