A square tube magnifying glass for detecting tools

technical field

The utility model relates to the technical field of tool detection, in particular to a square tube magnifying glass for detecting tools.

Background technique

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

After the existing tool is produced, it needs to be inspected. In order to observe the production situation of the tool surface, a magnifying glass is generally used to magnify the part of the tool to be inspected, but the existing tool is generally held in one hand and the other in the other. The magnifying glass observes the tool, which makes it very inconvenient to observe, and it is not convenient to adjust the height of the magnifying glass when observing the tool through the magnifying glass. Therefore, in order to solve this series of problems, we propose a detection tool. square tube magnifying glass solves the problem.
