[0058] The working principle of the present invention is as follows: the bracket is mainly suitable for the installation and support operation of the code reader 11.

The single-chip microcomputer 17 can quickly and intelligently adjust the spatial code reading position and code reading angle of the code reader 11 through the positioning recognition result of the positioning camera 10, which is conducive to accurate code reading operations. The single-chip microcomputer 17 finally uses the data feedback of the ranging probe 16 to keep a constant code reading distance between the positioning camera 10 and the code body. After the code reading distance is maintained, the indexing frame 7 drives the code cleaning nozzle 42 to face the code body, and uses high-pressure airflow to perform preliminary air cleaning on the two-dimensional code on the surface of the object to be scanned. After the air cleaning is completed, the indexing frame 7 drives the code reader 11 to rotate to above the two-dimensional code on the surface of the object to be scanned, thereby realizing fast and accurate code reading operations.
