The utility model discloses a novel auxiliary tool for dismounting energy storage springs. The novel auxiliary tool for dismounting energy storage springs comprises two warping plates, a rotating rod and a supporting rod. The front end of each warping plate is provided with a flat cutting edge and a U-shaped opening so that the warping plates can be inserted in gaps of a spring before energy storage conveniently, and nuts are arranged at the rear ends of the warping plates, the nuts and the warping plates form an integrated structure. The thread direction of the upper portion of the rotating rod is the same as the thread direction of the nut of the upper warping plate, the thread direction of the lower portion of the rotating rod is the same as the thread direction of the nut of the lower warping plate, and the thread direction of the upper portion of the rotating rod is opposite to the thread direction of the lower portion of the rotating rod. The supporting rod is connected with the middle of the upper warping plate and the middle of the lower warping plate in a supporting point mode, adjusting nuts are arranged at the two ends of the supporting rod, and the length of the supporting rod can be adjusted so as to adapt to springs of different lengths. The novel auxiliary tool for dismounting energy storage springs is simple in structure, low in manufacturing cost, and fast and convenient to assemble and use, a large amount of maintenance time can be saved, power failure time is reduced, and the novel auxiliary tool for dismounting energy storage springs can be widely used for the field of spring dismounting of a substation and the like as an auxiliary tool.
