[0002] In mines, minerals are often located deep below the surface. The mining of minerals deep below the surface often requires detection after digging inclined holes. Measuring the depth and inclination of the inclined holes after drilling is a necessary and arduous task, so a depth measuring rod is usually required to measure the inclined holes.

By providing a rotatable and movable measuring rod, it is convenient to cooperate with the protractor to measure the depth and slope of the inclined hole.
