The utility model relates to a portable high-frequency heating detacher. According to the structure of the portable high-frequency heating detacher, the output end of a high-frequency current heater is connected with a heating coil through a high-frequency lead. According to the structure of the high-frequency current heater, a rectifier is connected with a direct current filter, the direct current filter is connected with an inverter, and the inverter is connected with an output circuit. By the utilization of the high-frequency eddy current principle, high-frequency current is made to generate high-frequency magnetic flux around the heating coil, so that the temperature of part of a heated bolt rises rapidly, and the bolt expands and loosens; rust and paint are heated and calcified, and then the bolt can be detached easily.
