A jet port is opened on the side of the jet box 18, and the jet port is set toward the monitoring and measuring instrument 4. When the movable plate 11 moves downward in the installation box 10, the gas in the installation box 10 enters the jet box 18 through the jet pipe 16, and the airflow entering the jet box 18 is ejected through the jet port, which is used to clean foreign objects at the measuring end of the monitoring and measuring instrument 4.
