Description
Technical Field
[0001] The utility model relates to the technical field of scissors, in particular to a labor-saving and safe scissors. Background Technique
[0002] Scissors are tools used to cut materials such as paper, cloth, and hair. They usually consist of two hard blades connected by one or more pivot points to form a lever system. When the two blades move relative to each other, their cutting edges will cut the object due to friction and pressure. The design and manufacture of scissors involve knowledge in multiple aspects such as mechanics, materials science, and ergonomics. There are various types of scissors, commonly including ordinary household scissors, professional scissors (such as cloth-cutting scissors for tailors and hair-cutting scissors for barbers), office scissors, children's scissors, etc. Each type of scissors has its specific uses and design features to meet the needs of different users. When choosing scissors, factors such as their uses, materials, sizes, weights, and whether they conform to ergonomic designs should be considered. High-quality scissors can not only improve work efficiency but also reduce the fatigue of users and ensure operation safety.
[0003] Although existing scissors are widely used, they still have some deficiencies. Scissors are tools that work using the lever principle. When performing some precise cutting work, scissors need to act as a laborious lever to ensure the precision and stability of cutting. When performing some cutting or splitting work, scissors need to act as a labor-saving lever to make the scissors more labor-saving. Existing scissors cannot switch between a labor-saving lever and a laborious lever, resulting in inconvenient use. Moreover, existing scissors do not have safety protection measures and are relatively dangerous. Therefore, a labor-saving and safe scissors is proposed to address the above problems. Content of the Utility Model
