The mounting block is arranged on the connecting flange 2 and connected thereto, and the mounting block and the connecting block are symmetrically arranged with respect to the central axis of the connecting flange 2. The lower end of the arc-shaped rack is arranged on the mounting block and connected thereto. The connecting flange 1 is provided with a matching plate connected thereto, and a movable groove is provided on the matching plate for the upper end of the arc-shaped rack to pass through and be installed. The movable tooth is arranged in the movable groove and meshed with the arc-shaped rack.

[0007] In the above-mentioned bellows assembly, the matching plate is located in the movable groove and is provided with a motor connected thereto and having an output shaft, and the movable teeth are provided on the output shaft and connected thereto.

[0008] Compared with the prior art, the bellows assembly has the following advantages:

[0009] 1. Both ends of the corrugated body are respectively provided with a connecting flange 1 and a connecting flange 2 which are connected thereto and are convenient for connecting other pipe fittings. An adjusting unit 1 which is connected thereto and is used for axial adjustment is provided between the connecting flange 1 and the connecting flange 2. An adjusting unit 2 which is connected thereto and can be bent and adjusted is also provided between the connecting flange 1 and the connecting flange 2.
