The prism structures intersect at the intersection of the three cylindrical outer surfaces. The supporting member 34 is attached to the edge of the connecting member 30. The support member 34 is capable of engaging the connector 30 to raise the case 20 so that the bottom surface of the case 20 does not contact the underlying surface on which it is placed. Further, the box body 20 after lifting increases the heat dissipation space, and a cleaning blind area cannot be formed below the box body 20.

According to a preferred embodiment, the connecting element 30 is provided with a crash bar. Because the connecting piece 30 is a protruding structure compared with the box body 20, the connecting piece is easily damaged by collision, and the anti-collision strip is attached to the surface of the connecting piece 30 to protect the device and an external collision object.

When the device is used, the integrated board 10 is connected to the box surface 21 through the plug-in 13 on the integrated panel 12, and then the connecting piece 30 is used for sequentially inserting the rest of the box surfaces 21 into the first slot on the connecting piece 30, so that the box body 20 with the integrated board 10 arranged inside can be formed. When the integrated board 10 needs to be maintained, the box body 20 can be disassembled only by forcibly detaching the connecting piece 30, so that the integrated board 10 is maintained.
