When the 503a moves toward the fourth spring 405e, the fourth spring 405e acts forcefully on the trigger blocks 503a-42, so that the flip card 503a-4 is in the engaging position, and when the first sliding block 503a moves toward the direction of the third spring 405d , the third spring 405d exerts force on the trigger block 503a-42 to make the flip card 503a-4 in the non-engaging position. It should be noted that the end position of the third spring 405d corresponds to the distance a from the first position, and also That is, when the second sliding block 503b is at the shortest position on the first sliding block 503a, and the second push plate 503c-2 is in contact with the first baffle plate 503c-1, the trigger block 503a-43 is in contact with the third spring 405d and the third spring 405d. The neutral position of the four springs 405e in their natural state.

To sum up, when the shutter 404 is to be closed, the shutter 404 is rotated so that the lock head 501 enters the lock box 405 through the lock hole 504. At this time, the first sliding block 503a is at the initial position, and the second sliding block 503b is relative to the lock box 405. The first sliding block 503a is in the longest position, the second push plate 503b-1 is in contact with the first baffle plate 503c-1, the second baffle plate 503c-2 is in contact with the support plate 502a, and the claws 503b are in an open state; The three springs 405d are in a compressed state, and push the trigger blocks 503a-42 to make the flip card plate 503a-4 in a non-engaging position.

It should be noted that the second spring 405b is also in a stressed state at this time, and acts on the first sliding block 503a together with the third spring 405d to achieve a force balance.

After the lock head 501 enters the lock box 405, it first comes into contact with the first push plate 503b-1, and pushes the first sliding block 503a to move away from the initial position, and the second sliding block 503b follows the movement. It does not affect the inward movement of the lock head 501 and the first push plate 503b-1, and then the lock head 501 and the first push plate 503b-1 move to contact the first baffle 503c-1, and continue to push the push rod 502c to move, moving When the push rod 502c is in the second position, the claws 502b are closed.

At this time, the force on the baffle 404 is removed, the baffle 404 will return under the action of the torsion spring, so the lock head 501 will move to the position of the lock hole 504, and the first sliding block 503a is also under the action of the second spring 405b Follow the lock head 501 to return. Since the second sliding block 503b is at the longest position relative to the first sliding block 503a during this process, and the distance c is greater than the distance a, the second push plate 503b-1 is not in contact with the first block during the returning process of the first sliding block 503a.
