Lower mounting sleeve groups 4 are fixedly installed on the stabilizing frames. The upper mounting sleeve groups 3 and the lower mounting sleeve groups 4 include two mounting sleeve units, and the two mounting sleeve units are arranged in a "V" shape. Through the "V" shape setting, it is convenient for the upper mounting sleeve groups 3 and the lower mounting sleeve groups 4 to be connected by the connecting rod 2 and enclose a triangular shape to further improve its stability.

A return spring 19 is arranged between one end of the shock absorber block 20 and the inner bottom surface of the sleeve body 18.

[0038] Working principle: When the stabilizing mechanism is in use, first prepare three stabilizing frames, and then tightly hold the smoke pipe at intervals in sequence with the three stabilizing frames. After the stabilizing frames are tightly held, they are locked with locking bolts 13, thus completing the installation of the stabilizing frames on the smoke pipe. Immediately afterwards, install the upper sound insulation board 6, the left sound insulation board 7, the right sound insulation board 8 and the lower sound insulation board 9 between the respective stabilizing frames, so that the upper sound insulation board 6, the left sound insulation board 7, the right sound insulation board 8 and the lower sound insulation board 9 form an enclosed state around the smoke pipe. Then, fix the upper sound insulation board 6, the left sound insulation board 7, the right sound insulation board 8 and the lower sound insulation board 9 with a screw rod 17, thereby fixing the installation of the upper sound insulation board 6, the left sound insulation board 7, the right sound insulation board 8 and the lower sound insulation board 9 between the stabilizing frames.
