The damper 23 keeps the vibration-damping spring 22 stable and will not be deformed by the vibration, thereby reducing the vibration of the generator 1 and the noise generated. The vibration generated by the generator 1 at different starting powers is different. By rotating the rotating shaft 35 to move the rotating shaft 35 on the threaded ring 24, the compression degree of the vibration-damping spring 22 is adjusted, and the stress of the vibration-damping spring 22 is changed, so that the reaction force will not be transmitted to the generator 1, thereby quickly and effectively adapting the vibration-damping spring 22 to different working conditions of the generator 1, thereby improving the vibration reduction and noise reduction effect.
