[0023] In this embodiment, support blocks 2 are set at the four corners of the top of the base 1, and a support plate 3 is set on the top of the support block 2. By placing the mainboard on the support platform 8, the support plate 3 is adjusted so that the limit blocks 4 set at one end of the support plate 3 fix the four corners of the mainboard.

A dust collecting electrode tube 7 is arranged at the center of the top of the base 1, and the dust with added electrons is adsorbed by the dust collecting electrode tube 7. When the dust is sucked into the dust collecting electrode tube 7, the demagnetizing block 9 arranged at the bottom of the support platform 8 is used to remove the electrons attached to the dust, and the dust that loses the electron traction falls through the gap between the through-hole mainboard and the fixed frame, which solves the problem that the surface of the mainboard is easily attached to dust during use, and the dust accumulates on the mainboard over time, resulting in poor heat dissipation effect of the mainboard.

The suction cup 5 is attached to the surface of the host, and an exhaust pipe 12 provided on the outer wall of the blocking block 11 is rotated to discharge the air in the suction cup 5 through the exhaust hole. When the suction cup 5 is adsorbed on the surface of the host, the exhaust pipe 12 is rotated to close the exhaust hole, thereby solving the problem that the operation of the traditional fixing frame is cumbersome during the installation process and it is difficult to clean the motherboard later.

[0030] Example 4

[0031] like Figure 1-4 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the top of the limit block 4 is fixedly connected with a first telescopic rod 13, the output end of the first telescopic rod 13 is fixedly connected with a clamping plate 14, slots 15 are provided at both ends of the outer wall of the support plate 3, the inner wall of the slot 15 is plugged with a pin 16, one end of the outer wall of the pin 16 is plugged with one side of the support block 2, the four sides of the bottom of the base 1 are fixedly connected with a limit box 17, the two sides of the inner wall of the limit box 17 are fixedly connected with a second telescopic rod 18, and the output end of the second telescopic rod 18 is fixedly connected with a fixing plate 19.

[0033] The working principle of the computer motherboard fixing bracket is described in detail below.

[0034] like Figure 1-4As shown, by arranging support blocks 2 at the four corners of the top of the base 1, a support plate 3 is arranged on the top of the support block 2, by placing the mainboard on the support platform 8, by arranging slots 15 at both ends of the outer wall of the support plate 3, when the support plate 3 is stretched to an appropriate length, the pin 16 is inserted into the slot 15 through one side of the support block 2, so as to fix the support plate 3, by arranging a first telescopic rod 13 on the top of the limit block 4, pulling the first telescopic rod 13, and using the clamping plate 14 arranged at the output end thereof to clamp and fix the four corners of the mainboard, by arranging a limit box 17 at the four corners of the bottom of the base 1, a second telescopic rod 18 is arranged on both sides of the inner wall of the limit box 17, by pulling the fixing plate 19 arranged at the output end of the second telescopic rod 18, the four sides of the mainboard are fixed by using the fixing plate 19, by arranging a fixing block 10 at the bottom of the base 1, a blocking block 11 is arranged at the bottom of the fixing block 10, and a suction cup 5 is arranged at one end of the blocking block 11, by The disk 5 is attached to the surface of the main machine. At this time, the exhaust pipe 12 arranged on the outer wall of the rotating block 11 allows the air in the suction cup 5 to be discharged through the exhaust hole. When the suction cup 5 is adsorbed on the surface of the main machine, the rotating exhaust pipe 12 closes the exhaust hole, which solves the problem that the traditional fixing frame is complicated to operate during the installation process, and it is difficult to clean the main board later. By setting corona electrodes 6 on the four sides of the top of the base 1, the corona electrodes 6 are started to add electrons to the dust attached to the surface of the main board. By setting a dust collecting electrode tube 7 at the center of the top of the base 1, the dust with added electrons is adsorbed by the dust collecting electrode tube 7. When the dust is sucked into the dust collecting electrode tube 7, the demagnetizing block 9 arranged at the bottom of the support platform 8 is used to remove the electrons attached to the dust, and the dust that loses the electron traction falls through the gap between the main board and the fixing frame. This solves the problem that the surface of the main board is easily attached to dust during use. Over time, dust accumulates on the main board, resulting in poor heat dissipation effect of the main board.

[0035] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
