The friction force between the first friction member 300 and the second friction member 400 can enable the protective cover 200 to overcome the gravity of the protective cover 200, so that the protective cover 200 hovers on the support frame 100.

[0039] When the protective cover 200 needs to be moved, an external force is applied to the protective cover 200, and the external force is greater than the friction force between the first friction member 300 and the second friction member 400, thereby driving the protective cover 200 to move. After moving the protective cover 200 to a preset position, the external force is removed, and the protective cover 200 hovers on the support frame 100 by relying on the friction force between the first friction member 300 and the second friction member 400.
