A casing includes a base plate and a supporting post extending upwardly from the base plate. The base plate and the supporting post are integrally formed as a single monolithic piece from the same material. The supporting post axially defines a fixing hole therein. The fixing hole has an opening at a top free end of the supporting post. The fixing hole includes a first section adjacent to the opening, a second section far from the opening and spaced from the first section, and a chamfer section between the first section and the second section. The first section has a diameter larger than that of the second section.
