If the firmness is insufficient, it will have an adverse effect on the posture and stability of the vehicle body. If the installation is complicated, the production cost will be increased. The existing air suspension air intake connector often adopts a single connection method, which makes it difficult to balance the firmness and convenience of the air intake connector installation at the same time. By respectively arranging a snap and an anti-rotation member at the end of the air intake connector, an air intake hole is provided on the shell, and the snap can snap the air intake connector to the air intake hole so that the air intake connector is connected to the inside of the shell. The inner wall of the air intake hole of the shell is also provided with an axial anti-rotation groove, and the anti-rotation member can be embedded in the anti-rotation groove to prevent the shell and the air intake connector from rotating and avoid leakage.
