Drawer of computer desk

Abstract

An improved drawer of the computer desk allows assembling of a combined drawer unit underneath the computer desk. The drawer unit consists of a mother drawer, a subdrawer and several guideway assemblies. Both sides of the mother drawer are assembled via a guideway assembly onto the computer desk. The subdrawer is assembled at inner edge of the mother drawer. The guideway assembly is separately set between two external sides and an inner side corresponding to the mother drawer. The mother drawer and subdrawer can form a combined sleeving structure to save space and increase use convenience.
