When an emergency occurs, the control button 9 is pressed. At this time, the signal transmitting module on the main control circuit board 8 sends a signal to the signal receiving module on the lock control circuit board 12. When the lock control circuit board 12 receives the signal, it discharges the conductive wire 13, so that the conductive wire 143 is in a short-circuit state. The conductive wire 13 is a titanium alloy conductive wire, which will shrink when it is short-circuited, and then pulls one end of the second lock tongue 16 to rotate the second lock tongue 16. When the second lock tongue 16 rotates, the other end thereof rotates along the direction of the second arc-shaped rib 39, so that the clamping portion 35 of the first lock tongue 15 is disengaged from the clamping step 34 of the second lock tongue 16. Under the action of the first torsion spring 31, the first lock tongue 15 rotates along the direction of the first arc-shaped rib 38, prompting the lock buckle 17 to disengage from the locking groove 36 and the lock buckle rod 37 of the first lock tongue 15. At this time, the lock control box 2 is promptly disengaged from the traction ring on the children's bracelet, strap, school bag or pet. After the lock buckle 17 is disengaged from the first lock tongue 15, under the action of the second torsion spring 26, the second lock tongue 16 is automatically reset. When the lock buckle 17 needs to be used again, the lock buckle 17 is inserted, and the first locking tongue 15 is reset under the pressure of the lock buckle 17. During the resetting process of the first locking tongue 15, with the cooperation of the arc surface 41 of the first locking tongue 15 and the inclined surface 42 of the second locking tongue 16, the second locking tongue 16 will automatically rotate until the clamping portion 35 of the first locking tongue 15 is clamped on the clamping step 34 of the second locking tongue 16 again. At this time, the other end of the lock buckle 17 is re-located in the locking groove 36 and hooks the lock buckle rod 37.
[0028] The above is only a specific implementation of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
