Safety art knife

Abstract

The invention belongs to the technical field of an art knife and particularly relates to a safety art knife. The safety art knife comprises a knife pouch, a blade, a blade pushing button and a knife folding device. According to the safety art knife, when a knife point is blunt in a using process and needs to be broken off, the front end of the knife point to be broken off is aligned at the front end of a knife breaking structure, at the moment, the knife point part is exposed, then the knife folding device at the rear end of the art knife is dismounted, and the knife breaking structure is clamped by a knife clamping seam on the knife folding device; and then the knife folding device is broken off forcefully, a section of blade needing to be broken off is broken off, and the blade which isbroken off is located in the knife breaking structure and cannot flying out to hurt people. In the using process, if the pushing-out length of the blade exceeds a half of length of the whole new blade, after the blade drops on the ground carelessly, the blade swings under stress and a limit strip can be driven to remove limitation to a triangular clamp block, and the blade can slide relative to the knife pouch and is prevented from being broken and flying out to hurt people.

Description

technical field [0001] The invention belongs to the field of utility knife technology, and in particular relates to a safety utility knife. Background technique [0002] During the use of the utility knife, after the tip of the utility knife becomes blunt, you need to break off the blunt section, and then use a new section; in the process of breaking off, first expose the section of the knife tip that needs to be broken off, After that, remove the folding knife at the back end of the utility knife, and clamp the tip of the knife that needs to be broken through the clamping slit on the folding knife; Break off. [0003] But in actual use, there are the following problems: [0004] First, when breaking the blade with a folding knife, because the tip of the knife that needs to be broken is not clamped, the tip of the knife is easy to fly out and hurt people during the breaking process. [0005] Second, some people don’t know that there is a special folder on the utility knif...

AI Technical Summary

Problems solved by technology

[0004] First, when breaking the blade with a folding knife, the tip of the knife that needs to be broken is not clamped, and the tip of the knife is easy to fly out and hurt people during the breaking process.

[0005] Second, some people don’t know that there is a special folder on the utility knife. When they need to break the blade, they insert the tip of the knife directly into other gaps to break it off; Find other gaps to break off, but this operation can easily cause the tip of the knife to fly out and hurt people

[0006] In addition, when using the utility knife, the utility knife may fall. If most of the blades of the utility knife are on the outside of the knife case, when the utility knife falls on the bottom surface, the protruding end of the knife case is prone to knots and The break between the joints, in the process of breaking, causing the blade to fly out and hurt people

[0007] The invention designs a safety utility knife to solve the problem that the tip of the knife flies out and hurts people
