The invention relates to a prying prevention folding lock which comprises a cylinder and a folding chain formed by sequentially connecting strip-shaped folding pieces made of rigid materials end to end in a hinged mode. The cylinder is arranged at one end of the folding chain, and a plug matched with a lock hole in the cylinder is arranged at the other end of the folding chain. Due to the fact that only an inserting hole needs to be formed in the cylindrical face of the cylinder and seams do not exist on the periphery, no gap is left for a thief, strength is increased, the lock prying difficulty of the thief is increased, and the overall anti-theft performance of a lock body is improved.
