[0073] Furthermore, in this embodiment, the fifth support member 225 is slidably connected to the first bracket 212 and the second bracket 213, thereby limiting the fifth support member 225 to only be able to slide linearly perpendicular to the fixed bracket 210, thereby preventing the fifth support member 225 from moving in other directions; the fifth support member 225 is connected to the first bracket 212 through a first elastic member (not shown in the figure), and when the support mechanism 220 is in the folded state or the flat state, the first elastic member is in an elastic deformation state, that is, the first elastic member generates a pulling force that causes the fifth support member 225 to move toward the first bracket 212.

[0074] In this embodiment, the first elastic member includes but is not limited to a spring. It should be noted that the fifth support member 225 is connected to the first bracket 212 via the first elastic member for illustrative purposes only. This embodiment does not impose any specific restrictions on the connection method between the fifth support member 225 and the first bracket 212. For example, the fifth support member 225 includes a magnetic member, the first bracket 212 includes a magnetic member, and the fifth support member 225 is magnetically connected to the first bracket 212 via the magnetic member and the magnetic member. It is understood that the positions of the magnetic member and the magnetic member can be interchanged.
