The infrared rays hit the reflective object and are reflected back and received by the infrared rangefinder body 25. Then, the distance can be calculated according to the time from the emission to the reception of the infrared rays and the propagation speed of the infrared rays. The infrared rangefinder body 25 is fixed on one of the trees to be measured and aimed at another tree to be measured. The operation thereof can be controlled to measure the distance between the trees, thereby improving the measurement efficiency. The infrared rangefinder body 25 is indirectly rotatably connected to the positioning frame 21, and the operator can adjust the infrared rangefinder body 25 to a horizontal state to improve the measurement accuracy. After the infrared rangefinder body 25 is rotated to a certain angle, it is positioned by the friction between the rubber friction limit pad 236 and the inner wall of the positioning frame 21.
