The fixed ring 6 is located above the rotating tube 4 , and two fixed rings 6 can also be connected on a column, and the two fixed rings 6 are located above the two rotating tubes 4 respectively. A positioning rod 7 is worn in the fixed ring 6, and a rubber sleeve is set on the positioning rod 7, thereby preventing the positioning rod 7 from moving arbitrarily in the fixed ring 6. The upper surface of the rotating tube 4 is provided with several uniformly distributed first positioning grooves, and the end of the positioning rod 7 is inserted into the first positioning grooves, thereby realizing the positioning of the diagonal brace 8 .
