Description

Technical Field

[0001] The utility model relates to the technical field of surveying and mapping instruments, in particular to a surveying and mapping instrument which is convenient for adjusting the surveying and mapping height. Background Art

[0002] In construction and engineering projects, the height of buildings, bridges and other structures needs to be accurately measured. An easily adjustable surveyor can help ensure that the verticality and height of buildings meet design requirements. The design and planning of roads, railways and other transportation infrastructure need to take into account terrain changes and height differences. The height adjustment function of the surveyor can provide critical geographic information in transportation planning. In hydrological studies and water resource management, surveyors can be used to measure the height of water bodies, the slope of river channels and changes in the surface to support water resource planning and management.

[0003] When adjusting the height of an existing surveying instrument, bolts and screw holes are generally used to cooperate with an adjustment frame to move the adjustment frame up and down, thereby adjusting the surveying height of the surveying instrument. However, the precision of the height adjustment is low and high-precision adjustment cannot be performed, which affects the accuracy of the surveying. In addition, after the height of the surveying instrument is adjusted appropriately, there is a lack of relevant locking structure, and the height cannot be fixed in time, which affects the surveying speed.
