So set up, in the pivot rotation process, the round pin axle keeps quiescent condition for the fixed axle. The rotator rotates around the pin shaft, so the problem that the central shaft of the rotating shaft is loosened can not occur.

Preferably, the surface of the fixed shaft is provided with a limit groove; the rotating body is provided with a limiting convex rib; when the rotating body is connected with the fixed shaft, the limiting convex rib is positioned in the limiting groove.

The fixed shaft is provided with a limit groove, and the rotating body is provided with a limit convex rib. The limiting convex rib is embedded into the limiting groove. So set up, the rotator can only rotate at the angular range of spacing groove. The size of the limiting groove can be selected according to requirements, so that the rotating angle of the rotating body can be adjusted.

Preferably, the rotating body is provided with a first fixed block in a connecting manner; the fixed shaft is connected with a second fixed block.
