The outer sides of the intake pipe 2 and the left connecting pipe 11 are adapted to each other, and several spliced ​​air ducts 3 are prepared as needed. The right connecting pipe 4 is respectively connected with the intake pipe 2 and the left connecting pipe 11 of the adjacent spliced ​​air duct 3, so that the convex ring and the sealing groove 41 are engaged and connected. At this time, the two-way screw 6 is driven to rotate by turning the knob 8, so that the front and rear engaging blocks 10 are close to each other, and the left connecting pipe 11 of the intake pipe 2 and the adjacent spliced ​​air duct 3 is engaged and fixed, so that the convex ring and the sealing groove 41 are sealed through the sealing ring, so as to realize the sealed connection of multiple spliced ​​air ducts 3 and the intake pipe 2, thereby facilitating the increase and decrease of the filtering structure and improving the versatility of the exhaust gas purification device.
