Description

Sheath sharpening structure

The present invention relates to a sheath sharpening structure, in particular, a protective sleeve structure for covering a tool blade edge portion, and the protective sleeve is provided with a sharpener for grinding the passivation portion of the cutting edge in the future. Restore sharp.

Press, various types of knives, such as kitchen knives, scissors, fruit knives, gardening shears, etc., the metal blade part of the tool, after frequent use, with the accumulation of time and use, the blade part will gradually be used Wear and passivation. In order to restore the sharp edge of the tool, you must use the sharpening stone. The sharpening stone can be used to sharpen the cutting edge of the tool to a sharp state. The general sharpening stone is bulky and heavy. Only the tool can be used to grind the whetstone. Therefore, it is known that it is inconvenient to use, and it is impossible to effectively grind various types of tools. It is produced by a compact knife sharpener on the market.

Please refer to the Republic of China Patent No. M257922 "Knife Sharpener", which consists of a sharpening table, a grinding wheel and a shroud. The shroud is provided with a knife window, and the knife window is opposite to the grinding wheel to sharpen the knife. At least one set of grinding wheels is arranged on one side of the table; wherein the grinding wheel is arranged in an oblique direction, so that the blade is placed behind the grinding wheel to make the blade of the double-sided blade of the blade contact the grinding surface of the grinding wheel, and the blade is actuated to produce a sharpening effect. .

The aforementioned creation is a conventional knife sharpener structure having two corresponding cutters The grinding wheel of the knife face touches the surface of the tool to be ground on the surface of the grinding wheel, and pulls the tool back and forth to perform the sharpening operation; however, the conventional sharpening device is too large, which is not conducive to carrying and use, and the general person is working outside. It does not carry an overly heavy knife sharpener, and it is difficult to repair it through the sharpener structure immediately after the tool wears.

In view of the shortcomings of the portable sharpeners, the creator has been engaged in the manufacturing development and design experience of related products for many years. In view of the above-mentioned shortcomings as the goal to be overcome, the design and careful evaluation are introduced. The sheath sharpening structure is provided for covering the protective edge of the tool blade, and the protective sleeve is provided with a sharpener for the grinding edge of the passivation part of the cutting edge to be sharp and sharp, and has the advantages of convenience and portability.

The present invention relates to a sheath sharpening structure, which is a protective cover structure for covering a tool blade edge portion, and the protective sleeve is provided with a sharpener for sharpening the grinding pin of the passivation portion of the cutting edge in the future.

In order to achieve the above-mentioned creative purpose, the present invention "sheath sharpening structure" includes a protective cover main body having a setting mouth for a tool blade to be worn, and the protective cover main body is disposed on the surface side. There is a whetstone; thus, when the tool is stored, the main system of the protective sleeve is placed on the blade edge of the tool to achieve the protection of the tool edge and to avoid accidental injury to the user. When the blade is passivated, it can pass through the protective cover body. The whetstone grinding pin is used to restore the sharpness of the blade, and the protective cover body is carried by the tool blade when not in use, and has the characteristics of convenient use.

The sharpening stone is disposed at a position on the end side of the protective cover main body.

The protective cover body has a stress groove formed on each of the two side surfaces of the one end of the setting mouth, and the two Each of the stress grooves is formed with a positioning arc groove on the inner surface side.

According to the above-mentioned creation content, the creation of the sheath-grinding structure of the present invention has the dual functions of protection and grinding of the tool blade, and the creation can facilitate the operator to wear out when the construction is outside, compared with the conventional tool protection sleeve. Under the condition of the tool blade, the blade can be repaired by the additional whetstone; therefore, the novel can be said to be a practical and progressive creation, which is worthy of promotion by the industry and is publicized to the public.

The fourth picture is a schematic diagram of the implementation of the grinding operation of the cutting pliers through the sharpening stone.

The present invention relates to a sheath sharpening structure, which is a protective sleeve structure for covering a blade edge of a tool, and the protective sleeve is provided with a sharpener for sharpening the grinding point of the passivation part of the cutting edge in the future. Referring to the first to fourth figures, the present invention "sheath sharpening structure" includes a protective cover main body 1 having a setting opening 11 for a tool blade to be worn, and The protective cover main body 1 is provided with a whetstone 12 on one side of the surface; thus, when the tool is stored, the protective cover main body 1 is sleeved on the blade edge portion to achieve the protection of the tool blade and the effect of avoiding accidental injury to the user. When the blade is passivated, the sharpening of the blade can be restored through the grinding stone 12 on the protective cover main body 1, and the protective cover main body 1 is carried on the tool blade when not in use, and has the characteristics of convenient use. .

Further, the whetstone 12 is disposed at the end side of the protective cover main body 1; thus, the overall length of the protective cover main body 1 is used as a handle for the user to grasp and perform the grinding operation.

Further, the protective sleeve main body 1 is formed with a stress groove 13 on each of the two side surfaces of the one end of the installation opening 11, and the two stress grooves 13 are respectively formed with positioning arc grooves 131 on the inner surface side; thus, the positioning arc groove 131 When the protective cover body is mounted on the cutter-type cutter, the deformation is assisted by the deformation of the stress groove 13, and the elastic buckle is attached to the pivot portion of the cutter, so that the protective sleeve body 1 and the cutter can have a pseudo positioning. The disadvantage of the cover body 1 being easily dropped is avoided.

According to the above-mentioned creation content, the creation of the sheath-grinding structure of the present invention has the dual functions of protection and grinding of the tool blade, and the creation can facilitate the operator to wear out when the construction is outside, compared with the conventional tool protection sleeve. In the case of the tool blade, the blade is repaired by the additional whetstone 12.

The above description is only for explaining the preferred embodiment of the novel creation, and is not intended to impose any form limitation on the creation, so that all the creations in the same creative spirit are related to the creation of the novel. Any modification or change, which is otherwise achievable and has the same effect, should still be included in the scope of this new creative intent.

In summary, the "knife sharpener structure" of this new creation is indeed practical in terms of structural design and practical use, and the disclosed structural creation is also an unprecedented innovative structure, so it has "newness" Sexuality should be undoubtedly considered, and this new creation can be more effective than the conventional structure, so it is also "progressive", which fully complies with the provisions of the new patent application of the Chinese Patent Law. Patent application, I hope that the bureau can grant the patent right in this case as soon as possible.
