螺母 1 与调节螺母 2 来调节剪线电磁铁行程，通过调节电磁铁行程满足上述调节要
求，剪线电磁铁标准行程为 20mm（图 3）。When adjusting the cutter, make the needle
of the sewing machine be in the upper stop point and turn off the electric control to
perform manual debugging. The hand-pushing cutter electromagnet moves to the left (Fig.
1) Move the knife to the left (head position) to the left,, fixed knife under the plane and
