[0031] The positioning block 4 is movably engaged with the first positioning groove 6, and a slide groove 7 is connected between the first positioning grooves 6. A clamping block 8 is movably engaged with each of the two ends of the slide groove 7. A clamping groove 5 is opened on the side of the positioning block 4 close to each other, and the clamping block 8 is movably engaged with the clamping groove 5. Two second positioning grooves 3 are opened on the side of the device body 1 away from the first positioning groove 6;

[0032] A stopper 12 movably fitted between the blocks 8;

[0033] The stopper 12 is movably engaged in the device body 1, and a first cipher disk 18 is provided on the upper side of the end of the stopper 12 away from the card block 8. The first cipher disk 18 is rotatably connected to the device body 1 through a bearing, and a second cipher disk 20 is provided below the first cipher disk 18. The second cipher disk 20 is rotatably connected to the device body 1 through a bearing. A fixing groove 16 is opened near the top of the stopper 12 of the device body 1, and a shifting block 17 is movably engaged in the fixing groove 16. The shifting block 17 is welded with the stopper 12. The device body 1 is a U disk body. The card block 8 engages with the card slot 5 to fix the positioning block 4 in the first positioning groove 6, thereby fixing the protective cover 2. The positioning block 4 can be embedded in the second positioning groove 3. The stopper 12 can slide in the device body 1. When the stopper 12 is blocked between the card blocks 8, the card blocks 8 will be fixed and cannot be moved. Both the first cipher disk 18 and the second cipher disk 20 can rotate in the device body 1, and at the same time, scales are provided on the surfaces away from each other. The shifting block 17 can drive the stopper 12 to move along the fixing groove 16.

[0034] Specifically, a second limiting block 14 is welded on the top of the clamping block 8 , a second limiting groove 13 is opened on one side of the device body 1 close to the second limiting block 14 , and the second limiting block 14 is movably engaged with the second limiting groove 13 .

[0035] Through the above technical solution, the second limiting block 14 can move in the second limiting groove 13, and the second limiting block 14 can drive the clamping block 8 to move.

[0036] Specifically, a second elastic member 15 is engaged between the second limiting blocks 14 , and the second elastic member 15 is movably fitted in the second limiting groove 13 .

[0037] Through the above technical solution, the second elastic member 15 can push the two second limiting blocks 14 to separate by its own elastic force.

[0038] Specifically, first limiting grooves 9 are formed on both sides of the device body 1 close to the stopper 12 , and the first limiting blocks 10 are movably engaged in the first limiting grooves 9 , and the first limiting blocks 10 are welded to the stopper 12 .

[0039] Through the above technical solution, the first limiting block 10 can move in the first limiting groove 9, and the first limiting block 10 can drive the stopper 12 to move.

[0040] Specifically, a first elastic member 11 is provided on a side of the first limiting block 10 away from the clamping block 8 , and the first elastic member 11 is movably fitted in the first limiting groove 9 .

[0041] Through the above technical solution, the first elastic member 11 can push the first limiting blocks 10 to separate from each other through its own elastic force.

[0042] Specifically, a first password slot 19 is formed on one side of the first password disk 18 close to the stopper 12 , and the stopper 12 is movably embedded in the first password slot 19 .

[0043] Through the above technical solution, the stopper 12 can pass through the first password slot 19 .

[0044] Specifically, a second password slot 21 is formed on one side of the second password disk 20 close to the stopper 12 , and the stopper 12 is movably embedded in the second password slot 21 .

[0045] Through the above technical solution, the block 12 can pass through the second password slot 21. Only when the first password slot 19 and the second password slot 21 are aligned with the block 12 at the same time, can the block 12 move in the device body 1, so that it is no longer blocked between the card blocks 8. At this time, half of the block 12 is embedded in the first password slot 19 and the second password slot 21 respectively.

[0046] When in use, during daily wear, the card block 8 can be embedded in the card slot 5 to fix the positioning block 4 in the first positioning slot 6, thereby preventing the protective cover 2 from falling off, improving the portability of the device, and reducing the possibility of losing the protective cover 2. On this basis, when the device body 1 stores information that needs to be encrypted, the first password disk 18 and the second password disk 20 can be rotated so that the first password slot 19 and the second password slot 21 are not aligned with the block 12 at the same time, so that the block 12 cannot move without knowing the password, thereby blocking the two The card block 8 is immovable, and the protective cover 2 cannot be removed at this time to prevent data theft. When it needs to be opened, rotate the first password disk 18 and the second password disk 20 so that the first password slot 19 and the second password slot 21 are aligned with the block 12 at the same time. At this time, pull the dial block 17 by manpower, and the dial block 17 drives the block 12 to pass through the first password slot 19 and the second password slot 21, so that the two card blocks 8 are no longer blocked. Then pull the protective cover 2, and the card slot 5 will push the card blocks 8 closer to each other until the card block 8 is no longer embedded in the card slot 5. At this time, the protective cover 2 can be removed.
