The height adjustment component 3 is connected to the mounting base 13.
[0026] The height adjustment assembly 3 includes a driving wheel 31, a driven wheel 32, a lifting adjustment rod 33, a mounting seat 34 and a driving motor (not shown in the figure). The mounting seat 34 and the driving motor are both mounted on the upper surface of the mounting base 13. The driving wheel 31 is mounted on the output shaft of the driving motor. The driven wheel 32 is rotatably connected to the mounting seat 34 through a rotating shaft. The driven wheel 32 and the driving wheel 31 are mutually meshing gears, and the number of teeth of the driven wheel 32 is greater than the number of teeth of the driving wheel 31. The lifting adjustment rod 33 is fixed to the side of the driven wheel 32 away from the mounting seat 34. The lifting adjustment rod 33 extends outward along the radial direction of the rotating shaft of the driven wheel 32, and the end portion exceeds the outer contour of the driven wheel 32. The angle adjustment assembly 4 is mounted on the free end of the lifting adjustment rod 33 that exceeds the outer contour of the driven wheel 32. The driving motor can drive the driving wheel 31 to rotate, and the driven wheel 32 and the lifting adjustment rod 33 can be rotated through the meshing relationship, thereby adjusting the height of the reader 2 on the lifting adjustment rod 33.
