[0002] The tool is an indispensable tool in people's daily life and production process. The tool generally consists of two parts: the tool body and the blade. The tool body is usually made of metal or plastic, providing support for holding and operating the tool. The blade is the cutting part of the tool, usually made of hard materials, such as high-alloy steel, etc., used to achieve cutting processing. When using the tool, by holding the tool body, the tool body drives the blade to contact the object to be cut, and a certain cutting force is applied, so that the part to be cut of the object to be cut is cut or removed to achieve the purpose of processing. From the traditional method of using the tool, we can find that this method still has some disadvantages, such as: the traditional tool, in the process of cutting, because there is no protection mechanism, the tool is easy to accidentally damage the part that should not be cut, thereby causing damage to the object, and there are certain safety hazards. In addition, due to the lack of a limit mechanism, the tool is easy to produce cutting deviation during the cutting process, affecting the cutting accuracy and resulting in unsatisfactory cutting results. Especially in occasions where precise cutting is required, additional trimming of the cutting deviation may be required later. Moreover, since there are no protective parts, operators often need to be more cautious when using tools for cutting, and use human intervention to reduce damage to other structures that should not be cut, which greatly reduces cutting efficiency and further slows down the processing progress. Therefore, designing a tool that can effectively improve the safety, accuracy and efficiency of cutting operations is an urgent problem that the current tool industry needs to solve.
