The invention discloses a mechanical asynchronous theft-proof lock with a side lock. According to the mechanical asynchronous theft-proof lock with the side lock, a rear lock core and a front lock core are completely disconnected, a connector is hidden in an invisible hole, and an expanding sheet locks the front lock core; a lead hole, a special key hole and the invisible hole are formed in the front lock core, the connector is arranged in the invisible hole, and the connector is disconnected with the rear lock core; a connecting hole is formed in the front of the rear lock core, and a hole through which a connecting tongue passes is fixed in the back surface; a slide bar is arranged at the front of a guide spring in a slide hole, the slide bar is arranged in the slide hole, the slide bar is arranged in an extrusion groove and the slide hole, an extrusion block is embedded in the slide bar in the extrusion groove, the expanding end of the expanding sheet dead locks the front lock core in the extrusion groove, and a side lock device and a connection lock device dead lock the front lock core. The mechanical asynchronous theft-proof lock with the side lock integrates mechanical interlocking, invisibility and front and rear lock core connecting invisibility, a thief cannot simultaneously open an inner support lock and rotate the rear lock core; even if the inner support lock and a lock post are damaged by a barbaric way, the thief can only rotate the front lock core, the rear lock core cannot be rotated, and the complete theft-proof effect is realized.
