Abstract: A fastener module for portable computers that is disposed on the host of a portable computer to fasten the LCD with the host, no matter whether the LCD is closed directly or after rotating 180 degrees; the fastener module has a pivotable eccentric hook rod biased in a normal horizontal position when not affected by magnetic effect, when the LCD closes on the host of the computer, both sides of the hook rod are affected by the magnetic effect of the magnetic component on the LCD; since the pivot of the hook rod is designed eccentrically, the magnetic moment generated by the magnetic effect for each side of the hook rod is different, so that the hook rod changes its position instantly from the normal horizontal state to a vertical state and hooks within the opening of the LCD to fasten the LCD onto the host of the portable computer.
