Theodolite is a precision instrument widely used in the field of measurement. It is mainly used for measuring horizontal and vertical angles and is an indispensable tool in many fields such as engineering construction, topographic surveying, and land planning. Its core structure includes a telescope, a horizontal graduated circle, and a vertical graduated circle. The telescope is used for aiming at the target, and its optical system is well - designed to provide a clear and accurate field of view. The horizontal and vertical graduated circles are used for precise angle measurement, and with the help of precise scales and reading devices, high - precision angle measurement can be achieved. Modern theodolites are also equipped with electronic displays, which facilitate the reading of measurement data and greatly improve work efficiency. With high measurement accuracy and strong stability, it can maintain good performance under various complex environmental conditions and provide reliable data support for measurement work.

经纬仪脚架是经纬仪的重要辅助设备，用于支撑和固定经纬仪，确保其在测量过程中的稳定性。它通常由三根可伸缩的支腿组成，支腿的长度可以根据测量场地的地形进行灵活调整。脚架的材质多为坚固的金属合金，具有良好的承重能力和抗变形能力。在脚架的底部装有防滑脚钉，能够在各种地面条件下提供稳定的支撑，防止仪器滑动。同时，脚架还配备有水平调节装置，通过调节脚架的高度和角度，可以快速将经纬仪调整到水平状态，为精确测量创造良好的条件。其设计合理、结构稳固，能够有效保障经纬仪的测量精度和使用寿命。

The theodolite tripod is an important auxiliary device for the theodolite. It is used to support and fix the theodolite to ensure its stability during the measurement process. It is usually composed of three extendable legs, and the length of the legs can be flexibly adjusted according to the terrain of the measurement site. The tripod is mostly made of sturdy metal alloy, which has good load - bearing capacity and anti - deformation ability. Anti - slip foot spikes are installed at the bottom of the tripod, which can provide stable support on various ground conditions and prevent the instrument from slipping. In addition, the tripod is equipped with a leveling device. By adjusting the height and angle of the tripod, the theodolite can be quickly adjusted to a horizontal state, creating good conditions for precise measurement. With a rational design and a sturdy structure, it can effectively ensure the measurement accuracy and service life of the theodolite.
