One end of the second fixing column 10 is fixed to the A second fixed column 10 is fixedly connected, and a pulley 11 is movably connected to the outer surface of the second fixed column 10. The pulley 11 is movably connected to the second fixed column 10 through a bearing. The outer surface of the pulley 11 is fixedly connected to the first damping layer 12. The outer diameter of the pulley 11 is equal to the inner diameter of the first damping layer 12. The outer surface of the second fixed column 10 is fixedly connected to a fixed cover 14. The interior of the fixed cover 14 is fixedly connected to the second damping layer 13. The inner diameter of the fixed cover 14 is equal to the outer diameter of the second damping layer 13.
