Nuts 26 are rotationally connected to the outer sides of the fixing rings 25, the nuts 26 are located on the outer sides of the corresponding through holes 29, and the nuts 26 are screwed on the outer sides of the corresponding screw rods 22.
[0026] In this embodiment, the device can absorb and buffer these vibrations and reduce the transmission of vibrations to the vehicle body and other components when in use through the flexible structure and corrugated design of the telescopic tube 1; at the same time, the internal sound attenuation structure can make the high-speed flowing exhaust gas pass through multiple channels and rub against each other to reduce the airflow speed, thereby effectively reducing the noise; when the telescopic tube 1 needs to be replaced due to damage or aging during use, the nuts 26 are unscrewed from the threaded rods 22 by rotating the nuts 26, and the multiple nuts 26 are rotated by a certain distance in sequence when the nuts 26 are rotated, until the multiple nuts 26 are unscrewed from the corresponding threaded rods 22, and the fixing ring 25 is removed from the outside of the threaded rods 22 at the same time.
