As shown in fig. 9, the first bracket 121, the second bracket 122, the third bracket 123 and the fourth bracket 124 are detachably disposed on the periphery of the side frame 112, and two ends of the fourth bracket 124 are respectively rotatably connected to one end of the first bracket 121 far away from the third bracket 123 and one end of the second bracket 122 far away from the third bracket 123. It is understood that the first and second brackets 121 and 122 are indirectly rotatably connected to the side frame 112 through the fourth bracket 124. The supporting assembly 120 further has a third supporting state and a fourth supporting state, and in the third supporting state, the first bracket 121 and the fourth bracket 124 can further rotate to a third preset angle relative to the back plate 111, wherein the second bracket 122 and the fourth bracket 124 can be kept folded in the side frame 112, and one end of the first bracket 121 and one end of the fourth bracket 124 can support the electronic device protective shell 100 laterally together with the first long side 1121; in a fourth supporting state, the second bracket 122 and the fourth bracket 124 may further rotate to a fourth preset angle relative to the back plate 111, wherein the first bracket 121 and the fourth bracket 124 may be kept folded on the side frame 112, and one end of the second bracket 122 and one end of the fourth bracket 124 may support the electronic device protective case 100 vertically together with the second short side 1124.

The above embodiments are only used to illustrate the technical solutions of the present application, and not to limit the same; although the present application has been described in detail with reference to the foregoing embodiments, it should 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; such modifications and substitutions do not substantially depart from the spirit and scope of the embodiments of the present application and are intended to be included within the scope of the present application.
