An anti-theft lock comprises a lock body, a lock cylinder, a key, a spring and the like. Guide pieces and a central shaft are arranged in the lock cylinder. The key is shaped like a comb, and teeth of the key are as many as the guide pieces. Each guide piece is a rectangular metal piece, one end or two ends of each guide piece are provided with a small, long and narrow rectangular extending end, a rectangular guide groove is formed in each metal piece, and a hollow round hole is formed in each rectangular guide groove. The positions of the round holes in the respective guide grooves are different, and the diameter of the round holes is larger than the width of the guide grooves. Two rows of symmetrical fixing grooves are formed in the outer circle of the central shaft. When the lock is not opened as shown in picture 2, the guide pieces are matched with the fixing grooves in the central shaft. At the moment, as each guide piece is located in an independent position, if only the hollow round hole in one guide piece is not located in the axis of the central shaft, the central shaft will be clamped in the corresponding fixing groove and can not move leftwards and rightwards, and the lock can not be opened. Therefore, the anti-theft lock has an anti-theft function.
