Then, depending on the latitude of the area where the fixed plate 19 is located, which one of the ends of the groove on the fixed plate 19 is aligned with the corresponding one of the ends of the side plate 15 is selected, and the screw 20 is passed inward from the outside of the fixed plate 19 through the fixed plate 19 and the side plate 15 to clamp the pitching block 13.

When the sensors 7 and 8 detect a zero signal, it is indicated that the red warp beam or the declination beam has returned to the original position.
