The invention discloses a mechanical side locking antitheft lock. A rear lock cylinder is completely disconnected with a front lock cylinder, a connecting body is hidden in an invisible hole, an expanding piece and a locking column lock the front lock cylinder, a guide hole, a specially-matched key hole and the invisible hole are formed in the front lock cylinder, the connecting body is disconnected with the rear lock cylinder, a connecting hole is formed in the front face of the rear lock cylinder, a connecting tongue penetrating via hole is fixed in the rear face of the rear lock cylinder, a sliding rod is arranged in front of a guide spring in a sliding hole and mounted in the sliding hole, the sliding rod is mounted in an expanding groove and the sliding hole, an expanding end of an expanding end jacks and presses in a locking groove to lock the front lock cylinder, and a side locking device locks the front lock cylinder. The mechanical side locking antitheft lock integrates mechanical interlocking, hiding and connection hiding of the front and rear lock cylinders, so that a thief cannot open an outwards-expanding lock head and rotate the rear lock cylinder at the same time; even if the outwards-expanding lock head and a locking column are damaged by a barbaric means, only the front lock cylinder can be rotated, and the rear lock cylinder cannot be rotated, so that antitheft effect is realized completely and thoroughly.
