[0024] The inner wall of the slot 5 is movably connected with a limit plug 8, and one end of each of the limit plugs 8 is fixedly connected with a rotation limit cover 9. The lower end of the rotation limit cover 9 contacts the upper surface of the rotation bracket 4, and the rotation limit cover 9 serves to quickly position and install the rotation bracket 4. The inner top wall of the rotation limit cover 9 is fixedly connected with symmetrically distributed arc-shaped stabilizing blocks 10, and one end of the arc-shaped stabilizing blocks 10 penetrates and extends to the interior of the movable groove 6. The outer surfaces of the two arc-shaped stabilizing blocks 10 are in contact with the inner wall of the limit ring 7. The arc-shaped stabilizing blocks 10 cooperate with the limit ring 7 to improve the stability of the rotation bracket 4 during rotation. The inner top wall of the rotation limit cover 9 is fixedly connected with symmetrically distributed arc-shaped elastic sheets 11.

[0025] One end of the arc-shaped elastic sheet 11 passes through and extends to the inside of the movable groove 6. An arc-shaped rotation groove 12 is provided on the outer surface of the arc-shaped elastic sheet 11. The inner walls of the two arc-shaped rotation grooves 12 are in sliding contact with the inner surface of the limit ring 7. The arc-shaped rotation groove 12 is in sliding contact with the limit ring 7 to cooperate with the arc-shaped elastic sheet 11 for positioning and rotation. A bevel 13 is provided at one end of the arc-shaped elastic sheet 11. The bevel 13 facilitates the extrusion and deformation of the arc-shaped elastic sheet 11.
