A casing of a mobile device includes a front casing and a back casing. The front casing includes a column and at least two detent hooks. The back casing includes a protruding part and an actuating part. The protruding portion includes at least two fasteners. The actuating part is disposed in the hole and includes at least two cantilevers. The cantilevers are connected to the fasteners respectively. When an external force is applied to the actuating part, the cantilevers push the fasteners to get away from the detent hooks, so that the detent hooks are detached from the snapping parts. Therefore, the front casing and the back casing can be quickly assembled or disassembled. |
