[0028] As an implementation method in this embodiment, the limiting mechanism: a convex strip 13 is rotatably connected in the inner cavity of the cross beam 12 (beside the fixed strip 14), and the rotating shaft of the convex strip 13 protrudes from the cross beam 12. In order to control the rotation of the convex strip 13, a No. 1 mounting plate 6 and a No. 2 mounting plate 7 are provided on the outer wall of the screen plate 4.
