In this way, when the air pipe shakes or vibrates, the air pipe can be lifted up, which can reduce the shaking amplitude of the connection between the air pipe and the air inlet pipe 3 and the air outlet pipe 4, thereby avoiding loose connection and affecting air tightness, reducing the probability of air leakage. The number of horizontal plates 6, connecting rods 7 and supporting rings 8 are all two groups. The surface of the vertical rod 5 is provided with a nut 9, and the surface of the vertical rod 5 is provided with a thread, and the thread is meshed with the nut 9. Loosen the nut 9, then the limit of the horizontal plate 6 can be released, and then the horizontal plate 6 can be rotated counterclockwise, so that the supporting ring 8 can be folded on the surface of the Roots blower body 2, and then the nut 9 is tightened. When tightening the nut 9, the nut 9 can squeeze the horizontal plate 6, and the friction force of squeezing can fix the horizontal plate 6.

When tightening the nut 9, the nut 9 can squeeze the cross plate 6, and the friction force of squeezing can fix the cross plate 6, and the friction force can be increased by the rubber pad 10, so that the cross plate 6 can be fixed. The plate 6 is fixed more firmly, so that the supporting ring 8 can be prevented from shaking. The shielding cover 14 can cover the surface of the Roots blower body 2, and then the sound-absorbing layer 15 can absorb the noise generated when the Roots blower body 2 is working, thereby reducing part of the noise. If there is no need for noise reduction, the staff only needs to pull the shielding cover 14 outward through the handle 17, and the shielding cover 14 then drives the plug 13 to slide in the slot 12 until the shielding cover 14 is pulled out. At this time, the shielding cover 14 can be removed, and when installing the shielding cover 14, it is only necessary to align the plug 13 under the shielding cover 14 with the slot 12 and insert it. After the plug 13 is inserted, it can resist the magnet 16. At this time, the magnet 16 can absorb the plug 13 made of ferritic stainless steel due to the action of magnetic force, so that the shielding cover 14 can be limited.
