The invention discloses a tooth-pushing-added asynchronous electromechanical hybrid anti-theft alarm lock. A connection body of the tooth-pushing-added asynchronous electromechanical hybrid anti-theft alarm lock is separated from a rear lock cylinder. The rear lock cylinder is locked through a locking head. A front lock cylinder is locked through an expansion piece, toothed rotating wheels, a rotating disc and a rotating corner, the front lock cylinder and the rear lock cylinder are completely separated and asynchronously rotate to give an alarm, and an electronic remote control device is installed in a power supply circuit of an electromagnet in a hidden mode. The electromechanical interlocking hiding, the mechanical interlocking, the connection hiding of the front lock cylinder and the rear lock cylinder and the asynchronous alarm are integrated, a thief can not open an interlocking device or rotate the rear lock cylinder, and the thief can only rotate the front lock cylinder and can not rotate the rear lock cylinder even after an interlocking portion and a self-locking portion are damaged by barbaric means. Even when the thief drills away the front lock cylinder and the rear lock cylinder through an electric hand drill and rotates a connection tongue part through tools such as clamps, the power supply circuit of the electromagnet can not be powered on due to the fact that a rotating contact does not make contact with a fixed contact; the power supply circuit of the electromagnet is powered off through the electronic remote control device, and therefore a safety lock catch can not be opened, and the thorough thievery prevention can be achieved.
