An exemplary support structure includes a support body, a connecting body, and a rear board. The connecting body is fixed on the support body. The rear board is rotatable relative to the support body. The rear board defines a through hole therein. The connecting body forms a latch protrusion. When the support body is located at a first position, the latch protrusion is capable of passing the through hole of the rear board. When the support body and the latch protrusion are located at opposite sides of the rear board, and the support body rotates past the first position, the latch protrusion resists the rear board and prevents the support body detaching from the rear board.
