An electronic device includes a lens assembly, a lens focusing rod, a power switch and a lens protective cover. When the lens protective cover is located in the first position, the lens assembly is shielded by the lens protective cover, the power switch is turned off, and the lens protective cover is separated from the lens focusing rod. When the lens protective cover is located in the second position, the power switch is turned on, and the lens protective cover is contacted with the lens focusing rod. When the lens protective cover is moved between the second position and the third position, the power switch is turned on, and the lens assembly is driven by the lens protective cover through the lens focusing rod for focusing operation. |
