The distance meter has smaller volume and is easy to carry.

Description

technical field [0001] The invention provides a range finder, and specifically relates to the field of optical instruments. Background technique [0002] The widely used range finder, that is, the electronic total station (Electronic Total Station) is a high-tech measuring instrument integrating light, machinery and electricity. , horizontal distance), and height difference measurement functions in one surveying and mapping instrument system. When the range finder is used, it is often necessary to carry the range finder with you due to measurement needs, but the existing range finder is quite inconvenient to carry, and the legs of the range finder are relatively large, which is the main reason for the inconvenience. [0003] Patent total station (application number CN201620283359.9), the invention discloses a total station and its use method. The connecting screw used to connect the body of the total station, the connecting screw includes a rotating part and a connecting p...
