1. A coupling assembly, comprising:
a first plate structure;
a second plate structure; and
a coupler coupling the first plate structure and the second plate structure, wherein
the first plate structure includes a first insertion hole and a first serration located on a first outer surface of the first plate structure and surrounding the first insertion hole, the first outer surface facing away from the second plate structure,
the second plate structure includes a second insertion hole in having an inner diameter smaller than an inner diameter of the first insertion hole, and
the coupler includes:
a contact structure including a second serration and a third insertion hole, the second serration contacting the first outer surface of the first plate structure and meshing with the first serration of the first plate structure,
a shaft structure which contacts an inner circumferential surface of the second insertion hole and an inner circumferential surface of the third insertion hole and does not contact an inner circumferential surface of the first insertion hole when inserted through the first, second and third insertion holes, the shaft structure including a fixed engagement portion fixedly engaged with one of a second outer surface of the second plate structure and a third outer surface of the contact structure, and
a pressing structure engaged with the shaft structure and pressing an other of the second outer surface of the second plate structure and the third outer surface of the contact structure.
