[0018] The electric push rod, return spring, top-loading rod, and loading plate facilitate the lifting and lowering of the loading plate, which pushes the gunpowder in the gunpowder metering cylinder into the signal flare's cylinder. The fixed baffle, which is hinged to the bottom of the gunpowder metering cylinder by a spring hinge, opens to seal the bottom of the gunpowder metering cylinder when subjected to a large downward pressure, allowing the gunpowder to fall into the signal flare's cylinder. When the pressure is released, the fixed baffle returns to its original position under the action of the spring hinge. Attached Figure Description
