The invention relates to a prying-resistant bolt which comprises a latch rack and a latch inserted into the latch rack, wherein a plurality of screw holes are uniformly distributed in the latch rack, and a latch handle is arranged on the latch; a locking piece is arranged on one side of the latch handle, and a buckling piece is arranged at one end of the locking piece. The buckling piece and the latch rack can be mutually buckled or loosened, and the cross-sectional area of the latch is reduced in sequence from left to right. As the cross-sectional area of the latch is reduced along with the extension direction of the latch, the latch is more easily inserted into the latch rack, the insertion and extraction efficiency of the latch is improved, and the service life of the latch is ensured. During use, as the locking piece and the buckling piece capable of being opening and closed by the latch rack are arranged on one side of the latch handle, when the latch is inserted into the latch rack, the buckling piece is buckled on the latch rack, so that the latch handle and the latch cannot move, and therefore the risk of prying is avoided.
