Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cutting knives, in particular to a cutting knife with high stability and capable of preventing static electricity. Background Art
[0002] A cutting knife is a commonly used tool in industry and life. It is often used to cut paper, leather, plastic sheets or cardboard, etc. A cutting knife usually uses a push-pull block to push the blade forward so that the blade extends from the inside of the knife holder to the outside of the knife holder for cutting. A cutting knife is a frequently used tool in daily life and is often used in cutting paper and other aspects.
[0003] Prior art, such as: CN212590662U a small multi-layer cutting blade, the small multi-layer cutting blade, during use, the upper and lower incisions are unified, eliminating the problem of the incision exceeding the sewing edge and being unusable, the blade tip is designed to be an oblique flat edge, solve the problem of the blade tip breaking when the tool is fatigued, and the end of the handle and the end of the blade tip are on the same center line, which can reduce overcutting to a minimum, the bevel angle of the blade direction when cutting, the blade vibrates up and down, and the blade is in an oblique pulling state, which is more conducive to cutting; after the blade back is narrowed, it is more conducive to the blade to penetrate into the material when cutting, and when entering the material, the blade and the blade back are subjected to bidirectional force, thereby reducing the breakage phenomenon when the tool penetrates the material.
[0004] However, the device still has certain shortcomings during use. The connection between the handle and the blade head is fixed. When the blade head is not in use, it is not easy to store. Exposing it to the outside will not only cause danger, but also the blade head will rust, affecting its use. Since the blade head and the blade rod are integrally formed and the material is conductive metal, static electricity will be generated during use, which not only affects the cutting work, but also reduces the cutting quality. Sawing operation is required during work, and the device does not have this function and needs to replace equipment for operation. At the same time, the device is not easy to carry, which reduces its practicality. In addition, in order to maintain its structural strength, the wrench in the prior art generally adopts metal materials, which will lead to the risk of static electricity when it is working, and in severe cases, it will cause injury to the operator. The current countermeasures mainly use anti-static coating on the metal material, but the coating is easily worn and not durable, which will reduce the anti-static effect. Utility Model Content
