ABSTRACT:
An adjustment mechanism includes a limiting unit formed with a first channel and a second channel lying along first and second planes, a lower clamping unit having a U structure and being received within the first channel, a bottom seat unit disposed below and supporting the lower clamping unit from underneath, an upper clamping unit having inverted U structure and being received within the second channel such that the lower and upper clamping units are located at two opposite sides of the limiting unit with the first and second planes crossing each other perpendicularly. A top cover unit is disposed above and connected to the upper clamping unit. Adjusting position of the lower clamping unit and the limiting unit along the first plane and the upper clamping unit and the limiting unit along the second plane results in changing an angular position of the cover unit relative to the bottom seat unit.
