Any group of rotating assemblies includes a fulcrum bearing 5, a bearing inner sleeve 6, a bolt 7 and a column 8. The bottom of the column 8 is slidably arranged in the T-shaped slot 2, and the bearing inner sleeve 6 is fixed to the middle of the column 8 by a screw plug on the outer diameter surface. The fulcrum bearing 5 is rotatably connected to the outside of the bearing inner sleeve 6. The bearing inner sleeve 6 is an L-shaped bearing sleeve. Three threaded holes are evenly distributed on the upper outer diameter surface of the bearing inner sleeve 6, and the threaded holes are communicated with the column.
