Electronic lock and use thereof

An electronic lock comprising:

• a lock shell, having a first lock hole and an insertion hole;
• a rope winded disc, disposed inside the lock shell, wherein a lock rope is winded at the rope winded disc, and the lock rope is operatively pulled out from the rope winded disc or returns inside the rope winded disc;
• a lock rope head, inserted into the insertion hole and connected with one end of the lock rope;
• a sliding lock block, disposed inside the lock shell through a spring, wherein one end of the sliding lock block is placed in the first lock hole;
• and
• a controlling and driving device, disposed inside the lock shell, wherein when locking is required, a user pulls out the lock rope head from the insertion hole, the lock rope head is inserted into the first lock hole after the lock rope is pulled out from the rope winded disc, and the sliding lock block locks the lock rope head;
• and
• when unlocking is required, the controlling and driving device drives the sliding lock block to slide in an opposite direction, the user pulls out the lock rope head from the first lock hole, and the sliding lock block returns to an original position through the spring;
• wherein the controlling and driving device comprising:
• a sensor, disposed inside the lock shell;
• a printed circuit board, disposed inside the lock shell and electrically connected with the sensor;
• and
• a motor, disposed inside the lock shell and electrically connected with the printed circuit board, wherein during usage, when the lock rope head is inserted into the first lock hole, the sensor detects that the lock rope head is locked and feeds back a result;
• and when the printed circuit board receives an unlock instruction, the printed circuit board controls the motor such that the motor drives the sliding lock block to slide in the opposite direction for unlocking.
