[0041] As a preferred embodiment, a connecting block 503 is fixedly installed on one side surface of the connecting piece 501, and the connecting block 503 is arranged in a T shape. A connecting groove 504 matching the connecting block 503 is opened on the other side surface of the connecting piece 501, and the connecting block 503 and the connecting groove 504 are snap-fitted together.
