The body 31 extends downwardly from one side of the side plate 33 with two bent fixing pieces 39. The fixing piece 39 defines a fixing hole 391. During assembly, the plurality of fasteners 100 pass through the fixing holes 391 and 371 of the mounting bracket 30 and the fixing holes 110 and 1331 of the base 10 respectively, thereby mounting the mounting bracket 30 in the base 10.

The computer housing further includes a first expansion card 70 that can be inserted into the first riser card 50 to connect to the motherboard 20, and a plug-in card 60 can be inserted on the second riser card 60 to connect to the host The second expansion card 80 of the board 20. The width of the first expansion card 70 is greater than the width of the second expansion card 80. A mounting piece 71 is mounted on one side of the first expansion card 70. The mounting piece 71 is bent at one end to a fixing piece 711 which can be pressed against the blocking flap 335 of the mounting frame 30. A fixing post 7110 is protruded from the fixing hole 3351 of the fixing piece 711 corresponding to the blocking flap 335. The first expansion card 70 is also provided with an interface 73 connectable to an external device 101. A mounting piece 81 is mounted on one side of the second expansion card 80. One end of the mounting piece 81 is bent to a fixing piece 811 which can be pressed against the blocking flap 335 of the mounting frame 30. The fixing piece 81 A fixing post 8110 is protruded from the fixing hole 3351 of the blocking flap 335. The second expansion card 80 is also provided with an interface 83 connectable to an external device 102.

The computer housing further includes a fixing member 90 that is mounted in the base 10 in cooperation with the second expansion card 80. The fixing member 90 has a substantially rectangular plate body 91. A first fixing plate 93 and a second fixing plate 95 extend downward from the two side edges of the plate body 91. The locking holes 355 of the first fixing plate 93 corresponding to the mounting plate 35 of the mounting frame 30 form two fastening protrusions 931. Two fixing holes 951 are defined in the second fixing plate 95 corresponding to the fixing holes 61 of the second riser card 60. The fixing member 90 and one of the adjacent ends of the first fixing plate 93 and the second fixing plate 95 are bent by the one side plate 97. An inwardly convex bridge portion (not numbered) is formed on the side plate 97, and a mounting groove 973 is formed between the bridge portion and the side plate 97.

In use, one of the first expansion card 70 and the second expansion card 80 can be installed in the base 10.

Referring to FIG. 2 , when the first expansion card 70 is selected to be installed in the base 10 , the first riser card 50 is first inserted into the first connector 21 on the motherboard 20 . The two locking fasteners 100 respectively pass through the fixing holes 51 of the adapter card 50 and the fixing holes 353 of the mounting plate 35 of the mounting bracket 30, thereby fixing the adapter card 50 to the mounting bracket 30. One end of the mounting piece 71 on the first expansion card 70 passes through the mounting slot 351 of the mounting bracket 30. The fixing piece 711 is pressed against the blocking flap 335 of the mounting bracket 30 and is locked by the locking device 100. The fixing piece 711 is locked to the mounting bracket 30. Thus, the first expansion card 70 can be installed in the base 10.

As shown in FIG. 5, when the second expansion card 80 is selected to be installed in the base 10, the second riser card 60 is first inserted into the second connector 23 on the motherboard 20. The fixing protrusion 931 of the first fixing plate 93 of the fixing member 90 is engaged in the card slot 355 of the mounting plate 35 of the mounting frame 30. Two fasteners 100 respectively pass through the fixing member 90 and the second fixing plate The fixing hole 951 of the 95 and the fixing hole 61 of the second riser card 60 fix the second riser card 60 to the fixing member 90. One end of the mounting piece 81 on the second expansion card 80 passes through the mounting slot 973 of the fixing member 90. The fixing piece 811 is pressed against the blocking flap 335 of the mounting frame 30 and is locked by the locking device 100. The fixing piece 811 is locked to the mounting bracket 30. In this way, the second expansion card 80 can be installed in the base 10. At this time, the common width of the second expansion card 80 and the fixing member 90 is substantially equal to the first expansion card 70.

The second fixing member 70 can be a normal screw or a headless screw. The second fixing member 70 has a locking post 71 provided with an external thread 73. The nominal diameter of the external thread of the locking post 71 is substantially equal to the nominal diameter of the inner thread of the two fastening portions 53 near the end of the blocking end 51.

Referring to FIG. 3 and FIG. 4, when the fixing device 100 is used to fix the circuit board 10 to the base 30, firstly, the two fastening portions 53 of the first fixing member 50 are inserted through the circuit board. The first mounting hole 11 of the 10 is inserted into the second mounting hole 331 of the base 30. The stopper portion 51 of the first fixing member 50 is pressed against the top of the circuit board 10. The external threads of the locking post 70 of the second fixing member 70 are screwed along the internal threads 531 of the two fastening portions 53. The second fixing member 70 is screwed into the fixing portion of the first fixing member 50 because the nominal diameter of the end of the threaded portion 533 near the end of the stopping portion 51 is larger than the nominal diameter of the end portion of the stopping portion 51. During the process of the hole 57, the two fixing portions 70 of the second fixing member 70 are gradually forced to expand outward. When the second fixing member 70 is completely screwed into the fixing hole 57, the external thread 533 of the fixing portion 53 is pressed and engaged with the inner wall of the fixing post 33 of the base 30, thereby fixing the circuit board 10 to the same. Above the base 30.

In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application according to law. However, the above is only a preferred embodiment of the present invention, and is familiar with the present invention. Equivalent modifications or variations made by those skilled in the art in light of the spirit of the invention are intended to be included in the following claims.
