The invention discloses an irregular hole leaking stoppage device which comprises a bolt rod, a plurality of jaw blocks, a conical plug, an inner pressing rubber block, an outer pressing rubber block, an outer pressing plate and a fastening nut. The conical plug is fixed to the end of the bolt rod. The jaw blocks are evenly fixed to the plug. The inner pressing rubber block, the outer pressing rubber block and the outer pressing plate are each provided with a through hole matched with the bolt rod. The bolt rod penetrates through the inner pressing rubber block, the outer pressing rubber block and the outer pressing plate in sequence. The inner pressing rubber block is tightly attached to the conical plug. The fastening nut is in threaded connection with the bolt rod. The fastening nut is tightly attached to the outer pressing plate. The irregular hole leaking stoppage device can be easily inserted into a leaking hole through the jaw blocks, and operation is convenient and fast; two stoppage devices, namely the inner pressing rubber block and the outer pressing rubber block are arranged, the deformation plane is unfolded and expanded after the inner and outer pressing rubber blocks are squeezed, and leaking holes of irregular shapes and dissimilar sizes can be blocked.
