The leveling rod is a staff used for leveling measurement and is made of high-quality wood or glass fiber reinforced plastic, aluminum alloy and other materials. The commonly used leveling rod comprises a tower ruler, a folding ruler and a double-sided leveling rod. Leveling, also known as "geometric leveling", is a method of measuring the difference in height between two points on the ground using a level gauge and a leveling rod. A level is arranged between two points on the ground, a leveling staff erected on the two points is observed, and the height difference between the two points is calculated according to the reading on the staff. The elevation of each point is typically determined from station to station along a selected leveling route, starting from the leveling origin or any known elevation point. Because the leveling planes with different elevations are not parallel, the height difference between two points measured along different routes is different, so when the national leveling result is collated, necessary correction is carried out according to the adopted normal height system to obtain the correct elevation.

However, in the process of measuring by using the leveling rod, one person needs to hold the tower staff by hand, and the other person needs to read, but the staff often cannot make certain difficulty in measurement in the time of arriving at a construction period, and the vertical arrangement of the tower staff cannot be ensured in the process of righting the tower staff by people, so that the accuracy of reading cannot be ensured; and the support equipment can not be dismantled for during the transport, very inconvenient, influence surveyor's normal work.
