Abstract
Description
Technical Field

[0002] As a portable measuring instrument for measuring spatial distances, laser rangefinders are widely used in application fields such as construction surveying, real estate surveying and mapping, and house decoration. In fields such as house decoration, laser rangefinders are often used to measure house areas, spatial distances, house volumes, etc., and laser line projectors are used to assist in meeting the construction requirements of horizontality and verticality (such as tiling, staircase construction, etc.). When distance measurement of curved objects is required, a roller-type curved surface rangefinder is also used.
[0003] Existing laser rangefinders either only have the function of laser ranging, or form a rangefinder with two-in-one functions by adding a horizontal line projection module or a roller ranging module, thereby reducing the measuring instruments to be carried. However, there is currently no laser rangefinder that integrates the three functions of curved surface ranging, laser ranging, and laser line projection. Content of the Utility Model
