The invention discloses a tooth pushing mechanical anti-theft lock. A rear lock cylinder and a front lock cylinder which are completely disconnected and a connecting body are hidden inside an invisible hole; a connecting hole is formed in the front side of the rear lock cylinder and a connecting bolt which is fixed at the rear side penetrates a passing hole; a sliding rod which is arranged in the front of a guiding spring inside a sliding hole is installed inside a sliding hole; the sliding rod is installed inside an expansion groove and the sliding hole; a shifting fork is fixed on the sliding rod inside the sliding groove through a connecting pin; an expansion end of an expansion piece is abutted against and presses inside a locking groove to lock the front lock cylinder; a tooth pushing device and a connecting locking device lock the front lock cylinder. The tooth pushing mechanical anti-theft lock adopts an oblique hanging direct pushing rotary type unlocking mode and integrates mechanical interlocking, invisibility and connection invisibility and accordingly a burglar cannot simultaneously open an external opening lock device and rotate the rear lock cylinder, namely, only the front lock cylinder can rotate and the rear lock cylinder does not rotate after the external opening lock device and a lock cylinder are damaged through barbaric means and prevention of burglary is completely achieved thoroughly.
