The present invention drives the first knocking ball and the second knocking ball to repeatedly contact the surface of the tube body part through the entire sliding plate moving back and forth inside a group of rectangular frames close to the surface of the tube body part, thereby knocking the tube body part plugged and fixed inside the rectangular shell, avoiding the smoke entering the tube body part and adhering to the inner surface of the tube body part during the later monitoring process, preventing it from affecting the later smoke monitoring process, and improving the effect of the later smoke monitoring.

[0034] 2.

9. The monitoring method of a flue gas monitoring device according to claim 8, characterized in that: The following monitoring methods are included: T1. Through the plug-in fit between the L-shaped plug-in board and the plug-in frame, the entire pipe body is plug-in fit inside the plug-in interfaces respectively opened at the ends of the connecting pipe and the smoke inlet pipe inside the rectangular shell, thereby completing the plug-in and fixed installation of the pipe body; After steps T2 and T1 are completed, the top of the rectangular shell is sealed by rotating and fixing the external bolts with the threads of the first ear plate and the second ear plate 340. After the sealing is completed, the entire device is connected and fixed to the inlet end of the flue gas duct through the connecting flange, so as to perform suction analysis operations on the discharged flue gas later; After steps T3, T1 to T2 are completed, the drive motor and the smoke monitor are started synchronously to drive the smoke fan blade fixed to the output shaft of the drive motor to rotate, so that the smoke in the external environment passes through the fan-shaped cover, the oblique pipe, the guide pipe, and the smoke inlet pipe in sequence into the pipe body, so that the incoming smoke is monitored for substances through the smoke monitor; T4. During the material monitoring process, the output shaft of the driving motor is rotated to drive the scraper assembly installed inside the plug-in slot to rotate synchronously, so as to scrape off the smoke material attached to the inner wall of the conical cover, and the suction fan in the rotation process is used to perform the suction operation; T5. The synchronous rotation of the scraping assembly causes the sliding ball to repeatedly slide circumferentially on the bottom of the plug-in tube and the plurality of second grooves provided on the bottom of the plug-in tube, and in combination with the second spring fixedly connected between the slider and the rectangular groove, repeatedly compresses and stretches, driving the movable side plate to synchronously move left and right in the horizontal direction inside the rectangular shell; T6. When the movable side plate synchronously moves horizontally left and right inside the rectangular shell, the movable side plate and the first grooves on the side of the movable side plate are sequentially and repeatedly slidably matched with the abutment balls respectively fixed on one side of the two lower extension plates, and this is combined with the elastic force of the first spring fixedly connected between the rectangular frame and the sliding plate, so that the two abutment balls repeatedly move forward and backward to a certain extent; T7.
