[0051] The working principle is that: combined with the above descriptionFigure 1 and Figure 2 The diagram shows the lock body structure before locking. Rotating the lock cylinder 7 causes its dial to rotate in the direction of arrow b. The dial touches the second contact head 51 of the latch drive linkage 5, causing the latch drive linkage 5 to move in the direction of arrow c. Simultaneously, the bottom of the second elongated groove 54 pushes against the second pin 65 of the linkage turntable 6, causing the linkage turntable 6 to rotate in the direction of arrow d and drive the latch to extend out of the side plate 12 of the housing in the direction of arrow e, thus achieving locking (at this time, the first pin 64 of the linkage turntable 6 rotates to the bottom of the first elongated groove 42 of the tongue unlocking linkage 4). The locked state is shown in the diagram. Figure 3 and Figure 4 As shown, by rotating the lock cylinder 7, its dial rotates in the direction of arrow f. The dial touches the first contact head 41 of the latch unlocking linkage 4, causing the latch unlocking linkage 4 to move in the direction of arrow g, thereby driving the dial to rotate in the direction of arrow i, which in turn drives the latch 2 to retract. At the same time, the bottom of the first elongated groove 42 pushes the first pin 64 of the linkage turntable 6, causing the linkage turntable 6 to rotate in the direction of arrow h. The second pin 65 drives the latch drive linkage 5 to reset. Simultaneously, the linkage turntable 6 (or the linkage turntable 6 and the dial touch the clearance groove 34) drives the latch 3 and the slide plate 31 to move and retract in the direction of arrow j, thereby simultaneously unlocking the latch and the latch.

[0052] In addition, the slanted tongue 2 can be reversed, combined with Figure 1 As shown, lift the limiting block 14 in the direction of arrow K to release the obstruction of the guide slider 15. The guide slider 15 drives the tongue 2 and the slide rod at the inner end of the tongue 2 to extend along the direction of L until the tongue extends out of the housing. Rotate the tongue along the direction of arrow R to realize the reversal. After the reversal, pull the guide slider 15 in the opposite direction of L. The limiting block 14 is reset under the action of the block reset spring 141 and blocks the guide slider 15 again. The root of the tongue enters the housing again and can be used normally.
