When the controller receives an unlocking signal (code scanning or other input signal) from the outside, for example, when a user scans a two-dimensional code to request the controller to unlock the lock, the controller controls the driving part 500 to drive the rotary dial 410 and the cam 420 to rotate in the second direction, and during the rotation process, the rotary dial 410 pushes the locking part 300 to rotate so that the hook 301 moves away from the card slot 201 until the hook 301 is separated from the card slot 201; specifically, after the locking slot 201 is released, the second resilient body 220 can drive the locking tongue component 200 to make the locking slot 201 away from the hook 301, and the locking tongue plate 210 stops at the unlocking position under the torque of the second resilient body 220 and the limiting action of the second limiting portion 240 until the cam 420 presses the first travel switch 700 in the rotary toggle mechanism 400, and the rotary toggle mechanism 400 stops rotating, thereby completing the unlocking action. In this process, the cam 420 presses the first stroke switch 700 to turn on the first stroke switch 700, and then the cam 420 continues to rotate, and when the cam 420 presses the first stroke switch 700 again, that is, the first stroke switch 700 is turned on for the second time, the controller controls the driving part 500 to stop rotating. During this time, the bolt assembly 200 rotates and moves away from the second travel switch 800, and the second travel switch 800 is open, at which time the controller receives an unlock signal.
