During the process of the cover plate covering the mainboard, the oblique notch on the cover plate contacts the locking rod, driving the locking rod to move away from the cover plate. When the lock hole on the cover plate moves to be concentric with the locking rod, the lock rod is driven to move toward the inside of the lock hole under the elastic force of the first spring, thereby completing the fixation of the cover plate, and further completing the rapid fixation of the mainboard.

[0015] 3. After the mainboard is fixed, the present invention presses the lever inwardly so that the lever drives the locking block to move into the second slide slot, then the heat sink is plugged into the notch, and then the lever is released. Under the elastic force of the second spring, the ground hole locking block moves into the plug-in slot, thereby completing the installation of the heat sink, and the second baffle is pulled outward, and then the pull rod drives the buckle plate and the dredging pipe to move toward the through hole, so that the dredging pipe dredges the through hole, cleans the dust in the through hole, improves the air circulation of the through hole, and thus ensures the heat dissipation effect. By using the buffer component, the chassis is placed on the ground, the chassis is buffered, and the collision between the chassis and the ground is avoided, which may cause damage to the internal components of the chassis.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
