In practical applications, the connection manner of the mounting member 530 and the face ring 520 is various, such as connection by bolts, and the specific structure of the mounting member 530 can be set according to practical needs, such as using a snap, a threaded connector, or other clamps, and the specific arrangement form of the mounting member 530 is not limited herein, and can be understood by those skilled in the art.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
