Provided is an anti-theft lock with a key provided with a universal joint and a lock body provided with a bent hole. A limiter, the universal joint and a key handle are arranged at the rear part of the key, the variable-angle power transmission function of the universal joint device is utilized, and a designer selects a proper bent hole diameter according to the length and width of the key. The key, the limiter and the universal joint can penetrate into the bent hole in the unlocking process, the obtuse-angle-shaped front end of the key can be aligned with the lock hole and smoothly inserted into the lock hole, the key handle is rotated to drive the universal joint, the limiter and the key to rotate together, then the lock can be conveniently unlocked, due to the fact that the bent hole is formed, the unlocking difficulty is greatly increased, and a person skilled in unlocking cannot use the skill.
