After the pointer 408 points to the specified scale position, loosen the limit card frame 5, so that the damping telescopic rod B501 and the outer spring pop out of the limit card frame 5 and slide into the relative limit card slot 402. If there is a deviation in the position and the cutting disc 407 needs to be adjusted upward, push the scale 401 upward.
