When the detecting tongue 205 is located at the first position, the detecting tongue 205 partially extends out of the lock case, and when the object to be locked 50 is closed, the extending portion of the detecting tongue 205 is pressed by the fixture to slide to the second position, and the third switch 207 is triggered.

That is, in the absence of other external forces, the elastic force provided by the elastic member 206 forces the detecting tongue 205 to move to the first position and keeps the detecting tongue 205 at the first position, i.e., a portion of the detecting tongue 205 extends out of the lock case, and illustratively, one end of the detecting tongue 205 forms a spherical surface S205, and in the first position, the one end of the detecting tongue 205 extends out of the lock case. When the locked object 50 is closed, for example, when the door body is closed, the one end (spherical surface S205 portion) on the detecting tongue 205 is pressed by the door frame, so that the detecting tongue 205 moves to the second position, at this time, the other end of the detecting tongue 205 triggers the third switch 207 in the lock case, when the detecting tongue 205 leaves the second position again, the third switch 207 can generate a trigger signal, and the trigger signal can be used as a determination signal for determining that the locked object 50 is closed. When the control circuit board 402 receives the trigger signal of the third switch 207, it indicates that the locked object 50 is closed, and at this time, the control circuit board 402 controls the driving motor 403 to operate according to the trigger signal, and the driving motor 403 drives the lock lever 30 to rotate around one direction, so that the lock tongue 203 extends out and is automatically locked, thus, it can be ensured that locking is performed only when the locked object 50 is completely closed (in place), and the situation that the lock tongue 203 is locked due to false locking or dislocation during locking is avoided.
