[0006] As a further solution of the present invention: a plurality of card slots are opened in a circular array on one side of the air inlet away from the air compressor inlet pipe, and card blocks are inserted through the plurality of card slots, and the plurality of card blocks are fixedly connected to the outer wall of the same air inlet cavity.

[0007] As a further solution of the present invention: the silencer pipe and the air inlet cavity are located on both sides of the bidirectional screw, and the silencer pipe is located at the air outlet position of the mounting pipe.

[0008] As a further solution of the present invention: a first through hole and a second through hole are respectively formed on both sides of the air inlet cavity, and the aperture of the second through hole is larger than the aperture of the first through hole.

[0009] As a further solution of the present invention: a plurality of conical protrusions are fixedly connected in an arc shape on one side opposite to the two splints, and a rotating handle is fixedly connected to the top and bottom ends of the bidirectional screw.

[0010] As a further solution of the present invention: two abutment blocks are symmetrically and fixedly connected to the outer wall of the lifting tube, and the two abutment blocks are tightly fitted on both sides of the mounting plate.

[0011] As a further solution of the present invention: the silencer pipe is clamped in the mounting pipe, the silencer pipe is located on one side of the air compressor intake pipe, the intake cavity is made of glass fiber cotton, and the silencer pipe is made of metal sintered felt.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] When the two splints are brought close to each other, they can be clamped on the outer wall of the air compressor intake pipe for installation, and a number of conical protrusions are provided on the splints for tightly sticking to the outer wall of the air compressor intake pipe, which can increase friction and effectively increase the firmness of the installation. When the air compressor intake pipe takes in air, the gas will enter the intake cavity through the air inlet port, and then the intake cavity is made of glass fiber cotton and can form a special cavity for sound absorption, thereby effectively reducing the aerodynamic noise generated during air intake, and finally enters the air compressor intake pipe through the metal sintered felt silencer pipe for sound absorption again, which can effectively control the noise directly from the propagation path.

[0014] The utility model is easy to use, and both the air intake cavity and the silencer pipe can absorb sound, which can effectively control noise from the source to reduce noise. Rotating the handle can drive the two clamps to approach each other and clamp them on the air compressor intake pipe for quick installation. The installation pipe adopts a small volume design as a whole, which is more convenient to use and install. BRIEF DESCRIPTION OF THE DRAWINGS
