     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0021]     The following descriptions are of exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.  
         [0022]     Referring to  FIGS. 1 and 2 , the main body of the tray in accordance with the present invention comprises a hood  1 , an upper sliding mount  2 , a main frame  3  and a plurality of plates  4 . As shown in  FIG. 1 , it is a preferred configuration of the tray in accordance with the present invention. The hood  1  is connected to the sliding mount  2  and the blocking plate  11  at the hood  1  is used an urging function when the sliding mount  2  is depressed. The hood  1  can be mounted with lighting device.  
         [0023]     As shown in  FIG. 2 , the upper sliding mount  2  is a hollow frame structure having a top end connected to the hood  1  so that the entire sliding mount  2  is positioned within the hollow body of the main frame  3 . There are magnetic components  21 ,  31  on the sliding mount  2  and the main frame  3  and are attracted to each other. The top portion of the sliding mount  2  is provided with sufficient distance to allow movement. The upper section of the sliding mount  2  and the main frame  3  are attracted by way of magnetic components  21 ,  31  at corresponding positions. When the sliding mount  2  is inserted into the hollow body of the main frame  3 , it is positioned by the attraction force of the magnet components. When the sliding mount  2  is depressed, the magnetic component  21  will not move away from the main frame  3 , as shown in  FIG. 4 . Thus there are corresponding magnetic component  22  positioned at the plate  4  and the middle section of the plate  4  is provided with a magnetic component  41  to repel magnetic component  23 , as shown in  FIG. 3 .  
         [0024]     As shown in  FIG. 2 , the number of plates depends on the shape of the main frame  3 , for instance  FIG. 8  (triangular) and  FIG. 9  (hexagonal). The plate  4  and the main frame  3  are attached together. The plate  4  can be either in extended form or in a closing form When the sliding mount  2  is depressed to move, the magnetic component  22  will move and repel the magnetic component  23  so that the plate  4  is pushed away, as shown in  FIG. 7 .  
         [0025]     Each plate  4  is provided with notch  42  when it is extended, and the top and middle position of the plate  4  is a lining arm  43  which is pivotally connected to the main frame  3  such that the plate  4  is extended about the linking arm  43 .  
         [0026]     As shown in  FIG. 2 , the main frame  3  has a rotating disc  30  at the bottom of the frame  3  and is also provided with magnetic component  31 . The main frame  3  is provided with railing slot  32  corresponding to the linking arm  43  for the storage of the linking arm  43 . Each corner of the main frame  3  is provided with rows of notches  33  which is in horizontal position with that of the notches  42  of the plate, as shown in  FIGS. 6 and 7 .  
         [0027]     It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above.  
         [0028]     While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.
