When the board 20 is pushed toward the side wall 123 along the notch direction of the card slot 120, the second sub-slot 212 moves toward the side wall 123, and the second sub-slot 212 is capable of guiding the board 20 and enabling the board 20 to be clamped with the card slot 120 and the second sub-slot 212 to be clamped with the side wall 123 due to the size of the second sub-slot 212 and the size of the side wall 123.

In some embodiments, the thicknesses of the top wall 122, the bottom wall 121 and the side wall 123 are consistent, the length of the first sub-slot 211 is greater than the length of the top wall 122, the width of the first sub-slot 211 is greater than the width of the top wall 122, so that the top wall 122 can pass through the first sub-slot 211, the width of the second sub-slot 212 is matched with the thickness of the side wall 123, so that the side wall 123 is clamped in the second sub-slot 212 after assembly, and the board card 20 cannot shake.
