wherein the clamping mechanism comprises several clamping components electrically connected to the control circuit board, the clamping components abut against an outer circumference of the lock cable, the clamping components and the lock cable are electrically connected; and

wherein when the lock cable is inserted from the locking insertion opening to contact the clamping components and continue to be inserted along an insertion direction, the lock cable is capable of driving the clamping mechanism to reduce the clamping force of the clamping components on the lock cable, so that the lock cable is capable of moving based on the clamping mechanism in the insertion direction;

wherein the clamping mechanism further comprises an elastic component and a movable base, the movable base is arranged in the pressing cavity, the clamping component is movably arranged on an upper end of the movable base, the elastic component is arranged between the housing and the movable base, and the elastic component drives the upper end of the movable base to approach the insertion opening; and

wherein when the clamping component is at a preset position of the narrowing part, the narrowing part is capable of forcing the clamping component to abut against the outer circumference of the lock cable.

2. The electronic tag lock of claim 1 , wherein when the clamping component abuts against the outer circumference of the lock cable, the lock cable is driven in an opposite direction of the insertion direction of the lock cable, and the lock cable will drive the clamping component to move, to increase the clamping force of the clamping component on the lock cable, so that the lock cable cannot be pulled out of the clamping mechanism in this direction.

3. The electronic tag lock of claim 1 , wherein metal balls are configured as the clamping components.

4. The electronic tag lock of claim 1 , wherein metal balls are configured as the clamping components.

5.
