The invention discloses a mechanical asynchronous gear pushing anti-theft lock. A rear lock cylinder and a front lock cylinder of the mechanical asynchronous gear pushing anti-theft lock are completely separated. A connection body of the mechanical asynchronous gear pushing anti-theft lock is hidden in a hidden hole. The front lock cylinder is locked through an expansion piece. A lead hole, a specially-matched key hole and the hidden hole are formed in the front lock cylinder. The connection body is arranged in the hidden hole and separated from the rear lock cylinder. A connection hole is formed in the front face of the rear lock cylinder. A connection spring bolt is fixed to the rear face of the rear lock cylinder and penetrates through a passing hole. A slide rod is arranged in front of a lead spring in a slide hole and is installed in the slide hole. The slide rod is installed in a squeezing groove and the slide hole. A squeezing block is embedded in the slide rod in the squeezing groove. The front lock cylinder is locked in the squeezing groove through the expansion end of the expansion piece. The front lock cylinder is lock through a gear pushing device and a connection and locking device. The mechanical interlocking, hiding and the connection and hiding of the front lock cylinder and the rear lock cylinder are integrated, and the situation that a thief opens an inner supporting and locking part and rotates the rear lock cylinder at the same time can not happen. The thief can only rotate the front lock cylinder but can not rotate the rear lock cylinder even after the inner supporting and locking part and a lock column are damaged through barbaric means, and the complete and thorough thievery prevention can be achieved.
