[0031] Reference Figure 2-4A mounting plate 9 is provided at the bottom of the circuit board 1, and the mounting plate 9 is used to fix the circuit board 1. Four card slots 10 are provided on the top of the mounting plate 9, and the card slots 10 are used to engage with the card block 6 to fix the circuit board 1 and the mounting plate 9. A heat dissipation component is provided on the top of the circuit board 1. The card block 6 is slidably connected to the inside of the mounting box 2. The mounting box 2 is used to limit the card block 6. The opposite sides of the two card blocks 6 respectively penetrate the left and right sides of the mounting box 2, which can facilitate the card block 6 to engage with the card slot 10 to connect the circuit board 1 and the mounting plate 9. The pressing plate 4 is slidably connected to the fixing rod 8 On the outside, the fixing rod 8 and the installation box 2 cooperate with each other to limit the pressure plate 4 more stably. The side of the card block 6 away from the spring 7 is designed to be an inclined surface, and the bottom of the pressure block 5 is designed to be an inclined surface, which can make the pressure block 5 squeeze the card block 6 to drive the card block 6 to move.
