The invention relates to an anti-theft lock which comprises a lock shell, a lock cylinder and a high-violence-prevention stainless steel bar. Due to the fact that a springless structure and a child-mother ball structure are adopted, the technical unlocking difficulty is greatly increased, and the anti-theft performance of the lock is improved; and meanwhile, both the front and reverse faces of the lock can be used, and the old and the children can use the anti-theft lock conveniently.
