A first fixing plate 6011 is fixedly connected to the left side of the silencing cover 2. A plurality of sliding grooves 6013 are formed in the left side of the fixed disk 6012. A slider 6014 is slidably connected to the inner side of each of the plurality of sliding grooves 6013. A mounting branch plate 60110 is fixedly connected to the left side of the slider 6014. A first rotating block 6015 is fixedly connected to the left side of the mounting branch plate 60110. A first inclined plate 6016 is rotatably connected to the outer side of each of the plurality of first rotating blocks 6015. A second rotating block 6017 is rotatably connected to the outer side of the left end of the first inclined plate 6016. A moving ring 6018 is fixedly connected to the left side of the second rotating block 6017. A rotating ring 6019 is rotatably connected to the left side of the moving ring 6018. A through hole adapted to the mounting branch plate 60110 is formed in the outer side of each of the plurality of first fixing plates 6011. An internal thread is provided on the inner side of the rotating ring 6019. An external thread is formed on the outer side of the air inlet pipe 5. The internal thread and the external thread are adapted to each other. The mounting branch plate 60110 is slidably connected to the first fixing plate 6011. When installing the air inlet pipe 5, first place the air inlet pipe 5 on the left side of the silencing cover 2, and then rotate the rotating ring 6019. The rotating ring 6019 drives the moving ring 6018 to move. The moving ring 6018 drives a plurality of mounting branch plates 60110 to move. The mounting branch plates 60110 approach the first fixing plate 6011 and pass through the through hole, so that the mounting branch plates 60110 pass through the first fixing plate 6011, which facilitates the preliminary installation of the air inlet pipe 5.

The rotating ring 6019 drives the moving ring 6018 to move. The moving ring 6018 drives the plurality of mounting branch plates 60110 to move. The mounting branch plate 60110 approaches the first fixing plate 6011 and passes through the through hole, so that the mounting branch plate 60110 passes through the first fixing plate 6011, facilitating the preliminary installation of the air inlet pipe 5.
[0022] The sealing assembly 602 includes a second fixing plate 6022 which is fixedly connected to the outer side of the muffler cover 2. A fixing frame 6021 is fixedly connected to the outer side of the second fixing plate 6022. An air tank 6023 is fixedly connected to the inner side of the fixing frame 6021.

When installing the air inlet pipe 5, the installation branch plate 60110 presses against the lifting plate 6026 to move. The lifting plate 6026 drives the moving rod 6025 to move. The moving rod 6025 drives the piston plate 6024 to move, so that the piston plate 6024 pushes out the gas in the airbag 60211. The gas enters the annular pipe 6029 through the connecting pipe 6028 and enters the airbag 60211 through the delivery pipe 60210, causing the airbag 60211 to expand. This facilitates the sealing operation of the connection of the air inlet pipe 5 by the airbag 60211, reduces the vibration at the connection of the air inlet pipe 5, and prevents noise generated by air leakage at the connection.
[0023] The stabilizing component 603 includes a guide plate 6032 which is fixedly connected to one side of the first fixing plate 6011 close to the air inlet pipe 5. A guide block 6033 is slidably connected to the outer side of the guide plate 6032. A bottom plate 6034 is fixedly connected to the outer side of the guide block 6033. A rectangular hole 6031 is formed in the outer side of the first fixing plate 6011. A clamping plate 6035 is arranged on the outer side of the bottom plate 6034.

The clamping plate 6035 is slidably connected to the bottom plate 6034. A connecting block 60313 is fixedly connected to the outer side of the abutting plate 6027.

The bottom plate 6034 drives the clamping plate 6035 to move, making the clamping plate 6035 approach the L-shaped block 6036. At the same time, the clamping plate 6035 drives the sliding rod 60314 to move. Due to the limitation of the inclined slot 60316, the clamping plate 6035 moves in the direction away from the first fixing plate 6011, making the clamping plate 6035 fit with the L-shaped block 6036, facilitating the re-limitation of the air inlet pipe 5, increasing the stability of the installation of the air inlet pipe 5, and preventing the air inlet pipe 5 from loosening.
[0024] Working principle: When in use, the staff first place the air inlet pipe 5 on the left side of the sound insulation cover 2, and then rotate the rotating ring 6019. The rotating ring 6019 drives the moving ring 6018 to move. Under the action of the first inclined plate 6016 and the slider 6014, multiple installation branch plates 60110 move closer to the first fixing plate 6011, facilitating the preliminary installation of the air inlet pipe 5 by the installation branch plates 60110. At the same time, the installation branch plates 60110 drive the lifting plate 6026 to move. Under the action of the moving rod 6025, the piston plate 6024, the connecting pipe 6028, the annular pipe 6029 and the conveying pipe 60210, the airbag 60211 expands, facilitating the sealing operation of the air inlet pipe 5 by the airbag 60211, avoiding noise generated by air leakage at the connection of the air inlet pipe 5. At the same time, the abutting plate 6027 drives the toothed plate 60312 to move. Under the action of the gear 6038, the rotating shaft 6037, the turntable 6039, the control block 60310, the second inclined plate 60311, the guide block 6033 and the bottom plate 6034, the clamping plate 6035 moves towards the L-shaped block 6036. At the same time, through the sliding rod 60314 and the inclined groove 60316, it is convenient for the clamping plate 6035 to move away from the first fixing plate 6011, facilitating the clamping plate 6035 to reinforce the air inlet pipe 5 again and increasing the stability of the air inlet pipe 5.
