1. A damper structure in contact with a connection unit for coupling a first coupling structure part and a second coupling structure part, the damper structure comprising:
a damper part formed of an elastic material and having a quadrangular recess at a middle portion of one surface; and
a fixing part having a quadrangular planar shape and inserted into the recess of the damper part so as to be coupled to the damper part, and having an outer surface which is a flat surface, does not face the recess on the opposite side of the recess and protrudes outward from the damper part,
wherein when the connection unit is inserted and rotated in one direction, due to the pressure applied to the outer surface of the fixing part by the connection unit, the fixing part compresses the damper part until the outer surface is positioned into the recess of the damper part.
