Description

Technical Field

[0001] The present application relates to the technical field of cutting tools, and in particular to a cutting tool. Background Art

[0002] The knives used in daily life are mainly used for cutting various types of food, such as fruits, bread, meat, etc.; due to the different types of food being cut, the blade thickness and blade inclination angle of the cutting knives used also need to be selected and set differently. If a knife with a small blade inclination angle is used to cut food, it is easy to cause the cutting knife to chip or break, resulting in damage to the knife.

[0003] Based on the above situation, homes often need to be equipped with multiple knives to cope with cutting different types of food. However, when actually choosing, novice users often find it difficult to intuitively judge what type of knife is needed to cut the corresponding food, and knives are still damaged. Therefore, there is still room for improvement in the cutting knives on the market. Utility Model Content

[0004] Based on this, the present application provides a cutting knife that can be used for cutting different types of food, and at the same time has good structural strength and can reduce the risk of chipping or breaking.

[0005] The present application provides a cutting tool that adopts the following technical solution:

[0006] A cutting tool comprises a handle and a blade head fixed to the handle, wherein the two side edges of the blade head in the width direction are respectively arranged as a first cutting edge outer edge and a second cutting edge outer edge; a reinforcing ridge is respectively provided on the front and back sides of the blade head, and the distance from the reinforcing ridge to the first cutting edge outer edge is greater than the distance from the reinforcing ridge to the second cutting edge outer edge.

[0007] By adopting the above technical solution, the cross-sectional area of the blade can be increased by providing a reinforcing ridge, thereby increasing the impact resistance of the blade when cutting meat, reducing the possibility of chipping of the blade edge or breaking of the entire blade, and providing the blade with good structural strength. Furthermore, by making the distance from the reinforcing ridge to the first cutting edge greater than the distance from the reinforcing ridge to the second cutting edge, the blade inclination angle of the region between the first cutting edge and the reinforcing ridge is smaller than the blade inclination angle of the region between the second cutting edge and the reinforcing ridge. As a result, the impact resistance of the region between the first cutting edge and the reinforcing ridge is relatively low, making it suitable for cutting softer foods, while the impact resistance of the region between the second cutting edge and the reinforcing ridge is relatively high, making it suitable for cutting harder foods. Novice users can quickly and easily determine the blade edge to use by judging the distance from the cutting edge to the reinforcing ridge. The knife is easy to use and can be applied to cutting different types of food.

[0008] Optionally, a plurality of arc cuts are provided in the middle section of the outer edge of the first cutting edge.

[0009] By adopting the above-mentioned technical solution, when the outer edge of the first cutting edge of the cutting tool is used to cut soft food, the setting of the arc incision can reduce the resistance encountered by the cutter head; moreover, when the cutting tool is used to cut fruit peels, the setting of the arc incision can effectively control the flow direction of the chips and reduce the occurrence of chips splashing or sticking to the blade.

[0010] Optionally, the side edge of the reinforcing ridge away from the cutter head has a smooth rounded transition and is provided with a sandblasted surface.

[0011] By adopting the above technical solution, when the user uses the cutting tool to cut fruit, the user's fingers can rest against the sandblasted surface of the reinforced edge. The setting of the sandblasted surface can increase the friction between the hand and the reinforced edge, thereby improving the convenience and flexibility of the user when cutting.

[0012] Optionally, the surface of the cutter head is provided with an aluminum oxide coating.

[0013] By adopting the above technical solution, the provision of the aluminum oxide coating can improve the hardness and wear resistance of the cutter head surface, thereby helping to maintain a good service life of the tool.

[0014] Optionally, the knife handle has multiple outer edges, and the surface of each outer edge is provided with friction lines.

[0015] By adopting the above technical solution, the arrangement of the outer edge surface and the friction pattern can improve the convenience for the user to hold the knife handle, thereby making it convenient to use the cutting knife to cut food.

[0016] Optionally, the cutting tool also includes a safety sheath for covering the blade head, the safety sheath includes two plastic half-sheaths, one side edges of the two plastic half-sheaths are hinged to each other, and the other side edges are detachably connected by a buckle structure; a receiving groove is provided on the side of the plastic half-sheath, and when the two plastic half-sheaths are pressed against each other and remain fixed, the two receiving grooves together form a first receiving cavity for receiving the blade head.

[0017] By adopting the above technical solution, when the cutting tool is used, the cutting head of the cutting tool is matched into the receiving groove of the plastic half-sleeve, and then the other plastic half-sleeve is rotated to cover the cutting head. The two plastic half-sleeves are connected to each other using the snap-fit structure. The two plastic half-sleeves can protect the cutting head, making it convenient for the user to store and carry the cutting tool.

[0018] Optionally, the buckling structure includes a buckling seat and a buckling groove that is buckled and adapted to the buckling seat, and the buckling seat and the buckling groove are respectively correspondingly arranged on the two plastic half-shells.

[0019] By adopting the above technical solution, the two plastic half-shells can be easily connected and disassembled through the snap-fit cooperation between the snap-fit seat and the snap-fit groove, thereby facilitating the storage and use of the cutting tool.

[0020] Optionally, an outer edge portion is integrally formed on the outer edge of the handle close to the blade head, and a placement groove is provided on the side of the plastic half-sleeve. When the two plastic half-sleeves are pressed against each other and remain fixed, the two placement grooves jointly form a second accommodating cavity for accommodating the outer edge portion.

[0021] By adopting the above technical solution, when storing the cutting tool, the cutting tool head is matched into the receiving groove of the plastic half-sheath, and the outer edge of the handle is matched into the placement groove of the plastic half-sheath; when the two plastic half-sheaths are connected to each other, the safety sheath protects the cutting tool head and also wraps the outer edge, thereby reducing the possibility of the safety sheath moving outward and detaching from the cutting tool head during the carrying process of the cutting tool, and ensuring that the safety sheath provides good protection for the cutting tool head.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The reinforcement ribs can increase the cross-sectional area of the cutter head, thereby increasing the impact resistance of the cutter head when cutting meat, reducing the possibility of chipping of the cutter head edge or breaking of the cutter head, and giving the cutter head good structural strength;

[0024] 2. By making the distance from the reinforcing edge to the outer edge of the first cutting edge greater than the distance from the reinforcing edge to the outer edge of the second cutting edge, novice users can quickly and easily determine the cutting edge to use by judging the distance from the outer edge of the cutting edge to the reinforcing edge. This makes the knife easy to use and suitable for cutting different types of food.

[0025] 3. By setting two plastic half-shells to form a safety sheath, after the tool is placed in the receiving slot, the two plastic half-shells are connected to each other using a buckle structure. The two plastic half-shells can protect the tool head, making it easy for users to store and carry the cutting tool. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following is combined with Figure 1-4 This application is described in further detail.

[0032] Example 1:

[0033] The embodiment of the present application discloses a cutting tool.

[0034] Reference Figure 1 A cutting tool includes a handle 1 and a blade head 2. The handle 1 has an outer edge 12 integrally formed thereon, and the blade head 2 is fixed to the side of the handle 1 provided with the outer edge 12. In this embodiment, the handle 1 has a prismatic cross-section, with four external facets, and chamfered transitions between adjacent external facets. Furthermore, each external facet is provided with friction grooves 11. The friction grooves 11 increase the friction resistance between the user's hand and the handle 1, making it easier for the user to grip the handle 1.

[0035] Also refer to Figure 2 In this embodiment, the surface of the cutter head 2 is spray-coated with an aluminum oxide coating 25 to increase the hardness and wear resistance of the cutter head 2, thereby maintaining a long tool life. A first cutting edge 21 and a second cutting edge 22 are provided on both sides of the cutter head 2 in the width direction. Furthermore, a reinforcing ridge 23 is provided on both the front and back surfaces of the cutter head 2. Beveled transitions form between the reinforcing ridge 23 and the first cutting edge 21, and between the reinforcing ridge 23 and the second cutting edge 22, resulting in a diamond-shaped cross-section of the cutter head 2. The reinforcing ridge 23 is provided to enhance the structural strength of the cutter head 2.

[0036] Moreover, the distance between the reinforcing edge 23 and the first cutting edge outer edge 21 is greater than the distance between the reinforcing edge 23 and the second cutting edge outer edge 22, so that the blade inclination angle of the area between the first cutting edge outer edge 21 and the reinforcing edge 23 is smaller than the blade inclination angle of the area between the second cutting edge outer edge 22 and the reinforcing edge 23; based on this, the impact resistance of the area between the first cutting edge outer edge 21 and the reinforcing edge 23 is relatively small, and can be used for cutting softer food, while the impact resistance of the area between the second cutting edge outer edge 22 and the reinforcing edge 23 is relatively large, and can be used for cutting harder food.

[0037] In addition, back to Figure 1The outer edge 21 of the first cutting edge is provided with a plurality of arcuate notches 24. In this embodiment, there are three arcuate notches 24, all located in the middle section of the outer edge 21 of the first cutting edge, with intervals between adjacent arcuate notches 24. The provision of the arcuate notches 24 effectively controls the flow of chips when cutting the peel, reducing the occurrence of chips splashing or sticking to the blade. The side edge of the reinforcing edge 23 away from the blade head 2 has a smooth rounded transition and is sandblasted to form a sandblasted surface 231. The provision of the sandblasted surface 231 increases the friction between the hand and the reinforcing edge 23, improving the convenience and flexibility of the user when cutting.

[0038] Example 2:

[0039] The embodiment of the present application discloses a cutting tool.

[0040] Reference Figure 3 The embodiment of the present application discloses a cutting tool, and the remaining components are the same as those in Example 1, and are not described one by one here; the difference from Example 1 is that the cutting tool in this embodiment also includes a safety sheath 3, and the safety sheath 3 includes two plastic half-sheaths 31, and one side edge of the two plastic half-sheaths 31 is hinged to each other, while the other side edges of the two plastic half-sheaths 31 are detachably connected by a buckle structure 32.

[0041] Specific reference Figure 4 The side edge of the plastic half-sleeve 31 is provided with an integrally molded molding base 313, and the buckling structure 32 includes a buckling seat 321 and a buckling groove 322. The buckling seat 321 is arranged on the molding base 313 of one of the plastic half-sleeves 31, and the buckling groove 322 is opened on the molding base 313 of the other plastic half-sleeve 31; when the two plastic half-sleeves 31 rotate toward each other to a state of mutual abutment, the buckling seat 321 can be deformed and clamped in the buckling groove 322 to achieve detachable fixation of the two plastic half-sleeves 31.

[0042] Back to Figure 3 Each side of the plastic half-sheath 31 is provided with a receiving groove 33 and a placement groove 34, and the receiving groove 33 and the placement groove 34 are partially connected; when the two plastic half-sheaths 31 are pressed against each other and remain fixed, the two receiving grooves 33 can jointly form a first receiving cavity for receiving the cutter head 2, so as to wrap and protect the cutter head 2, making it convenient for the user to store and carry the cutting tool; the two placement grooves 34 can jointly form a second receiving cavity for receiving the outer edge portion 12, thereby wrapping the outer edge portion 12, which can reduce the possibility of the safety cover 3 moving outward and detaching from the cutter head 2 during the carrying of the cutting tool, thereby ensuring that the safety cover 3 provides good protection for the cutter head 2.

[0043] The above are preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
