The invention belongs to the electric system auxiliary tool field, and particularly relates to a multifunctional interface type insulation rod which can be used as a scale ruler, a high altitude electricity test rod, a long pole sickle, an wind meter and a mobile phone signal amplifier. The multifunctional interface type insulation rod comprises a drag hook type work head, an insulating bar and a grab handle, and thread holes and screws matched with the thread holes are arranged on the lower end face of the work head, the upper end face and the lower end face of the insulating bar and the upper end face of the grab handle. The multifunctional interface type insulation rod is characterized in that scale marks are engraved on the outer faces of the insulating bar and the grab handle, and the work head further comprises an electricity test rod work head, a sickle work head, a wind meter work head and a signal amplifier work head. According to the multifunctional interface type insulation rod, the functions of measuring height, testing voltage, cutting braches, measuring wind speed and amplifying mobile phone signals are added based on functions of a common insulation rod, and functional diversification of the multifunctional interface type insulation rod is achieved.
