The connecting unit includes a quick-release part and a fixing part. The quick-release part includes a quick-release piece and a clamping part clamped with the end of the quick-release piece. The clamping part is fixed to the air filter housing 1. The quick-release piece includes an integrally formed ball end 3 and a connecting rod 4. A ball groove 5 that cooperates with the ball end 3 is opened in the clamping part. The ball groove 5 in the clamping part can be tightly matched with the ball end 3, so that the air filter housing 1 can be firmly fixed on the clamping part during installation, avoiding loosening or falling off due to vibration or other external forces, and providing additional stability when the vehicle is driving; the cooperation between the ball end 3 and the ball groove 5 provides a flexible range of motion, so that precise alignment is not required during installation, and the ball end 3 is pressed into the ball after alignment. The groove 5 can be used, and the installation operation is more convenient. In this embodiment, a stepped annular groove 6 is provided at the bottom of the connecting rod 4, and a mounting hole 7 that can abut the stepped annular groove 6 is provided on the connecting plate 2.
