[0028] By rotating the arc-shaped fixing frame 2 42, the arc-shaped fixing frame 2 42 drives the fixing shell 2 3 to move to the upper surface of the fixing shell 1 2, and then the threaded rod 43 passes through the inner cavity of the arc-shaped fixing frame 1 41 and the arc-shaped fixing frame 2 42, and the threaded rod 43 is fixed inside the arc-shaped fixing frame 1 41 and the arc-shaped fixing frame 2 42 by a nut, so that the fixing shell 1 2 and the fixing shell 2 3 are fixed together.
