Two-axis rotary adjustment device of barcode reader scanning head

A two-axis rotary adjustment device of a barcode reader scanning head for adjusting a direction of the barcode reader scanning head to read barcodes, the two-axis rotary adjustment device comprising:

• a base having a vertical bearing;
• a U-shaped frame having a transversal beam and two side arms protruding downward and connecting to the transversal beam, the transversal beam comprising a vertical shaft formed on a top portion of the transversal beam, and the vertical shaft pivotally connecting and clamping the vertical bearing of the base so that the U-shaped frame is able to horizontally rotate on the base, wherein the side arms comprise two horizontal bearings respectively extending inwardly and aligning with each other;
• and
• a scanning head frame for storing the barcode reader scanning head, a scanning surface of the barcode reader scanning head facing outwardly, the scanning head frame comprising two horizontal shafts outwardly locating at two sides of the scanning head frame and aligning with each other, the horizontal shafts pivotally connecting and clamping the horizontal bearings of the side arms respectively so that the scanning head frame is able to vertically rotate on the side arms.
