       9 . The fastening device in accordance with  claim 2 , wherein each of the upright bars is integrally formed with the first rings and the first hooks by bending. 
   
   
       10 . The fastening device in accordance with  claim 1 , wherein the at least two transverse bars are combined with the upright bars detachably. 
   
   
       11 . The fastening device in accordance with  claim 1 , wherein each of the at least two transverse bars is provided with a plurality of second rings which are located between the second hooks of the two opposite ends of each of the at least two transverse bars. 
   
   
       12 . The fastening device in accordance with  claim 11 , wherein the second rings of each of the at least two transverse bars are equally spaced from each other between the second hooks of the two opposite ends of each of the at least two transverse bars. 
   
   
       13 . The fastening device in accordance with  claim 11 , wherein each of the second rings of each of the at least two transverse bars is disposed at an upright state. 
   
   
       14 . The fastening device in accordance with  claim 1 , wherein the second hook of each of the at least two transverse bars has a substantially R-shaped profile. 
   
   
       15 . The fastening device in accordance with  claim 11 , wherein each of the at least two transverse bars is integrally formed with the second rings and the second hooks by bending. 
   
   
       16 . The fastening device in accordance with  claim 1 , further comprising at least two clips detachably mounted on an upper one of the at least two transverse bars.
