Description

Technical Field

[0001] The utility model relates to the technical field of barcode scanning guns, in particular to a barcode scanning gun group structure. Background Art

[0002] QR codes or barcodes have been widely used in logistics information systems as a timely, accurate, reliable and economical means of data input. QR codes or barcodes are used to identify the identity information of different goods and packages. As a QR code or barcode recognition tool, barcode scanners play an important role in the logistics industry, especially the express delivery industry.

[0003] In addition, the barcode scanner gun bracket used in conjunction with the barcode scanner gun plays the role of supporting the barcode scanner gun. The function of the barcode scanner gun bracket in the prior art is relatively single. When in use, it is necessary to scan a variety of goods. Because the sizes of the goods are different, it is necessary to adjust the position, angle and other parameters of the barcode scanner gun in time to increase its applicability.

[0004] Therefore, whether it is possible to design a device for use with a barcode scanner that is easy to operate and has a wide range of usage scenarios is the problem that this patent wants to solve.
