Electronic digital display component structure for dual-purpose battery

The utility model relates to an electronic digital display component structure for a dual-purpose battery. The electronic digital display component structure comprises an outer housing, a circuit board and two batteries in different sizes, wherein the tops of the batteries are in contact with a battery cover; the bottoms of the batteries are in contact with a cathode welded on the circuit board; and a battery jacket is embedded into the outer housing and can be detached to be welded on a battery positive plate and a battery negative plate on the circuit board according to different needs. During specific application, when the 3V battery with larger diameter is in use, the battery jacket is dismounted; and when the 1.5V battery with smaller diameter is in use, the battery jacket is mounted. As the 3V battery has a larger diameter but a smaller height than the 1.5V battery, and the battery cover adopts a locally slotted structure, both of the two batteries can be put into use. The electronic digital display com
