One end of the rotating member 30 is provided with a rotating shaft 31, the rotating member 30 is rotatably mounted in the rotating hole 221 through the rotating shaft 31, and a pair of rotating members 30 are disposed opposite to each other.

When the rotating assembly 100 is used for connection, the shaft body 11 of the connecting shaft 10 is connected to the first member (for example, the operating handle 300), and the rotating member 30 is connected to the second member (for example, the display screen 200). When the rotating base 20 rotates around the axis of the connecting shaft 10, the display screen 200 can be driven to rotate around the axis of the connecting operation handle 300, that is, the display screen 200 can rotate around the axis a shown in the figure.
