     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0022]    While certain exemplary embodiments have been described and shown in the accompanying drawings, it is to be understood that such embodiments are merely illustrative of and not restrictive on the broad invention, and that this invention is not be limited to the specific constructions and arrangements shown and described, since various other modifications may occur to those ordinarily skilled in the art. 
         [0023]    Please refer to  FIG. 2A , a composite structure  2  includes a first board  21  and a second board  22 . The first board  21  contains two male fitting  23  fixed firmly. The second board  22  contains a first side  221  and a second side  222 , and both the first side  221  and second side  222  have two grooves  223  thereon. Each groove  223  has a wedge  24  disposed therein. In this embodiment, the first board  21  and the second board  22  is made of wood, however, they may be replaced with metal or plastic. 
         [0024]    Moreover, the male fitting  23  includes a fitting head  231 , a locking pin  232 , a fitting base  233  and a male thread  234 . And, both the radius of the fitting head  231  and of the fitting base  233  are larger than the radius of the locking pin  232 . Besides, the wedge  24  has a fork  242  disposed at the front of the wedge  24  and a mounting  241  disposed at the rear of the wedge  24 . Wherein, the fork  242  is extended from the mounting  241 . The fork  242  has a slot  243  with width smaller than the radius of the fitting head  231 . In addition, the fitting base  233  is abutted against the surface of the first board  21  and the male thread  234  is locked beneath the surface of the first board  21 . 
         [0025]    When the first board  21  and the second board  22  are to fabricate, only to align the groove  223  with the male fitting  23  and then move the second board  22  downward so as to drive the male fitting  23  to enter the groove  223 . Afterward, please refer to  FIG. 2B , push the second board  22  toward the right in order to urge the locking pin  232  (refer to  FIG. 2A  simultaneously) to enter the slot  243  of the wedge  24 . Since the thickness of the fitting head  231  is approximating to or slightly larger than the distance from the fork  242  to the groove base  2231 , the fitting head  231 , as the result, is clipped by the fork  242  and the groove base  2231 . Thus the second board  22  may be fixed firmly on the first board  21 . Furthermore, due to the friction between the fitting head  231  and the fork  242  or the groove base  2231 , there must be a larger enough force to push the first board  21  leftward and overcome the friction; if so, the fork  242  may be departed from the fitting head  231  and then the first board  21  may be departed from the second board  22 . In this case, when the male fitting  23  is coupled to the wedge  24 , the fork  242  and the locking pin  232  are tight fit so as to reinforce the combination between the male fitting  23  and the wedge  24 . 
         [0026]    In aforementioned description, we may understand the reliability and simplification of the composite structure  2  of present invention. When fabricating the first board  21  and the second board  22 , it is only to align the groove  223  with the male fitting  23  so as to make the male fitting  23  locate inside the groove  223 , then pushing a horizontal force on the second board  22  to make the male fitting  23  and the wedge  24  be fastened. In the meantime, the fitting head  231  is clipped by the fork  242  and the groove base  2231 , and as a result the second board  22  is coupled to the first board  21 . 
         [0027]    Next, a cabinet will be introduced to show how present invention works and what benefit it may have. Please refer to  FIG. 3 ,  FIG. 3  is an application diagram of cabinet in present invention. As shown in  FIG. 3 , the upside of a cabinet  3  includes three shelves  31 , two side panels  32  and a back panel  34  thereof. The side panels  32  contain pluralities of male fittings  23 ; the shelves  31  and the back panels  34  contain pluralities of grooves  223 . Each groove  223  comprises a wedge  24  as shown in  FIG. 2A . In  FIG. 3 , the side panel  32  is corresponded to the first panel  21  in  FIG. 2A , and the shelf  31  is corresponded to the second board  22  in  FIG. 2A . When fabricating the side panel  32  and the shelf  31 , it is only to align the groove  223  with the male fitting  23  so as to make the male fitting  23  locate inside the groove  223 , then pushing a horizontal force on the side panel  32  to make the side panel  32  couple to the shelf  31 . Additionally, the fabricating procedure of the back panel  34  is similar to those of previous description, thus no need for further addressing. 
         [0028]    To compare the present invention with screw locking of prior art in  FIG. 1 , the fabricating time of present invention is obviously reduced. Furthermore, the side panel  32 , shelf  31  and the back panel  34  are fabricated without any screw, thus the cabinet  3  may be capable of multi times of fabrication or disassembling without loosing its components. 
         [0029]    Except that, there is still another configuration. Please refer to  FIG. 4 ,  FIG. 4  is schematic diagram for coupling of male fitting and female fitting. As shown in  FIG. 4 , the first board  21  includes a male fitting  23  and a female fitting  25  disposed at the upside and the underside of the first board  21  respectively. The male fitting  23  and the female fitting  25  have similar configuration; however, the female fitting  25  has a female thread  254  to match up with and fasten the male thread  234  so as to couple the male fitting  23  and the female fitting  25 . Afterward, please refer to  FIG. 5 ,  FIG. 5  is schematic diagram of composite structure in second embodiment of present invention. As shown in  FIG. 5 , due to the disposition of the male fitting  23  and the female fitting  25 , the first board  21  is able to couple the second boards  22  at the upside and the underside of the first board  21  respectively. In this case, the male fitting  23  and the female fitting  25  are coupled by means of fastening the male thread  234  and the female thread  254 . 
         [0030]    In practice, each lateral of the second board  22  may dispose more than two grooves  223  in the first side  221  or in the second side  222  which are depicted in  FIG. 5 , according the span width of the first board  21  and the second board  22 ; i.e., there is no restriction placed on the number of the groove  223 . Correspondingly, the male fitting  23  and the female fitting  25  on the first board  21  are definitely disposed according the number of the grooves  223 . 
         [0031]    Besides, those skilled in the art may embed the fitting base  233  of the male fitting  23  into the first board  21 , i.e., dispose the fitting base  233  inside the first board  21 , instead of abutting against the surface of the first board  21  shown in  FIG. 2A , in order to reduce the volume of the fitting base  233  exposing outside. Even more, the fitting base  233  may be neglected. 
         [0032]    Additionally, compare to the mounting  241  fastening by three screws  2411  shown in  FIG. 2A , the screw  2411  may also change its number with one or two screws  2411 . As for the configuration of the male fitting  23 , the circle-shaped fitting head  231  may be replaced. Please refer to  FIG. 6A , the fitting head  231 ′ and the fitting base  233 ′ of the male fitting  23 ′ are hexagon; the hex head  231   a ′ is specifically for hex wrench. In  FIG. 6B , the fitting head  231 ″ of the male fitting  23 ″ is cone-shape; the Philips head  231   a ″ is specifically for screwdriver. Moreover, the female fitting  25  may have similar configuration like fitting head  231 ′ and fitting base  233 ′ in male fitting  23 ′, or fitting head  231 ″ and fitting base  233 ″ in male fitting  23 ″. 
         [0033]    In aforementioned embodiments, the material of the male fitting or the female fitting may be metal, plastic or other materials. Besides, the fitting base  233  in  FIG. 2A  may be designed with other configuration. Please refer to  FIG. 7 ,  FIG. 7  is schematic diagram of male fitting of further embodiment. The male fitting  43  contains a fitting head  431 , a locking pin  432  and a fitting base  433 . In this embodiment, the male fitting  43  has no male thread  234  as shown in  FIG. 2A . Instead, the male fitting  43  has the fitting base  433  with cubic shape, and the fitting base  433  has two screw holes  4331  disposed at two ends of the fitting base  433  respectively. And then the male fitting  43  is able to be firmly fixed on the first board  21  by the screw holes  4331 . 
         [0034]    Thus, while the present invention has been described with reference to specific examples, which are intended to be illustrative only and not to be limiting of the invention, it will be apparent to those of ordinary skill in the art that changes, additions or deletions may be made to the disclosed embodiments without departing from the spirit and scope of the invention.
