The invention discloses electricity meter mounting and power connecting multifunctional pliers. The electricity meter mounting and power connecting multifunctional pliers comprise a first connecting piece and a second connecting piece. The size of the first connecting piece is the same as that of the second connecting piece. A hinge pin is arranged between the middle portions of the first connecting piece and the second connecting piece in an inserting mode. One end of the hinge pin sequentially penetrates through the second connecting piece and the first connecting piece. A third outer threadis arranged at the end, located above the first connecting piece, of the hinge pin. A nut is in threaded connection with the end, located above the first connecting piece, of the hinge pin. A first moving disc with a screwdriver and a second moving disc with a test pencil are respectively arranged in the first handle and the second handle, cutting blades are arranged in clamping blocks, and therefore when a worker assembles and disassembles an electricity meter, tools are not required to be carried in a toolbox, and convenience is achieved. The first connecting piece and the second connectingpiece are connected by the hinge pin and the nut, and therefore the pliers can be disassembled and used based on requirements.
