[0037] Then, by pulling the pull rod 401, the sliding plate 406 is driven to slide and compress the fixed spring 407, and the sliding rod 403, the clamping block 409 and the movable sponge block 402 are driven to slide to a suitable position, and then the PCBA board is placed in the reserved slot 5 in sequence, and then the pull rod 401 is released, and the elastic force of the fixed spring 407 is used to make the sliding plate 406 slide and drive the sliding rod 403 and the clamping block 409 to slide, and then the two ends of the PCBA board can be flexibly clamped and fixed by the movable sponge block 402 and the fixed sponge block 6, so as to avoid damage caused by sliding of the PCBA board or even collision with each other due to accidental collision during transportation;

[0038] Then, the box plate 2 is closed. At this time, the U-shaped sealing ring 1 is used to improve the sealing between the box plate 2 and the box body 3 after the box plate 2 is covered, and the air flow inside and outside the box body 3 is reduced. Then, when the PCBA board is stored, the silicone dehumidification plate 703 is used to absorb the moisture inside the box body 3 to ensure the dryness of the inside of the box body 3 and reduce the adverse effects of moisture on the storage of the PCBA board. At the same time, the card plate 702 can be rotated regularly to the inside of the card slot 706, and then the U-shaped finger groove 704 is used to facilitate the user to slide the silicone dehumidification plate 703 out of the placement frame 701 from here, so as to facilitate the replacement of the saturated silicone dehumidification plate 703, and ensure good dryness and dehumidification of the inside of the box 3.
