Description

Technical Field

[0002] In the field of engineering surveying, lasers, as high-precision measuring tools, directly affect the accuracy and reliability of measurement results due to their performance and stability. However, existing engineering surveying lasers have several problems in practical use. For example, traditional measuring support structures lack structural stability, making them difficult to adapt to complex measurement environments and prone to measurement deviations; some supports lack flexible and precise adjustment functions, failing to meet the needs of different measurement angles and heights; and some lasers are not securely installed and fixed, easily shifting or shaking during measurement, affecting accuracy. Furthermore, unreasonable foot designs make them difficult to maintain stability on uneven ground and prevent quick and effective adjustments based on actual conditions. Therefore, to improve the accuracy and efficiency of engineering surveying, it is necessary to develop an engineering surveying laser that is structurally stable, flexible in adjustment, easy to install, and adaptable to various measurement environments.
