Description

Technical Field

[0001] The utility model relates to the technical field of surveying and mapping tools, in particular to a positioning device for a surveying and mapping instrument. Background Art

[0002] A surveying instrument is an instrument designed and manufactured for surveying and mapping operations, and performs data collection, processing, and output operations. It is often used in the planning, design, construction, and management stages of engineering construction, and is used for various orientation, distance, height, mapping, and photogrammetry required for surveying work. During the surveying and mapping process, the surveying instrument needs to be positioned and its height, orientation, and angle need to be adjusted. When adjusting, the operator needs to adjust the tripod or quadripod supporting the surveying instrument. When the staff operates the instrument, they will use some small tools, such as pens and notebooks for surveying and mapping. It is inconvenient to hold the tools when operating the instrument, and the tools are generally placed on the ground. Since the instrument bracket has a certain height, the staff needs to bend back and forth to take and put the tools, which is easy to cause backache and inconvenience. At the same time, when the staff stores the surveying and mapping instrument, in order to limit the legs, they generally use binding straps to tie the legs, which is inconvenient to tie.

[0003] Therefore, a positioning device for a surveying and mapping instrument is needed which is convenient for accessing tools, storing and operating. Utility Model Content
