The first casing unit has a first outer moisture-proof structure disposed around its outer side. The first casing unit has a first receiving room, a second receiving room, and an opening communicating between the second receiving room and the external environment. The second casing unit is mated with the first casing unit. The second casing unit has a second outer moisture-proof structure and a first moisture block, and the first outer moisture-proof structure and the second outer moisture-proof structure are mated with each other. The first movable structure has a first movable element mated with the first moisture block. The push structure passes through the opening in order to selectably push the first movable element.
