Technical Field

[0001] This utility model relates to the field of household knife technology, and in particular to a household knife. Background Technology

[0002] In daily life, especially in rural households, knives are indispensable tools, including kitchen knives and fruit knives. Commonly used knives often have limited functionality, increasing the cost of use. As consumers become more discerning, they seek tools with multiple functions for a single price. Therefore, current technology combines knives with serrated edges, bottle openers, and other structural elements to achieve a more practical and cost-effective solution.

[0003] However, products combining knives and saw teeth have not sold well in the current market, mainly because they are inconvenient to use and the saw teeth are not sharp enough. Therefore, there is an urgent need for a convenient and practical household knife. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model presents a household knife that features serrations and a multi-functional wrench on the blade, making it more convenient to use. The serrations have been improved for sharper edges and a better user experience, allowing it to saw through branches, plastic, and bones. Furthermore, the multi-functional wrench on the blade enables it to be used with various types of nuts, making it even more convenient for home use.

[0005] Specifically, this utility model provides a household knife, including a knife body and a handle mounted on the knife body. The back of the knife body is provided with serrations, all of which are single-edged, and the cutting edges of two adjacent serrations are arranged opposite each other.

[0006] In a further optimization of the technical solution of this utility model, the saw teeth include large saw teeth and small saw teeth, and all the large saw teeth and the small saw teeth are arranged at intervals.

[0007] In a further optimization of the technical solution of this utility model, the saw teeth are triangular and / or quadrilateral structures.

[0008] A further optimization of the technical solution of this utility model is that the blade body is also provided with a multi-functional wrench hole.

[0009] In a further optimization of the technical solution of this utility model, the multi-functional wrench hole is located on the side of the blade body near the back of the blade and away from the handle.

[0010] In a further optimization of the technical solution of this utility model, a striking blade is also provided on the blade body. The striking blade is disposed on the back of the blade and arranged side by side with the serrations. The striking blade is located at the end of the back of the blade away from the handle.

[0011] A further optimization of the technical solution of this utility model is that the saw tooth near the end of the handle is higher than all other saw teeth, and no saw blade is formed on the saw tooth.

[0012] A further optimization of the technical solution of this utility model includes a saw sleeve, which is engaged on the saw teeth corresponding to the back of the blade.

[0013] A further optimization of the technical solution of this utility model is that the blade body is provided with a groove or protrusion corresponding to the saw sleeve, so as to prevent the saw sleeve from falling off.

[0014] Compared with the prior art, the advantages of this utility model are as follows: By setting single-sided serrations on the back of the blade and designing the structure of the serrations and blade, the sharpness of the serrations can be increased. Combined with a multi-functional wrench, the serrations become more practical. When used at home, people can use the serrations to saw bones or some items that are difficult to cut.

[0022] The following will be combined with the appendix Figure 1-4 The present invention will be further described below.

[0023] Knives are essential household tools, commonly used for cutting vegetables. However, wrenches and saws are not commonly found in ordinary households. While saws or wrenches may be used occasionally in daily life, buying a separate tool results in low usage frequency and low cost-effectiveness. To improve the cost-effectiveness of knives and attract more consumers to choose the applicant's knives based on practicality, this application presents a household knife, specifically comprising a blade body 1 and a handle 2 mounted on the blade body 1. The back of the blade body 1 is provided with serrations 5. All serrations 5 are single-edged, and the cutting edges of adjacent serrations are arranged opposite each other. This spatial offset between adjacent serrations increases the lateral span of the saw, reduces the difficulty of cutting the kerf, makes the overall blade sharper, and provides a better sawing experience. Figure 2 and Figure 3 As shown, the saw teeth 5 are configured as large saw teeth 51 and small saw teeth 52, and all the large saw teeth 51 and small saw teeth 52 are spaced apart from each other. With the relative arrangement of the saw blades of two adjacent saw teeth, the individual saw teeth can be more targeted when sawing things, and it is easier to bring out the sawdust.

[0024] In this preferred embodiment, the saw teeth are triangular and / or quadrilateral in structure, with a quadrilateral structure being preferred, such as... Figure 3 As shown, the saw teeth 5 can be configured as a quadrilateral structure, or a combination of a triangular structure and a quadrilateral structure. When the triangular structure and the quadrilateral structure are combined, the height of the triangular saw teeth is less than the height of the quadrilateral saw teeth, and the triangular and quadrilateral saw teeth are staggered. Preferably, a quadrilateral structure is used. The quadrilateral structure includes a first saw blade 53, a second saw blade 54, and a third saw blade 55. The first saw blade 53 is connected to the third saw blade 55 through the second saw blade 54. This saw blade is used on the saw teeth 5 of a kitchen knife or fruit knife, which can make the saw teeth 5 sharper and more durable.

[0025] To further improve the cost-effectiveness of the household knife of this application, a hexagonal multi-functional wrench 3 hole is also provided on the knife body 1, with two sides extended and multiple protrusions, so that it can match nuts of different sizes, making it more convenient to use, and one wrench can be used as multiple wrenches.

[0026] like Figure 1 As shown, the blade body 1 of this application can be configured as a right-angled trapezoidal structure with a wider end away from the handle 2. The serrations 5 are set on the long inclined side of the trapezoid, increasing the length of the serrations 5. The multi-functional wrench 3 hole is located on the side of the blade body 1 near the back of the blade and away from the handle 2, i.e., located on... Figure 1The upper right corner of the blade does not affect the strength of the blade body 1 and is more convenient to use. Additionally, preferably, a striking blade 4 is also provided on the blade body 1. The striking blade 4 is located on the back of the blade and is arranged side-by-side with the serrations 5. The striking blade 4 is located at the end of the back of the blade away from the handle 2. Combined with the right-angled trapezoidal design of the blade body 1, the front end of the blade body 1 is heavier, resulting in greater force and better performance when using the striking blade 4.

[0027] For safety, the serration 5 near the end of the handle 2 is higher than all other serrations, and this serration has no cutting edge, making it a blunt serration. Because the serration 5 is not frequently used, this application also includes a saw sleeve 7, which is secured to the serration 5 corresponding to the back of the blade. Preferably, the saw sleeve 7 is made of plastic, making it lightweight, and the saw sleeve 7... Figure 4 As shown, its blade slit has an inverted trapezoidal structure, which can clamp the blade body 1 at the entrance side to prevent it from falling off; preferably, the blade body 1 is provided with a groove or protrusion 6 corresponding to the saw sleeve to prevent the saw sleeve 7 from falling off and to increase the clamping force between the saw sleeve 7 and the handle 2.

[0028] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0029] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
