A circular tube 314 is fixedly connected to the middle of the channel steel frame 310. Openings are formed on the surface of the channel steel frame 310. There are four mounting holes 317 distributed at the corners. Each mounting hole 317 is provided with a mounting piece 320 above it. The surface of the mounting piece 320 is provided with a piece hole 321. The mounting holes 317 and the piece holes 321 can be fixedly connected by screws.
