The invention discloses an asynchronous electrical and mechanical mixing shrapnel-free anti-theft alarm multi-locking lock. A connector of the lock hides in a hidden hole and is disconnected from a back lock cylinder. An expansion piece, a rotary block, a turn angle and a turntable lock a front lock cylinder. The front lock cylinder and the back lock cylinder are completely disconnected from an asynchronous rotary alarm device, and an electronic remote control device is invisibly installed in a power supply circuit of an electromagnet. The asynchronous electrical and mechanical mixing shrapnel-free anti-theft alarm multi-locking lock integrates electrical and mechanical interlocking invisibility, mechanical interlocking invisibility, front lock cylinder and the back lock cylinder connection invisibility and asynchronous alarm, and thieves cannot open the interlocking device or turn the back lock cylinder, or even if they damage the expansion locking portion and the connector portion through brute force, they can only turn the front lock cylinder but cannot turn the back lock cylinder. In addition, even if the thieves drill away both the front lock cylinder and the back lock cylinder through electric hand drills and turn the connection tongue through clips or other tools, the power supply circuit of the electromagnet cannot be connected as the turning contact does not contact the fixed contact; furthermore, the electronic remote control device interrupts the power supply circuit of the electromagnet, accordingly the safety latch cannot be opened, and the thorough anti-theft effect is achieved.
