[0042] Finally, the flexible plate 11 is bent to fit the outer wall of the pouring area. At this time, the cross-bar assembly 12 is driven by the flexible plate 11, and the included angle of the cross-bar assembly 12 changes. After fitting with the outer wall of the pouring area, the included angle of the cross-bar assembly 12 is fixed, and the bent part of the flexible plate 11 is restricted by the included angle of the cross-bar assembly 12, so that the bending angle of the flexible plate 11 can be fixed.
