One end of the two guide rods passes through the mounting frame 51. The mounting frame 51 is respectively slidably connected to the outer surfaces of the two guide rods, so as to limit the mounting frame 51 to move up and down only on the outer surfaces of the guide rods. Two rectangular blocks 54 are slidably installed inside the mounting frame 51, and a positioning fixture 55 for fixing the barcode reader is arranged on the opposite side of the two rectangular blocks 54.
