The inner side surfaces of the side panels 2 protrude opposite the card slots 11 to form card blocks, and the card blocks are inserted into the card slots 11 and are fixedly connected to the card slots 11.

[0024] In this embodiment, one side of the top frame 3 is fixedly connected to the side panel 2 through a hinge. After removing the side panel 2 connected to the top frame 3, slots 9 are provided on the top surfaces of the remaining side panels 2. The bottom surfaces of the top frame 3 protrude opposite the slots 9 to form plug-in columns, which are inserted into the corresponding slots 9.

[0025] In this embodiment, a plurality of positioning grooves 8 are provided on the inner side surface of the side plate 2 in the length direction, and both ends of the shielding plate 7 protrude to form positioning portions 10 , which are inserted into the corresponding positioning grooves 8 .
