BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present invention relates to a fixture of a disk drive, and more particular to a modular structure fixed inside a computer case without any screw. 
         [0003]    2. Description of Related Art 
         [0004]    Hardware of a computer generally includes: a main board, interface cards, hard drives, a CD-ROM, etc. All these modules are integrated in a computer case. Because the floppy disk drive, the hard drive, and the CD-ROM can be selectively configured, the housings of the floppy disk drive, the hard drive, and the CD-ROM are usually configured inside the computer case firstly for easy assembly and subsequent expansion, and the floppy disk drive, the hard drive, and the CD-ROM can be assembled or disassembled or expanded via the housings. 
         [0005]    Presently, a conventional disk drive fixing method includes: fixing a housing inside a computer case via screws; then setting a disk drive onto the housing, wherein the disk drive is fixed onto the housing by the screws, so that the disk drive is fixed inside the computer case. However, the fixing method has some disadvantages, for example, a screwdriver must be used when assembling or disassembling the disk drive. Thus, the procedure is complex and taxing, it is hard to increase the production efficiency. 
         [0006]    Based on the aforementioned matter, some disk drive fixing methods which are easy for assembly or disassembly are proposed. One of the methods includes: setting two sliding bars on a disk drive housing (a position inside a computer case to be set with a disk drive); and respectively setting two sliding rails on two sides of the disk drive; sliding the disk drive onto the disk drive housing. However, when assembling the disk drive, also, a screwdriver must be used to tighten the screws to fix the sliding bars on the computer case, so the procedure is complex and time consuming. Thus, it is necessary to provide a low-cost and timesaving fixing method for disk drives. 
         [0007]    Consequently, because of the technical defects of described above, the applicant keeps on carving unflaggingly through wholehearted experience and research to develop the present invention, which can effectively improve the defects described above.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0027]    Please refer to  FIG. 1 , a fixture  10  which fixes a disk drive inside a computer case is provided. The fixture  10  includes a body  11 , and a plurality of screw eyes  12  are set on the body  11 . In the present embodiment, there are four screw eyes  12  which are respectively distributed on the four corners of the body  11 . The fixture  10  may be fixed on the disk drive by screws engaging with the screw eyes  12 . 
         [0028]    The body  11  further includes a first surface  111  and a second surface  112  opposite to the first surface  111 . A plurality of positioning braces  13  and an elastic buckle  14  extend from the first surface  111 . There are two positioning braces  13 , and the elastic buckle  14  is located between the two positioning braces  13 . The second surface  112  is used to be fixedly combined with the disk drive, and the first surface  111  is used to be combined with the computer case. 
         [0029]    The positioning brace  13  is an L-shaped bent piece, which is in-molded with the body  11  and includes a first bent piece  131  and a second bent piece  132 . The first bent piece  131  is perpendicular to the second bent piece  132 . The first bent piece  131  extends perpendicularly for a length from the first surface  111 , and then is bent to form the second bent piece  132 . The second bent piece  132  is parallel with the first surface  111  and is bent towards the direction of the arrowhead A as shown in the  FIG. 1 . Preferably, the positioning brace  13  includes a guiding rib  133  which is formed on a surface of the second bent piece  132 , and the surface is adjacent to and parallel with the first surface  111  of the body  11 . The guiding rib  133  is perpendicular to the first bent piece  131  and the second bent piece  132  respectively. The guiding rib  133  and the first bent piece  131  are set on a same side. 
         [0030]    The elastic buckle  14  is set in a hollow-out portion  15  defined on the first surface  111  of the body  11 , and the hollow-out portion  15  includes an inside wall  151 . Preferably, the elastic buckle  14  is an elastic hook, which includes an elastic arm  141  and a hook  142 . The elastic arm  141  extends from the inside wall  151  to a direction parallel with the first surface  111 , and the hook  142  is set on the end of the elastic arm  141 . The hook  142  extends towards the direction perpendicular to the first surface  111 , one side of the hook  142  indicated by arrowhead A is arc-shaped. 
         [0031]    Preferably, the body  11  is made of flexile material, such as plastic, and metal is also acceptable. 
         [0032]    Please refer to  FIG. 2  and  FIG. 3 . A positioning hole  23  is defined in a side wall  21  of a computer case  20  to cooperate with the positioning brace  13 , and a hook hole  24  is defined in the side wall  21  to cooperate with the elastic buckle  14 . A guiding slot  231  is set inside the positioning hole  23  to receive the guiding rib  133  of the positioning brace  13  in assembly. In the present invention, the computer case  20  may be fixed two fixtures  10  on. 
         [0033]    Please refer to  FIG. 4 . In assembly, the fixture  10  is fixed onto a disk drive  40  by screws  30 . The disk drive  40  is standard, and general screw holes  42  are defined in the disk device  40 . The position and the size of the screw holes  12  of the fixture  10  correspond to the screw holes  42  of the disk drive. The screws  30  are screwed so that the fixture  10  is fixed onto a disk drive  40 , and the positioning brace  13  and the elastic buckle  14  are all towards a direction away from the disk drive  40 . 
         [0034]    Please refer to  FIG. 5  showing the fixture  10  combined with the disk drive  40 , to  FIG. 6 , and to  FIG. 7 , showing a partially enlarged view of part F. The fixture  10  combined with the disk drive  40  is fixed onto the side wall  21  of the computer case  20 . The fixing method includes: inserting the positioning brace  13  of the fixture  10  into the positioning hole  23  along the direction of the arrowhead A, extending the elastic buckle  14  into hook hole  24 , extending the second bent piece  132  of the positioning brace  13  outwards from positioning hole  23 , and then pushing the second bent piece  132  into positioning hole  23  along the direction of the arrowhead A until the guiding rib  133  is tightly inserted into guiding slot  231  and blocked on the outside surface of side wall  21 . During this operation, the elastic buckle  14  may automatically attach on side wall  21  because of the arc shape of one side of hook  142 , until the hook  142  is received in hook hole  24  to hook the outside surface of side wall  21  and reaches the blocking position. Thus, the fixture  10  combined with the disk drive  40  is fixed inside the computer case  20 . 
         [0035]    In disassembly, press the hook  142  of the elastic buckle  14  from top to down to easily withdraw the hook  142  from the hook hole  24 . Then push the positioning brace  13  along a direction opposite to the direction of the arrowhead A to withdraw the guiding rib  133  from the guiding slot  231 , and from the positioning hole  23 . Thus, the disk drive  40  is disassembled from the side wall  21  of the computer case  20 . 
         [0036]    The positioning brace  13  and the elastic buckle  14  of the fixture  10  are designed as aforementioned so that the process that the disk drive  40  is assembled inside the computer case  20  is very simply, timesaving and low-cost, which is suit to be widely applied. 
         [0037]    While the invention has been described in terms of what is presently considered to be the most practical and preferred embodiments, it is to be understood that the invention needs not be limited to the disclosed embodiment. On the contrary, it is intended to cover various modifications and similar arrangements included within the spirit and scope of the appended claims which are to be accorded with the broadest interpretation so as to encompass all such modifications and similar structures.
