As shown in fig. 5 and 6, the upper case 30 is U-shaped, a blocking piece 35 for blocking the first spring 81 and a fixing post 34 for fixing the second spring 83 are disposed inside the upper case 30, one end of the first spring 81 abuts against the blocking piece of the upper case 30, and the other end of the spring 81 abuts against the latch pushing plate 90; the second spring 82 is fitted over the fixing post of the upper case 30. The fingerprint module circuit board 60, the key push plate 62, the power supply 63, the fixing plate 70, the latch push plate 80, the main control circuit board 90 and the motor 91 are all fixed between the upper case 30 and the lower case 20.

The upper surface of the upper case 30 is provided with an upper case upper opening 31, and the fingerprint window pushing plate 50 is fixed in the upper case 30 and the fingerprint window pushing plate 50 is exposed from the upper case upper opening 31. The side of the upper shell 30 is provided with an upper shell side opening 32.

The cleat assembly 40 includes a pin hole 41 extending into the upper housing 30, and the pin hole 41 extends into the upper housing 30 through the upper housing side opening 32 of the upper housing 30. As shown in fig. 12, the latch push plate 80 is provided with a push plate groove 801 and a latch 802 which are oppositely arranged, respectively. The first spring 81 is located in the pusher recess 801 and the surface of the latch 802 is beveled in the direction of entry of the blade assembly 40 when the lock is closed. The latch hole 41 is extended into the upper case 30 through the upper case side opening 32 of the upper case 30, and the latch 802 is inserted into the latch hole 41 by the elastic force of the first spring 81. When the lock is unlocked, the buckle piece device 40 is directly pushed manually, and the bolt 802 falls off the bolt hole 41, so that the lock is safer and more reliable.
