Several slots 8 are opened at equal angles on the monitoring cover 7 so as to block the top opening of the monitoring cylinder 3. Several limiting blocks 22 are fixed at equal angles on the inner wall of the monitoring cylinder 3, and the limiting blocks 22 are movably locked on the bottom surface of the monitoring cover 7 to limit the position of the monitoring cover 7.

[0033] The card plate 9, there are several card plates 9, and the several card plates 9 are respectively screwed into the groove 6 by rotating rods, and one end of the card plate 9 is movably locked in the slot 8. The card plate 9 is used to restrict the monitoring cover 7, so as to fix the monitoring cover 7 on the monitoring cylinder 3.

[0034] The abutment rod 10, there are several abutment rods 10, which are movably inserted into the inner wall of the groove 6 at equal angles. The bottom end of the abutment rod 10 is fixedly connected to the air pressure ring 23, and the top end of the abutment rod 10 is set to abut against the other end of the clamping plate 9. The abutment rod 10 is used to restrict the rotation of the clamping plate 9, thereby fixing the monitoring cover 7 on the monitoring cylinder 3.

[0035] The air nozzle 11 is installed on the monitoring cylinder 3 and is connected to the air pressure groove 5. The air nozzle 11 is used to control the air pressure in the air pressure groove 5.
