Rotating mechanism

The utility model relates to a rotating mechanism which comprises a rotating structure, threaded connecting pieces which are annularly distributed at equal intervals are arranged on the outer side of the rotating structure, fixing supports perpendicular to the rotating structure are installed on the inner sides of the threaded connecting pieces, butt joint grooves are formed in the outer sides of the fixing supports, and hanging structures are installed on the outer sides of the fixing supports at equal intervals. By means of the butt joint groove, the matched hanging disc, the threaded hole, the bolt and the rubber head, the bolt can rotate in the threaded hole in a threaded mode to move towards or away from the butt joint groove, and when the bolt is away from the butt joint groove, the bolt can rotate in the threaded hole to move towards or away from the butt joint groove. The hanging plates can slide freely to adjust the distance between the outer sides of the movable rods, when the bolts are perpendicula
