Description

Technical Field

[0001] The utility model relates to the technical field of blade repair equipment development, in particular to a knife edge sharpener. Background Art

[0002] At present, most of the commonly used knife sharpening tools are whetstones, whetstones and grinding wheels. The use of these knife sharpening tools to sharpen knives is still effective, but the technical difficulty is relatively large and difficult to master. If you don't master it well, the blunt knife will be sharpened even duller or the blade will be rolled, making the tool scrapped. Electric grinding wheel sharpening has certain risks. In short, using the above knife sharpening tools to sharpen knives is time-consuming and laborious, and the smoothness of the blade of the sharpened tool is poor, which seriously affects the use effect of the tool. It is necessary to develop a knife blade repair tool that is easy to use and control. Utility Model Content

[0003] The purpose of the utility model is to overcome the above-mentioned problems and provide a tool that can realize micro-cutting of the mirror arc of the tool, can effectively prevent the tool blade from creeping or jumping during the repair cutting of the workpiece, and can make the tool blade present a mirror effect after the workpiece is repaired.

[0004] The purpose of the utility model is achieved by the following technical scheme: a tool cutting tool, including a handle, a cutting blade body, the cutting blade body is cylindrical, a beveled blade head is arranged at the front end of the cutting blade body, the blade of the beveled blade head is elliptical, and the beveled surface of the beveled blade head is a mirror surface.

[0005] As a preferred solution of the utility model, an angle a is formed between the beveled surface and the blade body, and the angle a is 19-21 degrees, so that the blade holder is more convenient to push when in use.

[0006] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0007] The utility model has the advantages of simple structure, convenient operation and easy mastery. Through the cooperation of the elliptical blade and the mirror-like beveled surface, not only can the mirror-like arc micro-cutting of the workpiece be achieved, but also the tool cutting device can be effectively prevented from creeping or jumping during the blade repair cutting of the workpiece, so that the blade of the workpiece can be quickly repaired, ensuring the micro-cutting effect of the workpiece, and effectively ensuring the flatness of the blade of the workpiece, so that the workpiece repaired by the tool cutting device of the utility model is sharper, and the blade surface of the workpiece can form a mirror surface. The utility model can be widely used in the blade repair of various workpieces. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The present invention will be further described in detail below in conjunction with specific embodiments, but the implementation methods of the present invention are not limited thereto.

[0014] Example

[0015] like Figure 1~Figure 3 As shown, the blade cutting device in this embodiment includes a handle 1 and a blade cutting body 2. Specifically, the blade cutting body 2 and the handle 1 are fixedly connected. In actual use, the blade cutting body 2 and the handle 1 can also be set as a separate structure. Figure 2 and Figure 3 As shown, in order to facilitate the insertion of the blade body 2 and the handle 1, a rectangular connecting arm 5 is provided on the insertion end of the blade body 2 and the handle 1. Figure 3 As shown, a rectangular plug-in hole 6 matching with a rectangular connecting arm 6 is provided at the front end of the handle 1 .

[0016] The blade body 2 is cylindrical. A bevel blade head 3 is provided at the front end of the blade body 2. The bevel blade head 3 is a blade head with a bevel formed by cutting the blade body 2. The blade of the bevel blade head 3 is elliptical. The beveled surface 4 of the beveled surface head 3 is a mirror surface, that is, the surface smoothness of the beveled surface 4 of the beveled surface head 3 is the same as the smoothness of the mirror surface.

[0017] like Figure 3 As shown, an angle a is formed between the chamfered surface 4 and the blade body 2, and the angle a is actually the chamfering angle of the chamfered surface 4, that is, the cutting angle of the chamfered surface of the chamfered blade head 3. Specifically, the angle a is 19-21°, which can be specifically set according to the actual use situation. In this embodiment, the angle a is preferably set to 20°, so that the blade starter is pushed more smoothly and more convenient to use.

[0018] When used specifically, the working mode of the tool blade starter is based on the working principle of mirror arc micro-cutting. When the chamfered surface 4 of the bevel blade head 3 is in close contact with the horizontal plane of the blade of the workpiece, and the elliptical blade of the bevel blade head 3 is in close contact with the blade of the workpiece, the blade starter body 2 is pushed horizontally by the handle 1, so that the bevel blade head 3 moves horizontally along the blade of the workpiece, and the bevel blade head 3 and the workpiece form a relative motion, and arc micro-cutting is formed, that is, micro-cutting of the blunt body of the workpiece. After several or more micro-cuttings, the blunt body part of the blade can be removed, the sharp body structure of the blade is restored, and the blade of the workpiece presents a mirror surface. At the same time, the elliptical blade design of the bevel cutter head 3 can effectively prevent the tool blade starter from crawling or jumping during micro-cutting, ensuring the formation of a mirror blade by micro-cutting of the workpiece and improving the accuracy of blade repair. The utility model can be widely used in the repair of blades of various tools, such as for the mirror formation of surgical blades, etc.

[0019] As described above, the utility model can be well implemented.
