Since the protrusion post 311 and the sync support plate 31 are integrated, the sync support plate 31 also moves with the screen support plate 2. The two synchronous support plates 31 are meshed with the middle gear set 4 through the gear 313, so that the first shell 04 and the second shell 05 can move synchronously;

the damping block 321 is sleeved outside the protruding column 311, when the synchronous support plate 31 moves along with the screen support plate 2, the protruding column 311 slides from one side of the screen support plate 2 to the other side, at this time, the damping block 321 sleeved in the mounting hole 312 of the synchronous support plate 31 is pressed by the pressing surfaces 212 on the two sides of the screen support plate 2, the pressed damping block 321 moves in the mounting hole 312 of the synchronous support plate 31 in the direction away from the synchronous slide rail 211, at this time, the damping elastic member 322 is pressed, the positive pressure of the damping elastic member 322 increases the positive pressure of the damping block 321 and the pressing surface 212, so that the friction force between the damping pressing surface a of the damping block 321 and the pressing surface 212 of the screen support plate 2 increases, and the hovering effect is achieved, as shown in fig. 19 to fig. 20.

The structure shown in fig. 21 is formed when the first housing 04 and the second housing 05 are completely folded, and correspondingly, the structure shown in fig. 1, 22 and 23 is formed when the first housing 04 and the second housing 05 are completely unfolded.
