Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and more specifically, to an external auxiliary tool for chopping with kitchen knives. Background Technology

[0002] As one of the most common and frequently used kitchen knives, the kitchen knife is widely used in households, catering, and food processing industries. In daily use, users often need to use kitchen knives and other kitchen knives to perform various operations such as chopping, cutting, mincing, and slicing. Especially when dealing with harder ingredients (such as dried meat, frozen meat, meat with bones, nuts, etc.), greater pressure needs to be applied to complete the cutting.

[0003] Most existing kitchen knives and other kitchen utensils are made of a single piece of metal, with the handle usually far from the point of contact with food. In actual use, users often have to rely solely on the strength of their wrists and fingers to apply downward pressure, lacking an effective fulcrum. This leads to uneven force application, low efficiency, and can easily cause hand fatigue or even slippage after prolonged use, posing a safety hazard. Furthermore, the handle structure of traditional kitchen knives does not fully consider ergonomic design, resulting in concentrated pressure in certain areas, affecting comfort and operational stability. Especially during high-intensity chopping and slicing operations, the lack of an auxiliary force-bearing structure makes it difficult for users to apply leverage, increasing labor intensity and reducing work efficiency.

[0004] Therefore, there is an urgent need for a kitchen knife auxiliary tool that can effectively improve the chopping and slicing experience, enhance grip comfort and increase force application efficiency, and save effort and provide protection during use. Summary of the Invention

[0005] The present invention aims to solve the technical problems mentioned in the background art by providing an external auxiliary tool for chopping with kitchen knives. By setting a force point that provides stable support near the handle of the kitchen knife, the user can more effectively exert force during chopping by using this fulcrum. At the same time, the tool is fitted onto the back of the kitchen knife and covered with soft material, with a certain grip curvature to improve the operating feel, thereby improving the grip comfort, reducing hand pressure, and achieving easy, efficient, and safe chopping and cutting operations.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an external auxiliary tool for chopping with a kitchen knife, comprising: a front end, the lower end of which is formed with a thumb portion, the top end of which is integrally formed with an arc-shaped middle end, the left end of which is integrally formed with a rear end, the bottom side of which and the right side of which are formed with a knife back groove for embedding into the back of a knife, the left side of which is symmetrically provided with an anti-slip portion and a middle finger portion with an arc-shaped anti-slip surface at both ends, and the left middle end of which is provided with an index finger portion with an arc-shaped anti-slip surface.

[0007] A further preferred embodiment: the longitudinal section of the front end is an arc plate shape with the upper end vertical and the lower end curved outward, the inner side of the upper end of the front end is in close contact with the front side of the kitchen knife, and the front side of the kitchen knife is the side close to the food to be chopped.

[0008] A further preferred embodiment: the middle part is convex upward, and the outer side of the middle part is in close contact with the user's palm.

[0009] A further preferred embodiment: the longitudinal section of the rear end is a plate-shaped structure with vertical top and bottom, a groove on the left side, and a flat right side, and both the rear end and the bottom of the thumb part are provided with rounded corners.

[0010] A further preferred embodiment: the right side of the rear end is in close contact with the rear side of the kitchen knife, and the rear side of the kitchen knife is the side away from the food to be chopped.

[0011] A further preferred embodiment: the blade groove fits tightly with the back of the kitchen knife, and the front end, middle end, and rear end are integrally formed and made of plastic.

[0012] A further preferred embodiment: the outer surfaces of the front end, middle end and rear end are covered with a soft layer.

[0013] A further preferred embodiment: the vertical length of the front end portion is greater than the vertical length of the rear end portion.

[0014] A further preferred embodiment: the index finger portion is for placing the user's index finger, the thumb portion is for placing the user's thumb, and the middle finger portion is for placing the user's middle finger. Beneficial effects

[0015] 1. By placing the front end and thumb near the handle of the kitchen knife, a stable force fulcrum is formed. When the user is chopping, he can use his thumb to hold the fulcrum, forming a leverage effect, which effectively improves the efficiency of downward force application and reduces the burden on the arm, palm and wrist. It is especially suitable for cutting harder ingredients (such as frozen meat, cartilage, dried meat, etc.).

[0016] 2. By setting an index finger section on the middle left side of the tool's rear end, and the middle finger section on the rear left side of the tool's rear end, along with the thumb section on the front thumb section, pressing together and coordinating with the wrist's force, a stable connection is formed between the hand and the knife, preventing slippage or deviation during operation, thereby improving the control precision and safety of the kitchen knife.

[0017] 3. By adopting an upward convex design at the middle end and wrapping it with a soft silicone layer, it conforms to the curve of the palm, distributes grip pressure, avoids excessive local pressure, and is less likely to cause soreness after long-term use, greatly improving the comfort of operation.

[0018] 4. The entire auxiliary tool is integrally molded from the front, middle and rear ends, and is fitted onto the back of the kitchen knife. It fits tightly with the back of the knife through the blade groove, making it easy to install and remove without damaging the original knife structure. It is suitable for a variety of common kitchen knife models and has strong versatility.

[0019] 5. The silicone material covering the outer surface of the auxiliary tool is not only soft and comfortable, but also has good anti-slip properties, which can maintain a stable grip even in wet or oily environments, greatly reducing the risk of accidental injury caused by slipping.

[0020] 6. In summary, this type of external auxiliary tool, which is used in conjunction with kitchen knives for chopping, can effectively improve the chopping and cutting experience, enhance grip comfort, and increase the efficiency of force application, saving effort and providing protection during use.

[0025] The following will refer to the appendix in the embodiments of this utility model. Figures 1-3 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0026] Please see Figure 1-3In this embodiment of the invention, an external auxiliary tool for chopping with a kitchen knife includes: an integrally formed front end portion 1, which serves as the front support structure of the entire auxiliary tool, providing a force-bearing point close to the blade for easy force application, and playing a role in positioning and fixing the overall structure; a thumb portion 101 formed at the lower end of the front end portion 1, providing a clear thumb placement area and stable support for the user's thumb. When downward pressure is applied, the thumb can press against this portion, forming a reverse fulcrum, improving force efficiency, preventing hand slippage or deviation, and enhancing operational safety; an integrally formed curved middle end portion 2 at the top of the front end portion 1, which is the main contact area for the fingers and plays a role in buffering and force transmission during chopping; and an integrally formed rear end portion 3 at the left end of the middle end portion 2. The rear end 3 has an arc-shaped anti-slip surface for the index and middle fingers to contact, and the overall structure is stable. Together with the front end 1, the middle end 2 and the rear end 3, they form a complete grip structure. The bottom side of the middle end 2 and the right side of the rear end 3 are formed with a blade back groove 4. The blade back groove 4 allows the auxiliary tool to be firmly fitted onto the back of the kitchen knife, achieving a tight connection between the tool and the knife, ensuring that it will not loosen during use, and improving the stability and safety of the overall structure. The left side of the rear end 3 has symmetrical anti-slip parts 302 and middle finger parts 303 with arc-shaped anti-slip surfaces at the front and rear ends, respectively. The left side of the rear end 3 has an index finger part 301 with an arc-shaped anti-slip surface in the middle, corresponding to the user's two main fingers (index finger and middle finger), respectively. Combined with the thumb part 101 at the lower end of the front end 1 where the user's thumb is placed, it provides a stable finger support point, enhancing grip strength and stability.

[0027] In this embodiment of the utility model, the longitudinal section of the front end 1 is an arc plate shape with the upper end vertical and the lower end curved outward. The inner side of the upper end of the front end 1 is in close contact with the front side of the kitchen knife. The front side of the kitchen knife is the side closer to the food to be chopped. The inner side of the upper end of the front end 1 is in close contact with the front side of the knife (i.e. the side closer to the food to be chopped), which enhances the fit. The curved design conforms to ergonomics and improves the grip comfort.

[0028] In this embodiment of the utility model, the middle end 2 is convex upward, and the convex structure can naturally fit the palm of the hand to form force support, and the outer side of the middle end 2 is in close contact with the user's palm.

[0029] In this embodiment of the utility model, the longitudinal section of the rear end 3 is a plate-shaped structure with vertical top and bottom, groove on the left side and flat on the right side. The groove structure on the left side of the rear end 3 facilitates the insertion and stable gripping of fingers. Both the rear end 3 and the bottom of the thumb part 101 are provided with rounded corners to avoid scratching or hurting the hand, and also to prevent pressure or discomfort to the fingers.

[0030] In this embodiment of the utility model, the right side of the rear end 3 is closely attached to the rear side of the kitchen knife. The rear side of the kitchen knife is the side away from the food to be chopped. The rear end 3 not only ensures a close fit between the auxiliary tool and the kitchen knife, improving the stability and safety of the overall structure, but also avoids interference with the blade's operating area.

[0031] In this embodiment of the utility model, the back groove 4 fits tightly with the back of the kitchen knife. The back groove 4 is formed on the bottom side of the middle end 2 and the right side of the rear end 3. Its shape matches the back of the kitchen knife and fits tightly. The front end 1, the middle end 2 and the rear end 3 are integrally formed and made of plastic. Plastic has a certain elasticity, which makes it easy to install and disassemble.

[0032] In this embodiment of the invention, the outer surfaces of the front end 1, the middle end 2, and the rear end 3 are covered with a soft layer. The soft layer covers the outer surface of the tool, improving the grip, enhancing the anti-slip effect, preventing slippage caused by hand sweat or oil, relieving hand fatigue caused by prolonged use, dispersing local pressure on the hand, and improving comfort. The soft layer has a certain thickness, is soft but not easily deformed, easy to clean, and heat resistant, making it suitable for use in the kitchen environment. The soft layer can be made of silicone to improve the touch and anti-slip performance.

[0033] In this embodiment of the utility model, the vertical length of the front end 1 is greater than that of the rear end 3, which allows the auxiliary tool to better fit the palm's force application area during use, enhance the stability of the thumb fulcrum, and effectively improve the force application efficiency; at the same time, the longer front end 1 can form a larger contact area with the front side of the kitchen knife, improving the overall structural strength and connection stability, and is especially suitable for high-intensity chopping and cutting operations.

[0034] In this utility model embodiment, the index finger portion 301 and the middle finger portion 303 are respectively placed on the user's index and middle fingers, both of which have an arc shape to fit the natural curvature of the fingers; during the chopping and cutting process, the pressing action of three fingers (thumb, index finger, and middle finger) combined with the force applied by the ring finger and little finger of the palm to grip the knife handle improves control precision and stability. Especially when handling harder ingredients, it can effectively prevent the kitchen knife from slipping or slipping out of the hand, ensuring safety while improving the chopping and cutting operation experience, enhancing grip comfort, and strengthening the force application effect.

[0035] Working principle: First, place the back groove 4 of the auxiliary tool onto the back of the knife near the handle of the kitchen knife. The back groove 4 fits tightly with the back of the kitchen knife, so that the tool is firmly fixed on the back of the kitchen knife. The front end 1 is close to the front side of the kitchen knife (the side closer to the food), and the right side of the rear end 3 is close to the rear side of the kitchen knife (the side away from the food), forming a complete wrapping structure. The user holds the auxiliary tool with his fingers, with his thumb on the thumb part 101 below the front end 1, and his index and middle fingers resting on the index finger part 301 and middle finger part 303 on the left side of the rear end 3, respectively. His fingers are close to the protruding part of the middle end 2, forming an overall force-bearing surface. The palm, ring finger, and little finger hold the knife handle. When performing operations such as cutting and chopping bones, the user applies downward pressure with their wrist, and the thumb presses against the front end 1 to form a downward fulcrum. The torque effect near the cutting point enhances the force application. The soft layer (silicone) on the outer surface of the middle end 2 effectively prevents slippage and improves grip stability. The finger groove design ensures that the fingers do not shift, improving control precision. Throughout the process, the auxiliary tool moves synchronously with the kitchen knife, without loosening or interfering with the operation of the blade. After completing the chopping or cutting operation, the auxiliary tool can be easily removed by simply pulling it upwards. The tool can be washed separately to maintain kitchen hygiene, and can be reinstalled for the next use.
