BACKGROUND OF THE INVENTION  
       [0001]     1. Field of the Invention  
         [0002]     The present invention relates to a window shade and more particularly, to an easy-to-install window shade that is easy to install and easy to dismount.  
         [0003]     2. Description of the Related Art  
         [0004]      FIG. 1  shows a window shade according to the prior art. According to this design, the window shade comprises a headrail  2 , a shade body  1 , which has the top side thereof fixedly fastened to the headrail  2 , and two brackets  3  fixedly provided at the top side of the headrail  2  for fastening to the wall above the window. Because the brackets  3  are fixedly provided at the top side of the headrail  2 , it is inconvenient to affix the brackets  3  to the wall above the window. It is also inconvenient to remove the brackets  3  from the wall when wishing to wash the shade body  1  after a long use of the window shade. Further, the user must carefully affix the brackets  3  to the wall above the window. Improper installation of the brackets  3  in the wall above the window may cause the shade body  1  unable to shade the whole area of the window. After installation, it does not allow the user to adjust the elevation of the shade body.  
         [0005]     Therefore, it is desirable to provide a window shade that eliminates the aforesaid drawbacks.
