ABSTRACT:
A fixing latch member for heat radiating board of CPU, including two latch boards, two linking levers and a controlling lever. Two ends of each latch board are respectively formed with a first and a second latch sections. The linking lever is passed through the latch board. A first end of the linking lever is hooked with the first latch section of the latch board. A second end thereof is formed with a connecting plate section having a locating hole and passed through the second latch section. Each end of the controlling lever is formed with an outward extending driving section fitted in the locating hole of the linking lever. The second latch section of the latch board resiliently abuts against the bottom of the driving section. By means of rotating the controlling lever, the driving sections thereof are rotated within the locating holes of the linking levers. At this time, the driving sections simultaneously downward press the second latch sections and lift the linking levers and drivingly lift the first latch sections, whereby the first and second latch sections are inward retracted toward each other so as to tightly latch the heat radiating board on the CPU.
