[0002] In the measurement field, API laser tracker is as an important measuring instrument, and the leveling effect of its tripod directly affects the accuracy and efficiency of measurement. However, there are significant problems with the API laser tracker tripod currently, and the adjustment range of the three leveling bolts at its foot is small. When the ground where the instrument is set up is slightly uneven, even if the adjustment bolts at the foot of the tripod are adjusted to the limit position, the instrument often cannot be adjusted to the horizontal measurement state. This severely limits the selection range of the instrument's set-up location and brings many inconveniences to actual measurement work.

[0003] Although there are some specially-made tripods currently, such as "laser tracker tripod with high stability", "tripod" and "laser tracker arbitrary inclination posture measurement device", they can solve the problem of instrument leveling on uneven ground to some extent. However, these solutions generally require the production of special tripods, which not only requires a large amount of time and capital investment for design and manufacturing, but also the universality of special tripods is often poor, making it difficult to flexibly reuse when the measurement scene changes, increasing the cost and complexity of measurement work. Therefore, there is an urgent need for an economic, practical and convenient solution to expand the leveling range of the API laser tracker tripod. UTILITY MODEL CONTENT
