A plurality of hanging assembly holes 1001 are provided at the bottom of the assembly panel 10, and the assembly hanging screw barrel 9 is adapted to the hanging assembly hole 1001. Specifically, when assembling the installation and fixing structure of the exhaust gas adsorption device, the assembly panel 10 is first screwed to the rear of the automobile frame, and then the position of the exhaust gas adsorber body 1 is roughly determined according to the shape and position of the automobile exhaust pipe, and then the two screws are screwed together. The tubes 2 are respectively screwed on the intake end and the exhaust end of the exhaust adsorber body 1, and then the folded bellows 3 on both sides are bent and the length of the telescopic tube 4 is respectively adjusted so that the position of the inner row pipe 6 corresponds to the position of the exhaust pipe. Then, a plurality of fastening bolts are selected, and the bottom ends thereof pass through the hanging assembly hole 1001 from the top of the assembly panel 10 and are respectively screwed on the inside of each assembly hanging screw barrel 9, and the two screw tubes 2, the outer row pipe 5 and the inner row pipe 6 are hung and positioned, thereby fixing the exhaust adsorber body 1 and keeping the overall shape of the pipeline installation structure fixed.

At the same time, when the operation of the car causes one end of the exhaust pipe to tend to lift upward, the assembly panel 10 and the positioning suspension screw barrel 16 will play a restraining role. When the exhaust pipe has a tendency to swing downward, the positioning suspension screw barrel 16 will drive the upper clamping handle 12 to have a tendency to move upward relative to the exhaust pipe, so that the spring clip 11 can clamp the elastic cloth tube 7 more tightly to prevent the elastic cloth tube 7 from slipping.
