The side wall portion 621 defines a limiting slot 621 a between the first socket portion 623 and the second socket portion 624. With reference to FIG. 7, the height adjusting member 64 is rotatably disposed on the second side pressing member 62 relative to the second side pressing member 62 and has a first sleeve portion 623 and the second sleeve passing through the first sleeve connecting portion 623. A threaded portion 641 of the connecting portion 624 and a head portion 642 connected to a top end of the threaded portion 641. The head portion 642 is located between the bottom side of the bridge plate 3 and the first socket portion 623 and abuts against the first socket portion 623. The head 642 has a groove 642 a exposed on the top side of the bridge plate 3 through the through groove 312. An operator can use a tool such as a screwdriver to align the side groove 611b of the sliding plate portion 611, insert a screwdriver into the groove 642a through the through groove 312, and drive the height adjustment member 64 to rotate. The third side pressing member 65 passes through the limiting groove 621 a, and has a guide portion 651 screwed to the threaded portion 641 of the height adjusting member 64, and a pressing portion connected to the guide portion 651. 652. When the height adjusting member 64 is operatively rotated relative to the second side pressing member 62, the threaded portion 641 synchronously drives the third side pressing member 65. Since the third side pressing member 65 is restricted by the two sides of the limiting groove 621a and cannot be rotated synchronously with the height adjusting member 64, the third side pressing member 65 can further be in the limiting groove with respect to the height adjusting member 64. 621 a moves up and down to press against the top surface 81 of the display card 8, so that the display card 8 is fixedly inserted into the second slot seat 721. The elastic member 66 is sleeved on the height adjusting member 64, and both ends of the elastic member 66 abut against the first socket portion 623 and the guide portion 651 respectively, and provides an elastic force to assist the third side pressing member 65 against the display. Card 8.

Referring to FIG. 8, a second embodiment of the adjustable fixing frame 2 is shown. This second embodiment is substantially the same as the first embodiment, except that the second embodiment can simultaneously fix two display cards 8 in the installation space 11 of the computer mechanism 100 (see FIG. 1). Specifically, the second embodiment includes a bridge plate 3, a positioning frame 4, two first pressing units 5, and two second pressing units 6. The bridge plate 3 is provided with six sliding grooves 311 and two through grooves 312. The two sliding grooves 311 near the clamping portion 33 of the bridge plate 3 and a through groove 312 between the two sliding grooves 311 are defined as the first guide groove group 30a. The two sliding grooves near the center of the bridge plate 3 The slot 311 and the other through slot 312 are the second guide slot group 30b, and the two sliding slots 311 near the connection portion 34 of the bridge plate 3 are the third guide slot group 30c.

The first pressing units 5 are respectively disposed in the second guide groove group 30b and the third guide groove group 30c, and each of the first pressing units 5 includes a sliding member 61 and a first side pressing member 52. The structure of the sliding member 61 and the manner of being disposed in the sliding groove 311 are the same as those of the sliding member 61 in the first embodiment. The structure of the first side pressing member 52 is simpler than that of the first embodiment, and can also be locked to the sliding member 61 by two locking members and can be abutted against the display card 8 by the sliding member 61. First side 82.

The second pressing units 6 are respectively disposed on the first guide groove group 30a and the second guide groove group 30b, and the structure of each second pressing unit 6 and the manner of being disposed on the slide groove 311 are the same as those of the first guide groove group 311. The second pressing unit 6 of the embodiment is the same, so the details are not described again.

That is, in this embodiment, the first pressing unit 5 provided in the second guide groove group 30b can cooperate with the second pressing unit 6 provided in the first guide groove group 30a to fix one of them. For the display card 8, the first pressing unit 5 provided in the third guide groove group 30c can cooperate with the second pressing unit 6 provided in the second guide groove group 30b to fix another display card 8 together. Compared with the first pressing unit 5 of the first embodiment, the first pressing unit 5 is fixedly connected to the bridge plate 3. The first pressing unit 5 of the second embodiment can be along the bridge plate 3 in the sliding grooves 311. Moving in the length direction, so that the adjustable fixing frame 2 of the second embodiment can more freely fix the display cards 8 of different plug-in positions or the display cards 8 of different width sizes.

In addition, compared with the positioning frame 4 of the first embodiment, the positioning frame 4 of the second embodiment reduces the design of the extension plate 41 (see FIG. 5), and forms a plurality of through holes 421 in the supporting plate 42. The clamping portion 33 of the bridge plate 3 is fastened to any one of the through holes 421 by fasteners such as screws, so that the bridge plate 3 can also be in the first direction D1 with respect to the display card 8 ( (See Figure 1).

In summary, the adjustable fixing frame 2 of the computer mechanism 100 of the present invention is slidably disposed on the bridge plate 3 through the second side pressing member 62, so that the second side pressing member 62 can cooperate with the first side pressing member 52. Holding the display cards 8 of different widths together can prevent the display card 8 from tilting when the computer mechanism 100 shakes. In addition, the third side pressing member 65 can be guided up and down by the height adjusting member 64 to press the display of different heights. The card 8 enables the display card 8 to be firmly inserted into the second socket seat 721 to avoid the occurrence of poor contact caused by loosening, so the purpose of the present invention can be achieved.

However, the above are only examples of the present invention. When the scope of implementation of the present invention cannot be limited in this way, any simple equivalent changes and modifications made in accordance with the scope of the patent application and the content of the patent specification of the present invention are still Within the scope of the invention patent.
