[0038] Therefore, in actual use, when the lock cylinder 4 is turned by the key, the protrusion 42 rotates with the lock cylinder 4 and rotates to contact the button 6. At this time, the circuit board receives the information transmitted by the button 6 and drives the alarm to be turned on, and the direction of the plane 42 of the lock cap 41 changes to limit the movement of the limiter 5. Therefore, when the alarm is turned on, if someone touches the handcuff lock, an alarm will be sounded, thereby better preventing theft.
[0039] And because it is all the rotation of the lock core 4 that drives the opening of the locking and the alarm to be synchronous, and the unlocking and the closing of the alarm to be synchronous, it can be achieved in one step, which is more convenient.
[0040] Secondly, a hole is also provided on the other side of the handle 1 so that the end of the movable cuff ring 3 can pass through the inner side of the handle 1 and then pass out.
