Embodiment 3
[0084] This embodiment describes in detail the process of opening and closing the door.
[0085] When opening the door, the specific process is as follows:
[0086]The operator rotates the inner handle 209 clockwise, because the inner handle 209 is connected with the second gear 204 through the first shaft 206, the rotating inner handle 209 will drive the second gear 204 to rotate clockwise, and the second gear 204 and the first gear 201 Engagement, the second gear 204 rotating clockwise will drive the first gear 201 to rotate counterclockwise. In addition, the second gear is connected to the second rod, and the first gear is connected to the first rod, so the second gear drives the second rod to move. The first gear drives the first rod to move. The first bar that moves drives the pull bar of the first lock body to move, and because the pull bar is connected with the dead bolt, the dead bolt moves to disengage the dead bolt from the lock hole of the first lock seat.
