[0009] Further, the concentric disc includes a fixed disc and a movable disc. The inner ring of the fixed disc is welded to the bottom of the second circular tube, and the movable disc is sleeved with the outer wall of the second circular tube through the inner ring, and the two form a movable connection.

[0010] Further, the base is formed by welding two square steels in a cross shape. The top end of the intersection part of the two square steels is welded to the bottom end of the first circular tube.

[0011] Further, the base square steel has a size of 20*20*2.5mm and a length of 0.4-0.8m.

[0012] Further, the first circular pipe and the second circular pipe are both galvanized steel pipes, the first circular pipe has a length of 0.2-0.5m and a nominal inner diameter of DN32-DN50, and the second circular pipe has a length of 0.4-0.7m and a nominal inner diameter of DN80-DN125, the length of the second circular pipe is greater than that of the first circular pipe, and the nominal inner diameter of the second circular pipe is greater than that of the first circular pipe.
