[0030] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0031] A knife sharpener is a tool used to sharpen and sharpen knives (such as blades, cutting tools, etc.) to restore their sharpness and cutting effect. Knife sharpeners are commonly used in home kitchens, industrial production and handicrafts to ensure that knives remain sharp and improve work efficiency and safety.

[0032] Traditional knife sharpeners may not have a precise guide system, and the resistance during sharpening is large, which makes it difficult for users to maintain a consistent angle when sharpening. This not only increases the difficulty of operation, but may also lead to unsatisfactory sharpening results.

[0033] Reference Figure 1-5 As shown, a knife sharpener with a rolling guide mechanism comprises:

[0034] A main body 1, with a grinding blade 2 disposed on the main body 1;

[0035] A guide mechanism is arranged on one side of the blade grinding 2, and the guide mechanism includes a roller 3 rotatably mounted above the main body 1;

[0036] The tool body 5 abuts against the outer side surface of the roller 3, and the tool edge 6 abuts against the sharpening blade 2, and the roller 3 rolls to assist the tool in sharpening.

[0037] By providing a rolling guide mechanism on the knife sharpener, the problems of the traditional knife sharpener lacking precise guidance and high grinding resistance are effectively solved. The knife sharpener includes a main body 1, on which a sharpening blade 2 is arranged, and a guide mechanism is arranged on one side of the sharpening blade 2. The guide mechanism includes a roller 3 rotatably mounted on the top of the main body 1. When the tool body abuts against the outer side of the roller 3 and the tool blade abuts against the sharpening blade 2, the rolling of the roller 3 assists the tool in sharpening. Among them, the roller 3 provides a stable guide, allowing the user to maintain a consistent sharpening angle, significantly reducing the grinding resistance, thereby improving the efficiency and effect of sharpening. In addition, the user operation is easier and the sharpening process is more precise, ensuring that the tool always maintains the best sharpness.

[0038] In order to facilitate grinding of both sides of the knife blade, two groups of guide mechanisms are provided.

[0039] The grinding blades 2 are provided in two groups, and a group of guide mechanisms is provided on one side of each group of the grinding blades 2.

[0040] This design provides two sets of guide mechanisms and two sets of sharpening blades 2 on the sharpener, so that both sides of the knife edge can be sharpened conveniently. Each set of sharpening blades 2 is provided with a set of guide mechanisms on one side, and the user can use the two sets of guide mechanisms and sharpening blades 2 to sharpen both sides of the knife when sharpening the knife. The benefits of this design include:

[0041] By arranging two sets of guide mechanisms and two sets of grinding blades 2 on the knife sharpener, both sides of the knife blade can be conveniently sharpened. A set of guide mechanisms is arranged on one side of each set of grinding blades 2. When sharpening the knife, the user can use the two sets of guide mechanisms and the grinding blades 2 to grind both sides of the knife blade respectively, ensuring that both sides of the knife blade can be evenly sharpened, thereby improving the overall sharpness and service life of the knife.

[0042] The user does not need to frequently adjust the tool position, but only needs to switch to another set of guide mechanisms and sharpening blade 2, which makes the operation more convenient and efficient. The two sets of guide mechanisms provide stable double-sided guides to ensure consistent sharpening angles and more accurate grinding. At the same time, the double-set design reduces the time required for sharpening and improves work efficiency, which is particularly suitable for environments that require frequent sharpening.

[0043] The diameter of the roller 3 facing the grinding blade 2 of the same group is gradually reduced, forming an inclined surface 31. The design of the inclined surface 31 allows the angle of the tool to be automatically adjusted through the inclined surface 31 of the roller 3 when the tool body abuts against the outer side of the roller 3 when the tool body is slid, so that the tool is more closely fitted to the grinding blade 2, thereby ensuring the grinding effect.

[0044] The inclined surface 31 can ensure that the tool edge always maintains an optimal contact angle with the grinding blade 2, thereby improving the grinding accuracy and the sharpness of the blade.

[0045] The inclined surface 31 of the roller 3 can automatically adapt to cutters of different thicknesses and shapes, reducing the frequency and difficulty of the user adjusting the position of the cutter.

[0046] At the same time, the gradual diameter design of the roller 3 can guide the tool more smoothly, reduce the resistance during the grinding process, and make the sharpening process easier. By ensuring the optimal contact angle between the tool edge and the sharpening blade 2, unnecessary wear is reduced, thereby extending the service life of the sharpening blade 2. The user can more easily maintain the correct angle of the tool during operation, without the need for frequent adjustments, and sharpening is faster and more convenient.

[0047] The angle of the inclined surface 31 is 30-60°. In this embodiment, the angle of the inclined surface 31 is preferably 45°.

[0048] The surfaces of the roller 3 near both ends are embedded with anti-skid rings 32. The anti-skid rings 32 are made of rubber material.

[0049] Since the rubber material has a high friction coefficient, the provision of the anti-slip ring 32 can effectively increase the friction between the tool and the roller 3, prevent the tool from sliding during the grinding process, and ensure grinding stability. The rubber material is relatively soft, which can reduce the wear of the tool when it is in direct contact with the roller 3 to a certain extent, and extend the service life of the tool.

[0050] In addition, the rubber anti-slip ring 32 can play a certain role in shock absorption, reducing the vibration generated during the grinding process, making the grinding operation more stable and improving the grinding quality.

[0051] The anti-slip ring 32 can prevent the knife from accidentally slipping off, improving the safety of the knife sharpening operation, especially when rotating at high speed or moving quickly, ensuring safer and more reliable operation. The rubber anti-slip ring 32 can adapt to knives of different types and materials, enhancing the application range of the knife sharpener and making the device more versatile. The rubber material has good wear resistance and elasticity, and the anti-slip ring 32 is not easy to wear, which increases the overall durability and service life of the knife sharpener.

[0052] In order to achieve a more stable installation state of the roller 3, the main body 1 includes a support seat 11, a groove 111 is provided above the support seat 11, and both sides of the groove 111 protrude upward to form a support portion 112. A shaft rod 33 is extended outwardly on both sides of the roller 3. The roller 3 is inserted into the groove 111, and the shaft rod 33 is rotatably inserted on the support portion 112.

[0053] The main body 1 further comprises an upper cover 12 sleeved on the support seat 11, a first through slot 121 is arranged on the upper cover 12 corresponding to the position of the roller 3, and a part of the upper part of the roller 3 passes through the first through slot 121;

[0054] A second through slot 122 is provided above the upper cover 12 at a position corresponding to the grinding blade 2 , and a portion of the upper portion of the grinding blade 2 passes through the second through slot 122 .

[0055] A plurality of positioning rods are arranged below the upper cover 12 , and positioning holes are arranged above the support seat 11 corresponding to the positions of the positioning rods. The upper cover 12 is buckled and fixed on the support seat 11 by inserting the positioning rods into the positioning holes.

[0056] The support seat 11 serves as a basic component, and the support seat 11 provides stable support for the entire device. The sink 111 is located above the support seat 11, and is used to accommodate the roller 3. The support parts 112 protruding upward on both sides are used to install the shaft rod 33. The shaft rod 33 extending outward on both sides of the roller 3 is inserted into the support part 112, and the roller 3 itself is embedded in the sink 111. The upper cover 12 is sleeved on the support seat 11, and cooperates with the roller 3 and the grinding blade 2 through the first through groove 121 and the second through groove 122 respectively. Positioning rod and positioning hole: The positioning rod under the upper cover 12 corresponds to the positioning hole above the support seat 11. After the roller 3 and the grinding blade 2 are installed, the upper cover 12 can be fixed on the support seat 11 by inserting the positioning rod into the positioning hole, and at the same time, a certain constraint is exerted on the roller 3 and the grinding blade 2.

[0057] Through the design of the sink 111 and the support portion 112, the roller 3 is stably installed, which reduces shaking during operation and improves safety.

[0058] The design of the upper cover 12 makes it easy to disassemble and install the roller 3 and the grinding blade 2, and is convenient for maintenance and replacement.

[0059] In addition, the first through slot 121 and the second through slot 122 ensure the accurate position of the roller 3 and the grinding blade 2 during operation, thereby improving the grinding accuracy. Through the cooperation of the positioning rod and the positioning hole, the upper cover 12 can be firmly fixed on the support seat 11, making the entire device compact and space-saving. The bottom of the positioning rod can also be reinforced by bolts.

[0060] The length of the first through slot 121 is smaller than that of the roller 3. The exposed portion of the roller in the upper cover 12 is reduced, thereby increasing the stability of the roller 3 and preventing the roller 3 from affecting the grinding effect due to excessive shaking during use.

[0061] The top of the grinding blade 2 is higher than the upper surface of the upper cover 12. The top of the grinding blade 2 is higher than the upper surface of the upper cover 12, which ensures that the exposed part of the blade is sufficient when in use, and can be ground more effectively, improving the grinding efficiency and effect. At the same time, the space above the upper cover 12 is utilized, making the structure of the entire device more compact, without adding additional space.

[0062] The side of the grinding blade 2 is tilted inwards from the middle to form a tilted portion 21. The tilted portion 21 passes through the second through slot 122. The top surface of the grinding blade 2 is higher than the upper surface of the upper cover 12. The blade can fit the cutting edge of the tool better during the grinding process, improving the grinding accuracy and uniformity. The design of the tilted portion 21 enables the grinding blade 2 to contact the tool at a more appropriate angle, thereby optimizing the grinding angle, reducing the resistance during grinding, and extending the service life of the tool and the grinding blade 2.

[0063] The first through slot 121 and the second through slot 122 allow the upper cover 12 to maintain position constraints on the roller 3 and the grinding blade 2 after installation, so that the roller 3 and the grinding blade 2 are stable and not easy to fall off during the grinding process, thereby improving safety in use.
