The toggle component can be used to limit the support rod 2 through the contact of the balancing component, and then the support rod 2 is brought into contact with the uneven ground to adjust the angle. After ensuring that the base 1 is in a horizontal state, the angle of the support rod 2 is limited, and the horizontal position of the base 1 can be fixed, which can be suitable for different uneven grounds to keep the base 1 in a horizontal state. The telescopic frame 4 and the measuring frame 5 are arranged. The telescopic frame 4 can be used to adjust the height of the measuring frame 5, which is convenient for measuring engineering dimensions of different heights and improves the practicability of the device. A hydraulic device is arranged in the telescopic frame 4 to ensure that the telescopic frame 4 can normally adjust the height of the measuring frame 5. The degree can be adjusted; the folding ruler 25 and the driving component can be driven by the driving component to unfold the folding ruler 25 to be in the same straight line when practical; then the folding ruler 25 is used to measure the columnar object; a scale is provided on the upper end of the folding ruler 25 for easy reading of data; the rotating plate 6 can be used to cover the gap of the protective shell 7 to protect the internal structure; the protective shell 7 can be disassembled to repair the internal device; the recording frame 8 can be adjusted to facilitate workers to place the recording table and record data; the rangefinder 9 is provided to facilitate measurement of the straight-line distance; and the rangefinder 9 is detachable for easy use.
