Beschreibung
Zusammenfassung:	Disclosed is a combined nut, comprising an inner sleeved nut (1) and an outer sleeved nut (2), wherein the inner sleeved nut (1) is in the shape of a truncated cone and is provided with an inner hole along the axis, an inner thread is provided at the inner hole, and a side face of the inner sleeved nut (1) is provided with a slot (3); and the outer sleeved nut (2) is sheathed on an outer side of the inner sleeved nut (1), and a tapered structure matching the inner sleeved nut (1) is arranged on an inner side of the outer sleeved nut (2). During tightening, since the inner sleeved nut (1) has the slot (3), and the outer sleeved nut (2) further utilizes a counter-acting force from a connected object and the feature of being tapered, under a force, a gap between the nut and a screw rod is minimized, such that a gap between the nut and a bolt is minimized therewith; and the inner sleeved nut (1) can tightly hold the bolt so as to prevent the nut from becoming loose or unscrewed, and the nut is not easily unscrewe
