Fixing structure

Abstract

A fixing structure includes a lower plate, an upper plate, an elastic structure, and a nut. The upper plate located over the lower plate. The elastic structure runs through the upper plate. The elastic structure includes an elastic portion, a bolt portion connected to an end of the elastic portion, and a screwing portion connected to the other end of the elastic portion. The elastic portion elastically stretches and compresses along a direction. The screwing portion is fixed to the lower plate and remains stationary relative to the lower plate. The nut is threadedly engaged with the bolt portion and abuts against a top surface of the upper plate. The nut rotates relative to a rotation axis parallel to the direction and drives the upper plate to move toward the lower plate. The elastic portion elastically stretches along the direction.
