The specific use process of the classical key lock of the embodiment is as follows:

when the bag body is connected with the bag cover, the first connecting mechanism 20 is connected with the second connecting mechanism 30, as shown in fig. 8, the insert block 24 is inserted into the accommodating cavity through the inlet/outlet 31, the insert hook 71 is in the locking position and is inserted into the hook groove 241 of the insert block 24, the first elastic element 81 and the second elastic element 82 are both in the free state, and the ball 94 of the ball assembly 92 is inserted into the first arrival groove 912; the driving groove 911 is aligned with the second hole portion 522 of the insertion hole 52.

When the first connecting mechanism 20 and the second connecting mechanism 30 are switched from the connecting state to the disconnecting state, the key 10 passes through the insertion hole 52 and enters the accommodating cavity to be inserted with the positioning rod 44, and under the guiding action of the insertion hole 52, the lock rod of the key 10 enters the driving groove 911 and contacts with the driving curved surface 621 of the driving hole 62; then the key 10 is rotated clockwise, the push block 12 moves along the direction that the curvature of the driving curved surface 621 becomes smaller under the guiding action of the driving curved surface 621, the push block 12 pushes the sliding block 60 to move in the direction away from the inlet/outlet 31 against the resistance of the first elastic member 81, when the push block 12 contacts the moving block 91, the push block 12 pushes the moving block 91 to move in the direction from the second arrival groove 913 to the first arrival groove 912, when the impact sound is heard, the rotation of the driving key 10 is stopped, at this time, the ball 94 has moved from the first arrival groove 912 to the second arrival groove 913, and at the same time, the insertion hook 71 moves to the unlocking position which is separated from the hook groove 241, and at this time, the connection state of the first connection mechanism and the second connection mechanism is as shown in fig. 9; thereafter, the insert block 24 of the first linkage 20 is removed from the second linkage 30, whereupon the connection between the first linkage 20 and the second linkage 30 is released and the wearer can flip the flap away from the opening of the bag body and remove the product from the bag body.

When the first connecting mechanism 20 and the second connecting mechanism 30 are switched from the disconnected state to the connected state, the inserting block 24 is inserted into the accommodating cavity, and then the key 10 is inserted into the driving curved surface 621 to contact; then, the key 10 is driven to rotate counterclockwise, the pushing block 12 moves along the direction of increasing curvature of the driving curved surface 621 under the guiding action of the driving curved surface 621, at this time, the pushing block 12 is moved away from the sliding block 60, the first elastic element 81 acts to push the sliding block 60 to move towards the direction of the access 31, so that the sliding block 60 is away from the insertion hook 71, the second elastic element 82 drives the insertion hook 71 of the rotating rod 70 to move towards the access 31, while the pushing block 12 pushes the moving block 91 to move toward the first arriving slot 912 to the second arriving slot 913, when the striking sound is heard, the rotation of the drive key 10 is stopped, at which time the balls 94 have moved from the second reaching-position groove 913 into the first reaching-position groove 912, meanwhile, the insertion hook 71 moves to the locking position and is inserted into the hook groove 241, so that the connection between the first connecting mechanism 20 and the second connecting mechanism 30 is completed, and the contents in the bag body can be prevented from being discharged from the bag body when the articles are not taken.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
