[0013] (1) Through the designed dust baffle, slide plate, slide bar, spring and mounting plate, a plurality of expansion interfaces are installed on the main board body to achieve expansion by connecting with a plurality of external devices. The dust baffle is installed on the expansion interface by sliding with the slide bar and the slide plate. When expansion plugging is required, the dust baffle is pushed up to open the port for plugging. The interface without expansion connection slides downward under the elastic squeezing action of the spring. The dust baffle is blocked at the port of the expansion interface to block and isolate the port of the expansion interface to prevent external dust and debris. Entering into the interior of the expansion socket, resulting in poor contact during subsequent expansion and plugging, improves the expansion stability of the motherboard, through the designed anti-slip pad and arc groove, so that the finger presses in the arc groove to push the dust baffle, through the designed rubber pad, the rubber pad has good flexible deformation ability, set between the dust baffle and the expansion socket, further improve the sealing isolation effect, through the designed adjusting screw sleeve and external thread, the adjusting screw sleeve and the external thread are screwed to adjust the position, so as to adjust the compression of the spring and achieve the best elastic extrusion effect.
