when the movable plate 61 moves upwards under the driving of the roof base 1, the movable plate 61 can rotate around the second sphere 62, so that the relative horizontal state is maintained, along with the continuous deflection of the roof base 1, when the side, far away from the lifting direction of the roof base 1, of the movable plate 61 is in contact with the strip-shaped plate 67, the movable plate 61 starts to deflect upwards along with the roof base 1 due to the blocking of the strip-shaped plate 67, at the moment, the counterweight balls 10 in the two hollow plates 9 adjacent to each other in the lifting direction start to roll in the opposite direction due to gravity, and after the roof base 1 stops deflecting, the counterweight balls 10 stay at the current position under the action of gravity and play a counterweight role, so that the movable plate 61 can better maintain balance;

when the roof base 1 is in the process of restoring to the original position, the counterweight balls 10 can return to the symmetrical center of the hollow plate 9 under the action of gravity, so that the movable plate 61 can be quickly restored to the original position and maintain a relatively stable horizontal state under the action of the counterweight balls 10.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
