A fixing mechanism includes a battery sleeve, a resilient member and a battery cover. The battery sleeve defines an open end to receive a battery. The battery sleeve includes a latching portion formed in an inner surface thereof adjacent to the open end. The resilient member is fixed to the inner side surface of battery sleeve. The battery cover includes a guide portion defined in an outer surface thereof, and a latching portion connecting with the guide portion. The battery cover is rotatably engaged with the battery sleeve via the open end. The latching protrusion slides along the guide portion until the latching protrusion is locked in the latching portion, and the resilient member presses the battery to resist the battery cover.
