1. A rotating device, comprising:
a first member comprising an anti-rotation groove and at least one first connecting portion; and
a second member comprising an anti-rotation protrusion and at least one second connecting portion,
wherein the anti-rotation groove comprises a first inner surface and a second inner surface forming a first sharp corner, the anti-rotation protrusion comprises a first outer surface, a second outer surface and a third outer surface, the first outer surface and the second outer surface forms a second sharp corner, and the third outer surface is located at a periphery of the second sharp corner,
an angle of the first sharp corner is equal to that of the second sharp corner, and the second inner surface and the third outer surface are intersected at a central axis of the rotational connection, and
the at least one first connecting portion and the at least one second connecting portion are rotationally connected, and the anti-rotation protrusion enters the anti-rotation groove, such that the second outer surface of the anti-rotation protrusion is in contact with the third outer surface of the anti-rotation groove to prevent the at least one first connecting portion from rotating in a second direction opposite to the first direction with respect to the at least one second connecting portion.
