Combined intelligent electric meter and combination method thereof

The invention relates to the technical field of combined intelligent electric meters, in particular to a combined intelligent electric meter and a combination method thereof. Thecombined intelligent electric meter comprises a plurality of electric meter bodies, the plurality of electric meter bodies are detachably connected, the left side of each electric meter body is provided with an adaptive groove, and the right side of each electric meter body is fixedly connected with an adaptive frame body. An adaptive frame body is moved towards an adaptive groove, when an elastic clamping rod is in contact with the inner wall of an insertion groove, one end of the elastic clamping rod downwards extrudes the inner wall of the insertion groove, meanwhile, a sliding seat drives a U-shaped clamping block to retract towards the interior of a movable opening through a connecting strip, and when a transverse strip at the bottom of a connecting transverse rod moves to the position over the U-shaped clamping block, the elasti
