Background technique

Knives are tools used for cutting in mechanical manufacturing, also known as cutting tools. The vast majority of knives are machine-used, but there are also hand-used ones. Since the tools used in mechanical manufacturing are basically used to cut metal materials, the term "tool" is generally understood as a metal cutting tool. The knives used for cutting wood are called woodworking knives. There is also a type of tool specially used for geological prospecting, well drilling, and mine drilling, called mining tools.

Existing tools need to be inspected after they are produced. In order to observe the production of the tool surface, a magnifying glass is generally used to enlarge the part of the tool to be inspected, but the existing tools are generally held in one hand and the other is held. The magnifying glass observes the tool, which makes it very inconvenient to observe, and it is inconvenient to adjust the height of the magnifying glass when observing the tool through a magnifying glass. Therefore, in order to solve this series of problems, we propose a detection tool The square tube magnifying glass solves the problem.
