[0011] Further improvement of the above technical solution lies in that the edge frame top corner part of the frame body is covered with a reinforcing plate one.

[0012] Further improvement of the above technical solution lies in that the vertical beam bottom and the frame body lower edge frame connecting part are covered with a reinforcing plate two.

[0013] Further improvement of the above technical solution lies in that the frame body and the vertical beam adopt a hollow square tube, and the horizontal beam and the inclined pull beam adopt an L-shaped bent plate.
