COUPLING ASSEMBLY HAVING DUAL-SCREW ENGAGEMENT STRUCTURE

原文（中国語）

An embodiment relates to a coupling assembly having a dual-screw structure. The coupling assembly includes: a sliding body formed in a planar shape in a longitudinal direction; an upper support coupled to the sliding body; and a lower support coupled to the sliding body. The sliding body has a plurality of projections formed on an inner surface thereof. The upper support is brought into close contact with and fixed to an upper surface of an object to which the coupling assembly is mounted, and includes an upper horizontal support formed in a plate shape in a horizontal direction, and an upper vertical support formed in a plate shape in a direction vertically downward from the upper horizontal support such that a part of the upper support overlaps and is coupled with the sliding body.
