The first turning tray is provided with a plurality of notches in the circumference. Each notch has a catching section properly provided for the pressing hook with a fixing portion and an inserting portion formed on one end of a spear to be fixed in. The other end of the spear, i.e. spearhead, can penetrate through a hole in the second turning tray in order to be secured to the roasting jack. When the fixing portion of the pressing hook of the spear being slightly turned upward, the pressing hook will be separated from the catching section so as to make the spear be separated from the notch of the first turning tray.
