[0003] At present, in order to reduce the impact of the external environment on the circuit board, the existing circuit board needs to be installed inside the chassis for storage during use. The common way to fix the motherboard is to set a number of conductive copper pillars on the shell of the computer device as fixing components, and the motherboard is provided with a number of through holes corresponding to the copper pillars. The circuit board is placed on the copper pillars and kept at an appropriate distance from the shell. Then, a number of bolts are respectively passed through the through holes of the motherboard and locked on the copper pillars, so that the motherboard is supported by the copper pillars and keeps a distance from the shell, so as to avoid the solder pin contacts on the back of the motherboard directly contacting the shell and causing a short circuit.
