[0002] Cutting tools are tools used for cutting in mechanical manufacturing. Most of the tools are machine-made, but there are also hand-made ones. Since the tools used in mechanical manufacturing are basically used to cut metal materials, the term "tool" is generally understood as metal cutting tools. The structure of various tools consists of a clamping part and a working part. The clamping part and working part of the integral structure tool are made on the tool body, and the working part (teeth or blade) of the toothed structure tool is embedded in the tool body. The clamping part of the tool is divided into two types: with holes and with handles. The hole tool is mounted on the spindle or spindle of the machine tool by the inner hole, and the torsional torque is transmitted by the axial key or the end face key, such as cylindrical milling cutters, sleeve face milling cutters, etc. The cutting tool is subjected to greater force during the processing and is easy to break and fly out, which poses a safety hazard and affects the safety of the operator's operation and processing.

[0003] Existing cutting tools cannot conveniently wrap and protect the cutting tools during operation. The cutting tools are prone to loosening, causing the cutting tools to break and fly out, which can easily cause injury to the operator. It is also inconvenient for the operator to disassemble the tool head structure for inspection and replacement. Therefore, technical personnel in this field provide a cutting tool with an anti-flying structure to solve the problems raised in the above background technology. Utility Model Content
