[0007] The fixed shaft of the above-mentioned rotating assembly mechanism moves in the guide groove of the arc guide rail, so that the movable plate can rotate relative to the fixed plate under the guidance of the guide groove and simultaneously realize a translational action on the linear guide rail assembly. The fixed plate and the movable plate are in an overlapping and flush state at both the starting and ending positions of the rotation.
[0008] According to a further optimized solution, the linear guide assembly includes a linear guide and a slider assembly slidably connected to the linear guide; the linear guide is fixed to the fixed plate, and the slider assembly is connected to one end of the central shaft. The slider assembly drives the central shaft to slide back and forth on the linear guide.
[0009] In a further optimized solution, the arc-shaped guide rail is provided with an arc-shaped guide groove, and the free shaft end of the fixed shaft is located in the guide groove. The guide groove defines the movement trajectory of the movable plate, ensuring the stability and reliability of the rotation and translation movement of the movable plate.
