Description

Technical Field

[0001] The utility model relates to the technical field of steel bar installation detection in construction engineering, and more particularly to a telescopic measuring ruler used for steel bar installation in construction engineering. Background Art

[0002] Rebar is a very important material in construction projects. During the installation of rebar, detection tools are needed to detect the spacing of the rebar. However, the position of the vernier of commonly used detection tools is not easy to adjust during use, and its length and width are large, which makes it inconvenient to carry.

[0003] For example, announcement number CN220489882U discloses a telescopic gauge for steel bar installation in construction projects, which includes a mounting frame and is characterized in that it also includes: a handle tube arranged in the middle of the right surface of the mounting frame; and a detection mechanism arranged on the mounting frame.
