an auxiliary member having first and second rectangular through-holes positioned apart from each other to be exposed to an outside through the longitudinal hole, wherein the auxiliary member is disposed on a lower surface of the main body; and

a protective film disposed to cover bottoms of the first and second rectangular through-holes,

wherein the auxiliary member has a first one-side-open rectangular through-hole at one front portion of the auxiliary member, which is adjacent to the first rectangular through-hole, and

wherein the auxiliary member has a second one-side-open rectangular through-hole at one rear portion of the auxiliary member, which is adjacent to the second rectangular through-hole.
