The invention relates to the technical field of electric power equipment, in particular to an imbalance-preventing supporting device for electric power equipment. The imbalance-preventing supporting device for electric power equipment comprises a bottom plate. Electric equipment is arranged between a clamping device and a first fixed block, a mounting groove is formed between two supporting blocks, a third spring is connected between two moving blocks, the upper ends of a first connecting rod and a second connecting rod are rotatably connected to a supporting plate through hinge pins, the other ends of first threaded rods penetrate a second shell, and a first threaded slide block and a second threaded slide block are in threaded connection to the outer sides of the first threaded rods. Byarranging a connecting rod, a moving wheel shrinks, so that the device is placed and moved conveniently. By arranging the spring, shock of the electric power equipment can be absorbed, and the electric power equipment is protected. By arranging the clamping device, the electric power equipment can be fixed to the supporting plate. The imbalance-preventing supporting device is simple in structure and convenient to use, and can protect the electric power equipment effectively.
