In this implementation manner, the thickness of the first folding portion 120 is equal to the thickness of the first rotating arm 121 .

Taking the electronic device shown in FIG. 2 as an example, the first rotating shaft 160 can also be a double-rotating central rotating shaft to connect the first folding part 120 and the second folding part 130, such as the double rotating shaft described in FIGS. 6 and 7 . Center shaft.

Figures (a), (b) and (c) in Figure 6 are respectively the expanded state, folded state and exploded view of the two folding parts connected by the double rotation center shaft. As shown in FIG. 6, the first rotating shaft 160 includes two rotation centers, that is, a first rotation center 160a and a second rotation center 160b.
