▎ 摘 要
NOVELTY - The utility model claims a graphene battery with warning function, wherein its structure comprises an upper snap ring, a graphene battery block, an electrode column, a lithium battery casing, a connection bracket, an electrical connection piece, a connection column, a warning cover; the upper snap ring and the lithium battery casing are integrally molded; when the warning ring on an electric rod is on the same plane as the inner bottom edge of upper support casing, it means that the electric rod and the electrode column are in good contact together, so that the power can be transmitted normally; when not in use, reversing the protective casing ring can separate it from the electrode column, so that the electric rod is again inside the protective casing ring, while the outer wall of the protective casing ring and the inner wall of the protective ring are smooth, ensuring that the friction force is minimized during rotation, which can effectively protect the electric rod and prevent the electric rod from being exposed to the outside for a long time to oxidize with oxygen, causing poor contact problem.
