[0002] The QR code scanning and traceability technology is to scan the QR code of the product to query the information of each link such as production, circulation, sales and consumption of the product, so as to trace the source and destination of the product, so that users can judge the authenticity and quality of the product from the information obtained by scanning the code. Before the product enters the market in batches, it is necessary to scan the code to trace its source, and a scanner is required for product traceability scanning.

[0003] In the prior art, an authorized patent with announcement number CN219574812U discloses a product traceability scanner, including a transmission belt, a support frame fixedly connected to the outside of the transmission belt, two fixed plates fixedly connected to the top of the support frame and symmetrically distributed, the two fixed plates are slidably connected to the same movable plate on opposite sides, the fixed plate on the right side is internally rotatably connected to a first screw, and the first screw is fixedly connected to the outside of the first screw. The product traceability scanner has the advantages of easy adjustment, etc., which solves the problem that the manual handheld scanner requires more labor costs and has low scanning efficiency; although the method of fixing the scanner on a non-adjustable bracket is more convenient than the manual scanning method, the product change speed is fast, and the positions and sizes of the QR codes of different products are different, so it is necessary to adjust the position of the scanner to adapt to the problem of scanning different types of product QR codes.

[0004] However, the above technical solution still has the following shortcomings in actual use: due to the fast product changeover speed, the operation method of adjusting the height of the barcode scanner by shaking the first screw rod with a joystick and adjusting the horizontal position of the barcode scanner by driving the second screw rod with a motor has the problems of slow adjustment speed and inconvenient operation, thereby reducing the overall scanning efficiency. In this regard, we propose a barcode scanner that is easy to operate. Utility Model Content
