The rear end of the first fixing base 16 is welded to the inner side of the moving plate 17. The front end of the moving plate 17 is glued to the rear end of the rubber block 25.

[0027] During operation, the first fixed block 14 moves, driving the first fixed rod 15 inside the first fixed base 16 to rotate along the inside of the first fixed block 14 and flip outward, driving the front end of the movable plate 17 to flip outward, and at the same time, the rubber block 25 at the front end of the movable plate 17 will open outward, thereby driving the bent or warped barcode or QR code to be stretched and flattened, which is used to flatten and stretch the bent or warped barcode or QR code.

[0028] Furthermore, the bottom end of the groove 10 is welded to the bottom end of the guide rod 19 near the upper position of the motor 11, and the top end of the guide rod 19 is welded to the bottom end of the limit block 20, and the guide rod 19 and the limit block 20 are both circular in design;

[0036] Working principle: When a barcode or QR code with a bent or warped edge needs to be flattened and stretched out during code scanning, first place the rubber block 25 at the front end of the device body 1 against the two ends of the barcode or QR code, and then start the motor 11 inside the groove 10 to drive the threaded rod 12 to rotate. When the threaded rod 12 rotates, the sleeve rod 13 is driven to move outward along the surface of the threaded rod 12, and the first fixed block 14 is driven to move. At the same time, when the sleeve rod 13 moves, the moving block 18 is driven to move along the surface of the guide rod 19, and the limit block 20 at the top of the guide rod 19 can play a limiting role to prevent the moving block 18 from falling off. The first fixing block 14 moves away from the surface of the guide rod 19, and when the first fixing block 14 moves, the first fixing rod 15 inside the first fixing base 16 is driven to rotate along the inside of the first fixing block 14 and flip outward, driving the front end of the moving plate 17 to flip outward, and at the same time, the rubber block 25 at the front end of the moving plate 17 will open outward, thereby driving the bent or warped barcode or QR code to be stretched and flattened, and when the front end of the moving plate 17 opens outward, it drives the rotating block 23 to rotate and open along the surface of the second fixing rod 22 inside the second fixing base 21, so as to flatten and stretch the bent or warped barcode or QR code.

[0037] When the code scanning device body is to be placed and fixed, the bottom of the device body 1 is pressed against the desktop, driving the suction cup 24 at the bottom of the device body 1 to be adsorbed above the desktop, thereby increasing the stability of the device body 1 and being used to place and fix the code scanning device body.
