The invention discloses an asynchronous and mechanical tooth pushing anti-theft lock. According to the asynchronous and mechanical tooth pushing anti-theft lock, a rear lock cylinder and a front lock cylinder are completely disconnected; a sliding hole, a special matched key hole and an invisible hole are formed in the front lock cylinder, and a connector is installed in the invisible hole, and disconnected with the rear lock cylinder; a locking hole and a connecting hole are formed in the rear lock cylinder, and a connecting bolt at the rear end of the rear lock cylinder is connected with a linkage mechanism after penetrating through a through hole, and then is connected with a locking bolt; a locking head is arranged in front of a locking spring in a locking carrying hole, the locking head and a jacking column are installed in the locking hole, and a sliding rod in front of the jacking column is installed in an extrusion groove and the sliding hole; the expansion end of an expansion sheet stretches into the extrusion groove to lock the front lock cylinder, and the front lock cylinder is locked by a tooth pushing device and a connecting locking device. According to the asynchronous and mechanical tooth pushing anti-theft lock, mechanical interlocking, invisibility, and connecting invisibility of the front lock cylinder and the rear lock cylinder are integrated, and a thief cannot unlock an interlocking device or rotate the rear lock cylinder; even though interlocking and a lock column are damaged by savage means, the thief can only rotate the front lock cylinder, the rear lock cylinder cannot be rotated, and therefore thievery prevention can be achieved completely and thoroughly.
