Hand-held sharpener structure

This creation is about a hand-held sharpener structure. In detail, it is a sharpener structure with a coarse grinding section and a fine grinding section. Through the combination of the coarse grinding section and the fine grinding section, the passivating cutter can be used. Quickly restore sharpness.

According to the knives, the knives are widely used in today's society, and are often used in cooking, gardening, processing, etc. After a long period of use, the sharp side of the blade will naturally be worn and the passivation will occur. If you continue to cut and cut after passivation, it will be difficult to cut the material smoothly. Therefore, it is necessary to grind the blade to restore its sharpness. Generally, the sharpening stone is used to sharpen the tool. However, the traditional one-piece whetstone is quite cumbersome and not easy to collect, and there are some special-shaped knives whose blade is not suitable for the use of the general long-brick whetstone. Therefore, the market is sold with a lighter hand-held type. knife sharpener.

Referring to the first figure, it is a conventional hand-held sharpener structure, which comprises a handle 3 and a working head 4, and a grinding block 41 is arranged on the working head 4 side, the operator Simply holding the grip 3 and pressing the sharpening block 41 against the blade edge of the tool and rubbing back and forth along the blade extension area can restore the passivated tool back sharp.

The aforementioned creative department is a conventional hand-held sharpener, which has the characteristics of light weight and easy operation; however, there are still some imperfect parts in its application, because the conventional hand-held sharpener structure is only With a single sharpening stone, there is only one specification for the abrasive particles of the sharpening stone. When the applied abrasive particles are too thick, the tool cannot be ground to a more sharp degree, and when the abrasive particles are too fine, it is applied. When the more severe tool is passivated, it takes more time to sharpen the tool.

In view of this, the creator has been engaged in the development of related industries for many years, in-depth discussion on the problems faced by the existing sharpeners, and actively seeks solutions. After long-term research and development, he has finally succeeded in creating The utility model relates to a hand-held sharpener structure, which is a sharpener structure with a coarse grinding section and a fine grinding section. Through the combination of the coarse grinding section and the fine grinding section, the passivated cutter can be quickly restored sharply.

This creation is about a hand-held sharpener structure, which is a sharpener structure with a coarse grinding section and a fine grinding section. Through the combination of the coarse grinding section and the fine grinding section, the passivated cutter can be quickly restored sharply. .

In order to achieve the foregoing creative purpose, the hand-held sharpener structure comprises a handle and a working head, and a working blade is provided with a first grinding block on one side thereof, and the handle has a forming body integrally formed with the working head. a main body segment, and a tail cover segment that is detached from the main body segment, the handle body is formed with a receiving opening on the radial surface of the main body segment opposite to the working end end, and the tail cover segment is provided with a plugged into the receiving opening The second grinding block, the first grinding block has a lower friction coefficient than the second grinding block; thus, the operator has to hold the grip with a lower friction coefficient of the first grinding block to perform the first stage of the passivated tool Grinding operation, after the rectification of the blade passivation is more serious, continue to use the second grinding block to perform the second stage grinding operation on the tool, which can sharpen the blade edge more sharply.

The second sharpening block is a flat shaped grinding pin body.

The second sharpening block can also be an elongated grinding pin body.

The tail cover segment is connected to the second sharpening block portion to form a screw surrounding the second sharpening block, and the receiving opening is a threaded notch corresponding to the screw.

It can be seen from the above-mentioned creations that the "hand-held sharpener structure" of the present invention actually retains the basic advantages of being lightweight and easy to operate, and further distinguishes the sharpening block into a different friction coefficient. A grinding block and a second grinding block, the user can directly perform the sharpening operation through the second grinding block with a higher friction coefficient when grinding the tool with less passivation, and the grinding passivation is more serious. When the tool is used, the first grinding block with a lower friction coefficient can be used for the pre-stage grinding operation. Therefore, the novel can be said to be a practical and progressive creation, which is quite worthy of promotion by the industry. Publicized to the public.

This creation is about a hand-held sharpener structure, which is a sharpener structure with a coarse grinding section and a fine grinding section. Through the combination of the coarse grinding section and the fine grinding section, the passivated cutter can be quickly restored sharply. Please refer to the second to fifth figures. The "hand-held sharpener structure" includes a handle 1 and a working head 2; the working head 2 is provided with a first grinding block on one side. 21, the handle 1 has a main body section 11 integrally formed with the working head 2, and a tail cover section 12 which is detached from the main body section 11. The handle 1 is opposite to the end of the working head 2 at the main body section 11 The cover system is formed with a receiving opening 13 which is provided with a second sharpening block 14 inserted into the receiving opening 13 . The first sharpening block 21 has a lower coefficient of friction than the second sharpening block 14 ( The lower the friction coefficient is, the larger the particle is, the more suitable it is to apply to the rough rubbing surface); thus, the operator has to hold the grip 1 with the first sharpening block 21 having a lower friction coefficient to make the passivating tool One-stage grinding operation, after the repairing is completed, the blade is passivated to a more serious part, and then the second grinding block 14 is used to advance the tool.
