这把尺子防滑性极强，是理想的精准切割工具。按住它的中心，底部的防滑面可将尺子紧紧固定在原位；而按住背面时，防滑面则可向其他方向随意滑动。

     This ruler, with its nonslip features, is ideal for precise cutting work. When the center is held down the nonslip feature on the bottom firmly anchors the ruler in place, and when the back side is held the nonslip feature can slide smoothly and move to a new position.
