   DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
   Please refer to  FIGS. 1 ,  2  and  3 . A housing  1  according to the present invention comprises two half-housings  10  and  20 . As  FIG. 2  shows, the half-housing  10  has a bottom plate  11  therein combined with a front plate  12  and side plate  13 . The half-housing  20  has a bottom plate  21  combined with a front plate  22 , side plate  23  and back plate  24 . Two base plates of two detachable pivot elements  30  are connected respectively to the two bottom plates  11  and  21 . Whereby, the two bottom plates  11  and  21  can be expanded to form a plane state, or can be assemble to form a vertical state as  FIG. 1  shows, or can be detached to form a detachment state as  FIG. 3  shows. 
   The front plates  12  and  22  have groove holes  121 ,  122  and  221  respectively for receiving electronic elements such as CD-ROM driver and disk driver respectively. The groove holes  121  and  122  have groove walls  123  and  124  in them respectively so as to form a space for receiving the electronic element. 
   As  FIG. 1  shows, one side at the upper side of the side plate  13  is combined with a buckling unit  40 . The buckling  40  has three groove holes  41 ,  42  and  43  therein receiving respectively three projecting columns  131 ,  132  and  133 . The three projecting columns  131 ,  132  and  133  are combined at the upper side of the side plate  13  and have respectively cap portions with bigger outer diameter at the upper sides of them, the cap portions are passed through the holes with a bigger diameter at sides of the three groove holes  41 ,  42  and  43  and stuck at the outer sides of the holes with a smaller diameter, so as to allow the buckling unit  40  not to separate from the side plate  13 , but can allow the three groove holes  41 ,  42  and  43  to move to and fro along the flank sides of the projecting columns  131 ,  132  and  133 . An elastic unit  50 , such as a twisting spring, is connected between the buckling unit  40  and the side plate  13  so as to cause the buckling unit  40  always to bear a spring force that the elastic unit  50  pushes it toward a flank side. The buckling  40  has two buckling ends  44  and  45  therein that are extended downward out of the groove holes  134  and  135  at the flank side of the side plate  13  to the outside of them, as  FIG. 2  shows. Two ear sheets  231  and  232  can be combined at the places inside the flank side of the side plate  23  corresponding to the two buckling ends  44  and  45 . The ear sheets  231  and  232  can be buckled in the two buckling ends  44  and  45 . 
   When the two half-housings  10  and  20  is formed as an assemblage state shown in  FIG. 1 , the two buckling ends  44  and  45  of the buckling unit  40  are buckled respectively with the two ear sheets  231  and  232  so as to cause the two side plates  13  and  23  to be buckled together. The two side plates  13  and  23  cannot be separated unless an outer force is exerted to cause the buckling unit  40  to squeeze the elastic element  50  to move toward another side to allow the two buckling ends  44  and  45  to separate from the place that the two buckling ends  44  and  45  are buckled with the two ear sheets  231  and  232 . 
   Please refer to  FIGS. 4 and 5 , a detachable pivoting element  30  comprises a seat body  31  with a long hole  310  connected with a sliding shaft  311 . The front end of a mobile sheet  32  is pivoted to the sliding shaft  311 . The front end of a base plate  33  is connected to a rotating shaft  331 . the rear end of the seat body  31  is pivoted to the rotating shaft  331 . 
   The mobile sheet  32  is pivoted to two rear parts  341  of a mobile frame  34  behind a place that it is pivoted with the sliding shaft  311 . The front end of the seat body  31  has a guiding groove  312 . A front shaft  342  of the mobile frame  34  is received in the guiding groove  312 . When the mobile sheet  32  is raised upward, the two rear end parts  341  of the mobile frame  34  can be driven to move forward so as to cause the front shaft  342  to move forward in the guiding groove  312 . 
   Another base plate  35  has a buckling part  351  that projects upward and operates coordination with the seat body  31 . Grooves  352  and  353  are disposed respectively at the places that the front and rear ends of the buckling part  351  corresponding to the front shaft  342  and sliding shaft  311 . The base plates  33  and  35  have multiple of holes  332  and  354  to combine fixing elements to fix on the base plates  21  and  11  respectively as  FIG. 3  shows. 
   A buckling sheet  36  is buckled at the front end of the seat body  31  to seal the front end of the guiding groove  312  so as to allow the front shaft  342  not to separate from the guiding groove  312 . 
   When the front shaft  342  and sliding shaft  311  of the detachable pivot unit  30  are buckled respectively in the grooves  352  and  353  at the front and rear ends of the buckling part  351 , the seat  31  and the buckling part  351  form a connection state, and so are the two base plates  33  and  35 . The two base plates  33  and  35  as well as the two base plates  11  and  12  are allowed to form a 180° expansion or 90° closing-up assemblage state as  FIGS. 1 and 2  shows, because the seat body  31  and the base plate  33  are pivoted together by use of the rotating shaft  331 . At this time, the two rear end parts  341  of the mobile frame  34  are located at a place below the front shaft  342  and the sliding shaft  311 . The rear end part  341 , the front shaft  342  and the sliding shaft  311  form a triangle pattern. The mobile sheet  32  can be kept at a stable state, because the two rear end parts  341  hold up its rear end. The front shaft  342  cannot be driven to move forward unless an outer force is exerted to raise the rear end of the mobile sheet  32  upward to cause the two rear end parts  341  to surpass the line connected between the front shaft  342  and the sliding shaft  311 . 
   When a user raises the mobile sheet  32  upward and the front shaft  342  of the mobile sheet  34  to move forward along the guiding groove  312 , the front shaft  342  can be separated from the groove  352  at the front end of the buckling part  351 , And then, move the front shaft  342  upward and backward to retreat to a back shrinking section  355  at one side of the groove  352  to cause the sliding shaft  311  to move backward along the long hole  310  to separate from the groove  353  at the rear end of the buckling part  351  so as to separate the seat body  31  and the buckling part  351 ; this can separate the two base plates  33  and  35  as well as the two bottom  11  and  21  shown in  FIG. 2 . 
   The two half-housings form a separation state according to the present invention, this can allow the operation space while assembling is bigger than the operation space while the two half-housings expanding so that every electronic element assemblage and maintenance are more convenient and the density of electronic parts in the assemblage space can be raised. Furthermore, the assemblages of electronic parts can be separated at different companies or locations according to the needs, and then, combine the two half-housings. Whereby, the assemblage operation can be various and more convenient. 
   The characteristic of the present invention is allowing two half-housings to form an expansible and detachable structure. Using a detachable pivoting element can allow two bottom plates of a housing to be combined to be perpendicular to each other, to be expanded to be level or to be detached. Using a buckling unit can allow the combination and expansion of the two half-housings to be more convenient. The housing according to the present invention can have various different combination types. And further can satisfy a manufacturer or user with different needs. 
   The description mentioned above is to take the housing of a personal computer as an example to describe, but to the person skilled in the art can easily apply it to housings of the other electronic products according to the present invention. 
   It is noted that the expansible and detachable housing of a electronic device described above is the preferred embodiment of the present invention for the purpose of illustration only, and are not intended as a definition of the limits and scope of the invention disclosed. Any modifications and variations that maybe apparent to a person skilled in the art are intended to be included within the scope of the present invention.
