The top of the exhaust gas treatment box 4 is provided with an air inlet hole in communication with the inner cavity thereof. Before the one side of the sealing plate 3 is connected to the one side of the mounting plate 2, the free end of the air outlet hose is inserted into the inner cavity of the air inlet hole until the free end of the air outlet hose penetrates through the air inlet hole and extends into the inner cavity of the exhaust gas treatment box 4. Then, the one side of the mounting plate 2 is attached to the one side of the sealing plate 3, and then the mounting plate 2 and the sealing plate 3 are fixed by using bolts and nuts. Thus, the air in the accommodation groove can be transmitted into the inner cavity of the exhaust gas treatment box 4.

[0041] The bottom of the fixing column 9 is fixedly provided with a T-shaped limiting column 10, and the bottom of the mounting plate 2 and the sealing plate 3 is provided with a mounting groove matched with the T-shaped limiting column 10.
