The utility model discloses an automatic boxing paw for single-phase and three-phase electric energy meters. The automatic boxing paw comprises a support and grabbing units arranged on the support. Each grabbing unit comprises a limiting air cylinder, a clamping air cylinder, a first movable finger, a second movable finger and a fixed finger, wherein the first movable finger, the second movable finger and the fixed finger are arranged in a triangular shape and used for grabbing one electric energy meter, and the limiting air cylinder is used for limiting the stretchable range of the first movable finger and the stretchable range of the second movable finger. According to the automatic boxing paw, the grabbing units arranged on the support are adopted for automatically grabbing the electric energy meters, and the requirement for grabbing the electric energy meters of different types is met; meanwhile, the multiple grabbing units are arranged at the same time to grab two three-phase electric energy meters at a time or grab four single-phase electric energy meters at a time, the number of varieties of paws is decreased, the requirement for replacing paws during different electric energy meter grabbing is avoided, it is ensured that the two electric energy meters of the different models can be rapidly switched on the same production line, and the equipment general performance and the utilization rate are improved.
