The fitting orifice is fitted with the support rod, the arcuate orifice passes through the fixing mount, the receiving orifice passes through the fixing mount, two clamping hooks of the two locking jaws are clamped on two end portions of an extending plate of a H beam. The controlling member is connected with the fixing mount and swings between a locking position and an unlocking position. The controlling member has a lock bolt and two apertures, and the two inserting bolts are inserted into the two apertures and the receiving orifice so as to limit the controlling member at the locking position.
