The heat-dissipating filter screen 17 is made of metal material. When the computer motherboard is installed, the computer motherboard is clamped in the first soft cushion block 10 in the clamping outer frame 9 on the upper side of the fixed supporting block 7. The first soft cushion block 10 squeezes and fixes the computer motherboard, and then the fastening screw 11 is rotated by the rotating handle 20. The fastening screw 11 further drives the sliding supporting block 8 to move. The first soft cushion block 10 in the clamping outer frame 9 on the upper side of the sliding supporting block 8 squeezes and fixes the other end of the computer motherboard. Finally, the fastening spring 12 drives the second soft cushion block 14 on the side wall of the fastening pressure plate 13 to squeeze and fix the front and back sides of the computer motherboard, so that the computer motherboard can be firmly fixed, and at the same time, the computer motherboards of different sizes and models can be fixed. The damping spring 2 can have the function of buffering when the computer mainboard topples. The damping spring 2 can absorb part of the impact force, which can effectively prevent the internal computer mainboard from being greatly impacted when the computer mainboard topples and thus causing the computer mainboard to be damaged. The two second supporting door frames 5 are moved from both sides to the middle. The magnetic suction plates 18 on the upper side of the second supporting door frames 5 are mutually attracted. The two second supporting door frames 5 are fixed together, so that the dustproof filter screen 6 covers the upper side of the computer motherboard. The dustproof filter screen 6 can have the function of dust prevention for the computer motherboard. The heat-dissipating filter screen 17 can have the function of heat dissipation, and at the same time, can have a certain dust prevention effect. The heat-dissipating fan 16 can improve the heat dissipation efficiency of the computer motherboard.

[0040] As shown in FIGS. 1 and 2, the first supporting door frame 4 is fixedly connected in the first sliding groove 301, and the second supporting door frame 5 is slidably connected with the first sliding groove 301.

When the second supporting door frame 5 moves to both sides, the dustproof filter screen 6 can be folded.

[0041] As shown in FIGS. 1, 6 and 8, there are four fastening springs 12 in total, and the cross section of the fastening pressure plate 13 is provided in an L-shaped structure. The fastening springs 12 drive the fastening pressure plate 13 to be pulled from the front and back sides to the middle, so that the second soft cushion block 14 can squeeze and fix the computer motherboard.

[0042] As shown in FIG. 2, the first sliding groove 301 is provided on the front side wall of the second fixing plate 3 and the rear side wall of the second fixing plate 3, respectively, and the cross section of the first sliding groove 301 is provided in a T-shaped structure. The lower end of the damping spring 2 is fixedly connected with the upper side wall of the first fixing plate 1, and the upper end of the damping spring 2 is fixedly connected with the lower side wall of the second fixing plate 3. The first fixing plate 1 is fixedly connected to the inner side wall of the computer mainboard in a manner of gluing or screw fixing, and the damping spring 2 has the function of shock absorption and buffering.

[0043] As shown in FIGS. 2 and 7, the second sliding groove 302 is provided on the upper side wall of the second fixing plate 3, and the cross section of the lower end of the sliding supporting block 8 is provided in a T-shaped structure. The sliding supporting block 8 slides along the second sliding groove 302, so that the first soft cushion block 10 in the clamping outer frame 9 of the upper side of the sliding supporting block 8 can squeeze and fix the other end of the computer motherboard.

[0044] As shown in FIGS. 3, 4 and 5, the side wall of the upper end of the second supporting door frame 5 is fixedly connected with a magnetic suction plate 18, and there are two first supporting door frames 4 and two second supporting door frames 5. The two second supporting door frames 5 are moved from both sides to the middle. The magnetic suction plates 18 on the upper side of the second supporting door frames 5 are mutually attracted. The two second supporting door frames 5 are fixed together, so that the dustproof filter screen 6 covers the upper side of the computer motherboard.

[0045] As shown in FIG. 7, the fastening screw 11 is riveted with the threaded hole of a long limit block 19, and the right end of the fastening screw 11 is fixedly connected with a rotating handle 20. The fastening screw 11 is rotated by the rotating handle 20, so that the position of the sliding supporting block 8 is further adjusted, and the first soft cushion block 10 in the clamping outer frame 9 of the upper side of the sliding supporting block 8 squeezes and fixes the other end of the computer motherboard.
