Telescopic electromechanical dual-control smart lock

A telescopic electromechanical dual-control smart lock, comprising:

• a lock cylinder mechanism, a transmission mechanism and a power supply control mechanism;
• wherein the lock cylinder mechanism comprises a bolt, a lock core PCB (printed circuit board) board, a positive electrode sheet, a negative electrode sheet and a first spring;
• the power supply control mechanism comprises a main control PCB board and a detachable battery;
• wherein the positive electrode sheet, the negative electrode sheet and the transmission mechanism are electrically connected with the lock core PCB board respectively;
• wherein a first end of the transmission mechanism is pressed against an end of the first spring;
• a second end of the transmission mechanism is fixedly connected with the bolt;
• when the first spring is pressed, the bolt is retracted, and when the first spring is expanded, the bolt is stretched out;
• the lock cylinder mechanism and the transmission mechanism are provided side by side, and the main control PCB board is electrically connected with the lock core PCB board and the detachable battery respectively.
