[0056] In the first state, the upper cover 2 faces the direction inside the house, and at the same time, the inclined surface side of the oblique tongue 102 faces the direction inside the house. The second limiting rod 14 is removed from the upper connecting rod 5. When the handle located outside the door rotates, it drives the lower toggle 12 to rotate idly, so that unlocking cannot be performed through the handle outside the door. When the handle located inside the door rotates, the upper toggle 11 drives the upper connecting rod 5 to rotate through the first limiting rod 13.
[0057] In the second state, the upper cover 2 faces the direction outside the house, and at the same time, the oblique tongue 102 is rotated so that the inclined surface side of the oblique tongue 102 faces the direction inside the house. The first limiting rod 13 is removed from the upper connecting rod 5. When the handle located outside the door rotates, it drives the upper toggle 11 to rotate idly, so that unlocking cannot be performed using the handle outside the door. When the handle located inside the door rotates, the lower toggle 12 drives the upper connecting rod 5 to rotate through the second limiting rod 14.

A motor 17 for pushing the clutch block 15 to rotate so that it forms a snap-fit with the upper toggle 11 and the lower toggle 12 is also provided inside the lock case 1. When the clutch block 15 forms a snap-fit with the upper toggle 11 and the lower toggle 12, rotating the handle located outside the door causes the upper toggle 11 or the lower toggle 12 to drive the upper connecting rod 5 to rotate through the clutch block 15.
[0059] A first engaging groove 1103 for snap-fitting with the clutch block 15 is formed on the upper toggle 11, and a second engaging groove 1202 for snap-fitting with the clutch block 15 is formed on the lower toggle 12.
[0060] Further, a toggle block 1701 is provided on the output end of the motor 17. The motor 17 drives the toggle block 1701 to move to push the clutch block 15 to rotate, so that the clutch block 15 forms a snap-fit with the upper toggle 11 and the lower toggle 12.
[0061] Both the first limiting rod 13 and the second limiting rod 14 are screws. The structure of the screws is convenient for disassembly. Two through holes 202 are formed on the upper cover 2, and the two through holes 202 correspond to the positions of the first limiting rod 13 and the second limiting rod 14 respectively. In this way, the first limiting rod 13 and the second limiting rod 14 can be disassembled and assembled without removing the upper cover 2.
[0062] Such asFigure 3 and 5 As shown, at this time, the lock body is in a locked state, and the inclined bolt 102 and the main lock plate 103 both extend out of the panel 101.
[0063] like Figure 3 As shown in the figure, the lock body is in the state when the second limit rod 14 is removed. At this time, the upper cover 2 of the lock body faces the direction of the house, and the inclined side of the inclined tongue 102 faces the direction of the house. When unlocking, the handle outside the door is turned, and the handle outside the door drives the lower paddle 12 to rotate idly, and the handle outside the door cannot open the door. When the lock is successfully unlocked using a password or fingerprint on the lock body, the motor 17 drives the paddle block 1701 to move to push the clutch block 15 to rotate, and the clutch block 15 forms a card with the lower paddle 12. Then, when the handle outside the door is turned again, the lower paddle 12 can push the upper connecting rod 5 to rotate. After the upper connecting rod 5 rotates, the first paddle portion 501 drives the inclined tongue 102 to move so that the inclined tongue 102 retracts into the lock housing 1. The upper connecting rod 5 drives the upper slide plate 7 to rotate through the upper push rod 8. The upper slide plate 7 drives the lower slide plate 9 to rotate by pushing the first bending portion 901. After the lower slide plate 9 rotates, it drives the main lock plate 103 to retract into the lock housing 1 through the first bending portion 901, and the unlocking is completed. Figure 4 shown.
[0064] When opening the door inside the house, the handle inside the door is rotated, and the handle inside the door drives the upper paddle 11 to rotate, and the upper paddle 11 drives the upper connecting rod 5 to rotate by pushing the first limiting rod 13.
[0065] like Figure 5 As shown in the figure, the lock body is in the state when the second limit rod 14 is removed. At this time, the upper cover 2 of the lock body faces the outside of the house, and the inclined tongue 102 is rotated so that the inclined side of the inclined tongue 102 faces the inside of the house. When unlocking, the handle outside the door is rotated, and the handle outside the door drives the upper paddle 11 to rotate idly, and the handle outside the door cannot open the door. When the lock is successfully unlocked using a password or fingerprint on the lock body, the motor 17 drives the paddle block 1701 to move to push the clutch block 15 to rotate, and the clutch block 15 and the upper paddle 11 are engaged. The upper connecting rod 5 is rotated, and the first toggle portion 501 drives the inclined tongue 102 to move so that the inclined tongue 102 is retracted into the lock housing 1. The upper connecting rod 5 drives the upper slide plate 7 to rotate through the upper push rod 8. The upper slide plate 7 drives the lower slide plate 9 to rotate by pushing the first bending portion 901. After the lower slide plate 9 rotates, it drives the main lock plate 103 to retract into the lock housing 1 through the first bending portion 901, and the unlocking is completed. Figure 6 shown.
[0066] When the door is opened inside the house, the handle inside the door is rotated, and the handle inside the door drives the lower paddle 12 to rotate, and the lower paddle 12 drives the upper connecting rod 5 to rotate by pushing the second limiting rod 14.
