[0031] The installation mechanism 2 includes two long rods 21, which are respectively rotatably connected to the left and right ends inside the support frame 1. A pressing plate 22 is fixedly connected to the surface of the long rod 21. One end of the front of the long rod 21 is fixedly connected to a dial plate 23. An adjusting screw 24 is threadedly connected inside one end of the dial plate 23. An adjusting screw rod 25 is threadedly connected to the middle inside the pressing plate 22. The bottom end of the adjusting screw rod 25 is rotatably connected to a pressing strip 26. Two limiting strips 29 are respectively fixedly connected to the two ends of the top of the pressing strip 26. A supporting strip 28 is arranged at the bottom of the pressing strip 26. The bottom of the supporting strip 28 is fixedly connected to the limiting strip 29. The supporting strip 28 and the circuit board body 27 are alternately distributed and arranged between the two circuit board bodies 27.

[0032] Furthermore, through holes are respectively opened at the front and rear ends of the pressing plate 22, and the surface of the limiting strip 29 penetrates through the through holes respectively opened at the front and rear ends of the pressing plate 22. Rotate the long rod 21 to open the pressing plate 22, then arrange the circuit board body 27 and the supporting strip 28 in sequence, and then reverse-rotate the long rod 21 to drive the pressing plate 22 to rotate, thereby driving the pressing strip 26 to clamp the surface of the circuit board body 27. At this time, use the adjusting screw 24 to threadedly tighten and fix the dial plate 23 and the support frame 1, so as to fix the circuit board body 27 after installation.

In the process, the number of layers of the circuit board clamped can be adjusted by rotating the adjusting screw 25 to drive the pressure strip 26 to move.

[0037] In addition, when the circuit board body 27 is used for protection, the dustproof net 33 is used to prevent dust from forming on the bottom end of the circuit board body 27. When the dustproof net 33 needs to be cleaned, the T-shaped plate 37 is pulled open to drive the card strip 38 to move inside the card seat 36 and disengage from the card slot inside the bottom frame 31 and release the restriction of the card seat 36. The T-shaped rod 35 is driven to move under the elasticity of the spring 34, and then the card seat 36 is driven to move and leave the surface of the card frame 32, so that the dustproof net 33 can be disassembled and the corresponding cleaning operation can be performed.
