An electronic device includes a housing and a mounting apparatus. The mounting apparatus is received in the housing. The mounting apparatus includes a casing and an operating assembly. The casing includes a front wall defining a slot. The operating assembly is received in the casing, and includes a handle, an elastic member, and an operating plate. The handle is pivotably connected to the casing. A portion of the handle can extend out of the casing through the slot by rotating the handle. The elastic member provides an elastic force to rotate the handle to make the portion of the handle extend out of the casing. The operating plate is slidably connected to the front wall, and can cover the slot to limit the portion of the handle from extending out of the casing and uncover the slot to allow the portion of the handle from extending out of the casing.
