A notebook computer expansion module is described. The notebook computer expansion module has a support rest, an adjusting handle, a cable, a base, and an adjustable rotational shaft. The adjusting handle coupled to one side of the support rest allows a user to operate conveniently the notebook computer expansion module. The cable is coupled between the adjusting handle and the adjustable rotational shaft for releasing the adjustable rotational shaft so as to rotate the support rest on the base. The adjusting shaft further includes a ratchet fixed on the base, a fixing device, and a fixing plate. The fixing device is coupled to the fixing plate when the fixing device is coupled to the ratchet so as to enhance an engagement strength between the fixing device and the ratchet.
