传统磨刀机由两端为轴的半园形铁柄来固定金钢石笔进行裁砂轮,呈弧型进行磨刀。天长日久两轴磨损,轴心偏转,砂轮裁砂的半径也不等,刀磨出的沟半径也不等,而两测刃高低不平,影响运动员滑行速度。由于砂轮片越磨越小,必须经常调整金钢石笔铁架,有时还卸下砂轮片调整高低度,费时费力很不方便。便携式微调裁砂轮装置是用多个螺旋来调节金钢石笔的水平位置、垂直高度、半 Traditional knife sharpener from the ends of the shaft of the semi-circular iron handle to fix the diamond pen cutting wheel, was arc-type sharpening. Everlasting two-axis wear and tear, axis deflection, grinding wheel radius of the sand is not equal, the radius of the knife grinding out of the groove is not equal, and the two measuring edge rugged, affecting the athlete taxi speed. As the grinding wheel smaller grinding, you must always adjust the diamond pen holder, and sometimes remove the grinding wheel to adjust the level, time-consuming and laborious inconvenient. Portable fine adjustment cutting wheel device is to use more than one screw to adjust the horizontal position of the diamond pen, vertical height, half
