Figure 3-4 The lower steel plate 1 is cross-connected with the upper steel plate 2 by inserting into the groove 21. Figure 2 The lower steel plate 1 is provided with a limit group on both sides thereof, and the limit group is composed of two parallel limit convex strips 11. When the lower steel plate 1 is connected to the upper steel plate 2, the upper steel plate 2 is located between the two limit convex strips 11. A base 12 is provided at one end of the lower steel plate 1, and a positioning groove 13 corresponding to the upper steel plate 2 is provided at the other end of the lower steel plate 1. The thickness of the lower steel plate 1 is less than the width of the groove 21.

[0045] Reference Figure 3-4 The fixing member 3 is disposed in the groove 21 and is detachably connected to the upper steel plate 2. When the lower steel plate 1 is connected to the upper steel plate 2, the lower steel plate 1 abuts against the fixing member 3. The telescopic adjustment of the steel pipe is achieved by controlling the position of the fixing member 3 in the groove 21. Specifically, referring to Figure 5 The fixing member 3 includes an abutting plate 31, a connecting plate 32 and a first screw rod 33. At least two connecting plates 32 are arranged at diagonal positions of the abutting plate 31. The connecting plate 32 is provided with a first through hole 32a. The first screw rod 33 can movably pass through the first through hole 32a and the second through hole 22. Figure 6 An opening 41 is axially provided on the reinforcing plate 4, and the shape of the opening 41 is the same as the shape of the lower steel plate 1 and the upper steel plate 2 after being connected. A third through hole 42 is radially penetrated by the reinforcing plate 4, and the second screw rod 5 can movably pass through the third through hole 42 and the second through hole 22.

[0046] Working principle: The upper steel plate 2 and the lower steel plate 1 are removed during transportation. During installation, the reinforcing plate 4 is first inserted into the lower steel plate 1, and then the fixing member 3 is placed in the groove 21 and the upper steel plate 2 is inserted into the lower steel plate 1 along the limiting convex strip 11. After adjusting to the target height, the first screw rod 33 passes through the first through hole 32a and the second through hole 22, and then the reinforcing plate 4 is adjusted so that the upper steel plate 2 and the lower steel plate 1 are simultaneously embedded in the opening 41 and the second screw rod 5 passes through the third through hole 42 and the second through hole 22.
