The connecting groove 41 is formed on the surface of the adjusting plate 2, and the connecting block 42 is disposed inside the connecting groove 41. The connecting block 42 is connected to the protective block 51.

[0037] The connecting block 42 and the connecting groove 41 are T-shaped. The use of the connecting groove 41 and the connecting block 42 facilitates the connection between the protective block 51 and the adjusting plate 2. The shape of the protective block 51 is adapted to the shape of the adjusting plate 2. Fixing holes adapted to the fixing bolts 7 are opened between the protective block 51, the connecting block 42 and the adjusting plate 2.
