The invention discloses a mechanical interlocking toothed push antitheft lock. The mechanical interlocking toothed push antitheft lock is characterized in that a rear lock cylinder of the mechanical interlocking toothed push antitheft lock is completely disconnected from a front lock cylinder, and the front lock cylinder is locked by an expansion sheet; a slide bar is arranged in a slide hole in the front lock cylinder, a connecting body is mounted in a concealment hole, and a squeezing block is fixed onto the slide bar; a connecting hole is formed in the front of the rear lock cylinder, and a connecting bolt is fixed to the rear of the rear lock cylinder and penetrates a via hole; the slide bar is arranged at the front of a guide spring in the slide hole, is mounted in the slide hole and is mounted in a squeezing groove and the slide hole, the squeezing block is embedded in the slide bar in the squeezing groove, the front lock cylinder is locked in the squeezing groove by an expansion end of the expansion sheet and is locked by tooth push devices under rotary locking effects. The mechanical interlocking toothed push antitheft lock has the advantages that mechanical interlocking, concealment and front and rear lock cylinder connection concealment functions are integrated with one another, so that thieves cannot destroy inner support locking effects and drive the rear lock cylinder to rotate simultaneously; only the front lock cylinder can rotate while the rear lock cylinder does not rotate even after the inner support locking effects and a connecting body portion are destroyed by barbaric means, and accordingly thorough antitheft effects can be realized.
