A lens module includes a base to be fixed, a second elastic sheet fixed in the base, a lens sleeve sliding according to the base, a limiting member installed on the lens sleeve, a first elastic sheet, and an upper cover. The lens module includes a covering board with a central hole installed between the second elastic sheet and the lens sleeve. The diameter of the central hole is greater than the outer diameter of the lens sleeve. The covering board is connected to the base to fix the second elastic sheet on the base. Because the covering board to connect to the base, the second elastic sheet can be fixed on the base for decreasing time-consumption, reliable fixation, and decreasing the rate which the second elastic sheet rotates and is deformed.
