Side shear opening height adjustment is realized by changing
the connection length of the side shear drive rod. Loosen the
top wire on the pendulum fork pin, adjust the side of the shear
drive rod connection length, when the drive rod is adjusted long,
the side of the shear opening height increases, and vice versa,
the side of the shear opening height decreases. The maximum
opening height of the side shear is adjusted according to 8mm.
If you change the angle of the pendulum fork installed on the
shaft of the reed, it will also change the opening height of the
side shear.
