BACKGROUND  
         [0001]    1. Technical Field of the Invention  
           [0002]    The present invention provides a kind of joint apparatus for personal digital assistant (PDA) and multimedia module, which comprises a boxed structure, an interface card component, a fixture assembly and an elastic assembly.  
           [0003]    Since forcing the fixture assembly of joint apparatus outwardly and plugging the interface card of PDA interface equipment into the slot of PDA interface equipment. The elastic assembly will push the fixture assembly to connect with the joint apparatus to drive the bayonet lock and to interlock the PDA interface equipment, thus the function of multimedia module is able to affect on and install in PDA interface equipment obviously.  
           [0004]    2. Description of the Prior Art  
           [0005]    In utilizing of conventional interface card, since an interface card plugged into the slot of PDA interface equipment, as unlocking an interface card which would be pressed downwardly to make a release between the interface card and the slot, consequently the interface card is able to removed out. Contrarily, an outwardly compelling force to draw the interface card from the slot which will cause to the damage of the interface card or the impairment of the inner portion of the slot of PDA interface equipment.  
         SUMMARY OF THE INVENTION  
         [0006]    The present invention relates to an inner structure technique for the joint apparatus for personal digital assistant (PDA) and multimedia module in an assembling matter. The effect of multimedia module been will display on the PDA interface equipment immediately as well as the technique of the storage will be stored in the PDA.  
           [0007]    The further object of the present invention is a connection of the multimedia module and the PDA interface equipment to prevent this connection from falling apart.  
           [0008]    The foregoing object of said invention is to avoid forgetting to release the Inlay State into freedom and compelling from taking out the interface card. Such behavior will damage the interface card by the compelling force.

       DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0020]    Please refer to follow as FIGS.  1  to  6  shown as the present invention comprises a boxed structure ( 10 ), a PCB components assembly ( 20 ), an elastic assembly ( 30 ) and a fixture assembly ( 40 ).  
         [0021]    Please refer to FIGS. 1, 2 and  3  shown as the present invention, herein the boxed structure ( 10 ) comprises an upper lid ( 11 ), a bottom lid ( 12 ), and a board fence. The upper lid ( 11 ) is assembled onto the forward portion of the bottom lid ( 12 ) to protect the components that are mounted in its forward portion. The bottom lid ( 12 ) is main structure of the present invention, which can be assembled lots of components and structures. The bottom lid ( 12 ) includes several ribs ( 121 ) mounted on the rear portion, herein the positioned pillar ( 122 ) and elastic positioned slot ( 123 ) are mounted on both two lateral sides of the rear portion of the bottom lid ( 12 ). Additionally, an interlock ( 124 ) is opened at the rear end of the bottom lid ( 12 ). The board fence ( 13 ) is a flat board having an L-type-like stopper ( 131 ) at its one end, herein a plugging hole ( 132 ) is opened at the stopper ( 131 ), and the back side of board fence ( 13 ) with a positioned slot ( 133 ) and several ribs ( 134 ) mounted on.  
         [0022]    Please refer to FIG. 3 shown of present invention. The PCB components assembly ( 20 ), which comprises a PCB ( 21 ) and an interface card ( 22 ), primarily function as delivery information.  
         [0023]    Please refer to FIG. 4 shown of present invention, wherein the elastic assembly ( 30 ) is an S-type-like and flexible object, which the elastic extending portions ( 31 ) ( 32 ) stretching outwardly both former and rear ends.  
         [0024]    Please refer to FIG. 5 shown of present invention, wherein the fixture assembly ( 40 ) is a long board object, which the elastic extending portions ( 41 ) are stretched outwardly on both lateral sides of one end. Herein two chamfered portions ( 411 ) are opened towards the fixture assembly ( 40 ) on each extending portion ( 41 ). There are a pin hole ( 42 ), a bayonet lock ( 43 ), and a positioned block ( 44 ) on the other side of the fixture assembly ( 40 ).  
         [0025]    Please refer to FIG. 3 shown of present invention, the pins ( 221 ) of interface card ( 22 ) plugs into the pin socket ( 211 ) of PCB ( 21 ) to form a PCB components assembly ( 20 ), which will be assembled to the former portion of the bottom lid ( 12 ). Afterwards, the upper lid ( 11 ) shall face the former portion of bottom lid ( 12 ) and install on it.  
         [0026]    Please refer to FIGS. 4 and 7 shown of present invention, the elastic assembly ( 30 ) shall be assembled on top of the ribs ( 121 ) of the bottom lid ( 12 ). One flat portion ( 33 ) of the elastic assembly ( 30 ) leans against the positioned pillar ( 122 ). In the meanwhile, the other flat portion ( 33 ) is supported by the positioned pillar ( 122 ). One of the elastic extending portion ( 31 ) stays upturned, and the other elastic extending portion ( 32 ) inlayed the elastic positioned slot ( 123 ).  
         [0027]    Please refer to FIGS. 5 and 6 shown of present invention, the fixture assembly ( 40 ) shall be assembled above the interlock ( 124 ) of the bottom lid ( 12 ), herein the end with bayonet lock ( 43 ) shall face outwardly. Thus the board fence ( 13 ) shall face the interface card ( 132 ) through the plugging hole ( 132 ) and make the interface card ( 22 ) inserts to the plugging hole ( 132 ) of the board fence ( 13 ). Thus the board fence ( 13 ) will assemble on the bottom lid ( 12 ).  
         [0028]    Please refer to FIGS. 1, 2 and  7  shown of present invention, as the fixture assembly ( 40 ) is inside the boxed structure ( 10 ), the positioned block ( 44 ) of fixture assembly ( 40 ) will tightly wedge to the positioned slot ( 133 ) of board fence ( 13 ) to fix the fixture assembly ( 40 ) for avoiding its loose  
         [0029]    Please refer to FIGS. 7, 8 and  9  shown of present invention, as forcing the pin hole ( 42 ) of the fixture assembly ( 40 ) pulled outwardly from the boxed structure ( 10 ). Then the chamfered portion ( 411 ) on the extending portion ( 41 ) will contact the elastic extending portion ( 31 ) of elastic assembly ( 30 ). Thus, the extending portion ( 41 ) will press on the elastic assembly ( 30 ). In the meanwhile, the slot (not shown on the drawings) of PDA interface equipment ( 50 ) faces the interface card ( 22 ) of the boxed structure ( 10 ) in order to plug the interface card ( 22 ) into the slot (not shown on the drawings) of the PDA interface equipment ( 50 ). This connection makes interface card ( 22 ) keep the Inlay State in the slot (not shown on the drawings). Then, the PDA interface equipment ( 50 ) and the boxed structure ( 10 ) shall be press to each other in order to release the interface card ( 22 ) from the Inlay State. After stopping the pressing force, there will be a counteraction force from the elastic assembly ( 30 ) pushing on the fixture assembly ( 40 ). The elastic assembly ( 30 ) will drive its bayonet lock ( 43 ) to inlay the plug-in hole ( 51 ) of the PDA interface equipment ( 50 ). Thus, the PDA interface equipment ( 50 ) and the boxed structure ( 10 ) will be a connecting combination that uneasily falling off. On the contrary, in order to release the connecting combination of the PDA interface equipment ( 50 ) and the boxed structure ( 10 ), the bayonet lock ( 43 ), which wedged in the plug-in hole, shall be released. Moreover, the bayonet lock ( 43 ) shall be directly drawn out from the boxed structure ( 10 ). Similarly, the interface card ( 22 ) is removed from the PDA interface equipment ( 50 ).  
         [0030]    While this invention has been described in conjunction with particular embodiments, it is evident that alternatives, modifications and variations will now be apparent to those skilled in the art. Accordingly, the present invention is intended to embrace all such alternatives, modifications and variations and fall within the spirit and scope of the appended claims.
