Abstract
Description

[0001] The utility model belongs to the technical field of municipal greening measurement, and in particular relates to a multifunctional measuring instrument for the diameter at breast height, height and crown width of trees. Background Art
[0002] Currently, the breast diameter of trees is mainly measured with a breast diameter ruler. The breast diameter is calculated by measuring the circumference of the tree and dividing it by 3.14. When measuring the trunk height and total height, a tape measure is generally used. Trees and shrubs are usually several times taller than a person, so acceptance before planting is relatively easy. However, trees are usually taller after planting, so it is more difficult to measure the height and crown width of already planted trees. The second acceptance and re-inspection usually requires the cooperation of multiple people, and multiple tools are required. Measuring the height and crown width during acceptance is even more difficult, and requires the cooperation of multiple people. Utility Model Content
