[0028] The rotating shaft 113 is provided with a threaded section, and the two rotating shafts 113 are arranged in parallel, and the threaded sections of the two rotating shafts 113 are threadedly connected with a synchronous linkage block 114. When one of the rotating shafts 113 rotates, the synchronous linkage block 114 moves along the threaded section, driving the other rotating shaft 113 to rotate, so that the rotating arms 115 on both sides rotate synchronously towards each other or synchronously rotate in the opposite direction.

When the two rotating support components 20 rotate to a certain angle range, they are automatically opened or closed, which is more labor-saving and improves the user experience.
