An article support rack with accessorial article support racks directly assembled therewith includes a main article support rack, at least one conical lantern ring and at least one accessorial article support rack with split rings. Several flutes are defined in the support legs of the main article support rack. The conical lantern ring consists of two taper-collets and at least one protuberant rib is formed on an inner wall of the taper-collets so that the flutes engage with the ribs when two taper-collets are assembled to be a conical lantern ring around the support leg of the main article support rack, thereby achieving the function of stopping slip up and down. Since the accessorial article support rack can be assembled directly to the main article support rack without disassembling the main article support rack in advance, the extension function of the article support rack is greatly improved.
