The present invention discloses a safety device regulator comprising a pressure adjusting plate, a safety pin rod, a safety pin, an initiation disk, a safety disk, an admission piece, an air outlet, a valve stem, a safety pin rod spring, a safety disk tension spring, a regulator body and a transmission shaft; said pressure adjusting plate is connected with said valve stem; said valve stem is connected with said regulator body; said safety pin rod is connected with said regulator body; said safety pin rod spring is connected with said safety pin rod; said initiation disk is connected with said regulator body; said safety disk is in contact with a concave on said safety pin rod; said safety disk tension spring is connected with said safety disk. As to the safety device regulator of the present invention, when the pressure of a gas container exceeds the preset safety pressure of a valve body, the overpressure cutout device and flow path cutout device are triggered to separate the gas container from the valve body or cut off gas influx; in addition, it can further comprises an electromagnetic valve. When fire from a burner is extinguished due to wind or other factors, the electromagnetic valve becomes active to cut off gas from the valve body to further ensuring the safety.
