The invention discloses an asynchronous mechanical tooth pushing addition anti-theft lock. A rear lock cylinder of the anti-theft lock is completely disconnected from a front lock cylinder. The front lock cylinder is internally provided with a sliding hole, a specially-matched key hole and a hidden hole, a connecting body is installed in the hidden hole, and the connecting body is disconnected from the rear lock cylinder. The rear lock cylinder is internally provided with a lock hole and a connecting hole, and a connecting tongue at the rear end of the rear lock cylinder is connected with a linkage mechanism after penetrating through a passing hole and then is connected with a lock tongue. A lock head is arranged in front of a lock spring in a lock bearing hole, the lock head and an ejector column are installed in the lock hole, and a sliding rod in front of the ejector column is installed in an extruding groove and the sliding hole. The expanding end of an expanding sheet stretches in the extruding groove to lock the front lock cylinder, and a tooth pushing device and a rotating locking device lock the front lock cylinder. The anti-theft lock integrates mechanical interlocking, hiding and connecting hiding of the front lock cylinder and the rear lock cylinder, and a theft cannot open an interlocking device or rotate the rear lock cylinder. Even when the theft damages the interlocking, tooth runners and rotating corners with the brutal means, the theft can only rotate the front lock cylinder, the rear lock cylinder does not rotate, and theft prevention can be complete and thorough.
