A bolt is inserted through the first threaded hole. A second threaded hole is defined through a bottom surface of the head and coaxial with the first threaded hole and the passage. A shaft has a lower end inserted in the passage of the neck. A third threaded hole is defined at the lower end and engaged with the bolt.
