The first body includes a first base defining a first through hole at a center of the first base and a first protrusion protruded from a boundary of the first through hole. The second body includes a second base defining a second through hole at a center of the second base and a second protrusion protruded from a boundary of the second through hole. The first protrusion defines an insert groove at a surface which is opposite to the second protrusion. The second protrusion is configured to be inserted into the insert groove to be combined with the first protrusion.
