Winter heating automatic conversion device of self-starting diesel generating set

The utility model relates to the technical field of diesel generators, in particular to a winter heating automatic conversion device of a self-starting diesel generator set, which is characterized in that a magnetic spring capable of moving telescopically is arranged on the outer circular surface of a magnetic telescopic rod, so that any shape of an outer shell of the diesel generator can be accurately fixed; according to the diesel generator fixing device, the temperature adjusting machine capable of rapidly heating is fixedly arranged in the protective shell, and the movable heat-resistant elastic belt is arranged in the protective shell, so that all-directional dead-corner-free fixing of the diesel generator is achieved, and the stability in the heating automatic conversion process is further ensured. The temperature adjusting machine capable of rapidly heating is fixedly arranged in the protective shell, and then the diesel generator is preheated; therefore, high-precision uniform heating of different pos
