The vertical rod 11 passes through the space formed by the two adjustment plates 331 from the short side to the long side of the adjustment plate 331 and is connected to the two adjustment plates 331; preferably, the inclination degree of the diagonal support rod 31 is adapted to the hypotenuse of the adjustment plate 331, and the hypotenuse of the adjustment plate 331 is connected to the diagonal support rod 31 by bolts, and each diagonal support rod 31 can be connected to the adjustment plate 331 with two bolts; that is, the two diagonal support rods 31 are clamped between the two adjustment plates 331 and fixed to the adjustment plates 331 by bolts; the lower end of the vertical rod passes through the space between the two adjustment plates 331 from top to bottom, and can then be fixed to the adjustment plate 331 by bolts.
