In another embodiment, as shown in fig. 9, the annular light guide plate 740 is provided with an adhesive overflow slot 743, the annular light guide plate 740 is connected to the panel 730 through a connection adhesive disposed in the adhesive overflow slot 743, referring to fig. 2, the mounting base 100 has a central line a perpendicular to the first rotating shaft 300, the adhesive overflow slot 743 and the sleeving member 810 are sequentially disposed in a direction of the central line a, and the adhesive overflow slot 743 and the sleeving member 810 are located at two sides of the center of the mounting base 100. Adopt this embodiment, glue through overflowing the interior connection of gluey groove 743, further connect the position that first pivot 300 was kept away from to annular light guide plate 740 and panel 730, avoid panel 730 perk and lead to panel 730 to be connected untight condition with annular light guide plate 740, be favorable to promoting connection stability. Alternatively, the mounting base 100 has a circular structure, and a center line a perpendicular to the first rotating shaft 300 passes through a center of the mounting base 100, and a center of the mounting base 100 is the center of the mounting base 100.

While the present embodiments have been described with reference to the accompanying drawings, it is to be understood that the present embodiments are not limited to those precise embodiments, which are intended to be illustrative rather than restrictive, and that various changes and modifications may be effected therein by one skilled in the art without departing from the scope of the appended claims.
