The invention discloses a weak explosion destroyer support. The weak explosion destroyer support comprises lifting type stand bars, a center barrel, lifting type springs, foldable cantilevers, a weak explosion destroyer fixing shell and a weak explosion destroyer fixing shell top cover. A lifting type foldable stand bar structure is adopted in the support, the adaptation capability and stability of the supports to different terrains are enhanced, and carrying, storing and conveying are convenient. The foldable cantilevers are adopted, and the equipment storage size can be reduced. Meanwhile, the equipment operation distance can be increased, and the survival capability of the weak explosion destroyer support can be effectively improved. The universal support and a scaleplate structure are adopted, the direction of a weak explosion device is guaranteed, the height of burst is convenient to determine and fix, and the destroying effect is ensured. The targets that positioning, orienting and fixed explosion height are accurate, operation and usage are convenient, reliability is high, and adaptability is high can be achieved; and the arranging efficiency is improved, and the fixing requirement on a weak explosion destroyer during weak explosion waste ammunition destroying is met. The device portable, easy to operate and capable of accurately determining the explosion height and direction is provided for the weak explosion waste ammunition destroying work.
