The support portion 212 is arranged in a Y-shaped structure, which not only ensures sufficient strength to support the circular ring portion 211, but also avoids the need of supporting more weight of the rotating arm 3 caused by the adoption of a member with the same width as the circular ring portion 211 to connect the circular ring portion 211 and the rotating arm 3.
It should be noted that the guide rail provided on the top surface of the circular ring portion 211 is a rail arranged to protrude from the top surface or a second groove provided on the top surface of the circular ring portion 211. When the guide rail is a rail protruding from the circular ring portion 211, the first roller of the rotating rail 22 is provided with a third groove, and the third groove is matched with the rail, that is, the first roller rolls along the guide rail through the matching of the third groove and the rail; when the guide rail is a second groove, the first roller wheel part is arranged in the second groove and rolls along the second groove.
