Description

Technical Field

[0001] The invention belongs to the technical field of blades, and in particular relates to a cicada-shaped cutting tool. Background Art

[0002] Traditional blades are roughly divided into flat blades, outwardly protruding arc blades and serrated blades.

[0003] When a traditional straight blade is at the position where cutting is required, all blades contact the surface of the object to be cut at the same time. Therefore, in order to maintain sufficient cutting pressure, the required cutting force is the largest.

[0004] When the blade of a traditional curved scimitar is at the position where cutting is required, although only part of the blade contacts the surface of the object being cut, since each small section thereof is relatively straight, the fibers of the object being cut cannot be smoothly cut, and a large cutting force is required.

[0005] When a traditional serrated blade is at a position where cutting is required, the tips of all the teeth will contact the object at the same time. The contact area is too small at the beginning, and too large at the later stage. During the cutting process, it is necessary to have a larger peak cutting force while ensuring the cutting pressure.

[0006] Insects in nature have evolved many special structures beyond current human cognition through hundreds of millions of years of evolution. For example, the ovipositor of female cicadas has evolved a unique structure in order to insert it into the wood of tree branches to lay eggs safely.

[0007] In the case of female cicadas with wavy edges on the outer side of the cone or needle-shaped front end of the ovipositor, this is usually to help the female cicada pierce the protective layer and tissue of the plant more easily. This wavy edge design has the following functions and explanations:

[0008] Weakening plant tissue: The wavy blades can provide additional cutting and penetration power, allowing female cicadas to more easily weaken the outer layer of the plant. Plants often have tough protective layers, such as bark, and the wavy blades can help female cicadas overcome this resistance. Increased stability: The shape of the wavy blades can increase the stability of the ovipositor during the piercing process. This helps ensure that the ovipositor is not easily deviated when entering the plant tissue, and maintains a consistent depth and direction during the establishment of the egg-laying channel. Reduced damage: The wavy blade design can reduce tearing and damage to plant tissue, thereby reducing plant damage to oviposition. This helps ensure that the plant can still continue to grow and survive for a period of time. Improved efficiency: The wavy blades can increase the efficiency of the ovipositor, making it easier to penetrate plant tissue so that female cicadas can establish the egg-laying channel and deposit eggs faster. In summary, the wavy blades are an important adaptive feature of the female cicada's ovipositor, which helps them successfully place their eggs safely inside the plant.

[0009] Therefore, there is a need for a cicada-shaped cutter that can utilize the ovipositor of a female cicada to save effort and power better. Summary of the invention

[0034] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the present invention will be briefly introduced below in combination with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structure of the drawings is only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0035] Embodiment 1:

[0036] like Figures 1 to 5 As shown, this embodiment provides a cicada-shaped tool, including

[0037] A tool handle, which is fixed to the frame;

[0038] A blade, one end of which is fixed to the handle, and the blade is a flat, pointed structure;

[0039] The blade includes a plurality of blade teeth arranged on the side of the blade body, and the combined structure of the blade and the blade body is shaped like the ovipositor of a cicada; the tooth tips of the blade teeth at the front end of the blade body are inclined forward, and the tooth tips of the blade teeth at the rear end of the blade body are inclined backward; and the tooth tip height of the blade teeth in the middle of the side of the blade body is higher than the tooth tip height at the front and rear ends of the blade body.

[0040] Embodiment 2:

[0041] like Figure 1 As shown, this embodiment provides a cicada-shaped tool, including:

[0042] A knife handle 100, which is fixed to the frame;

[0043] A blade body 200, one end of which is fixed to the handle 100, and the blade body 200 is an isosceles triangle;

[0044] The blade 300 includes a plurality of teeth disposed at the side of the blade body. The number of teeth can be determined as needed. When the number of teeth is nine, it includes a first tooth 301, a second tooth 302, a third tooth 303, a fourth tooth 304, a fifth tooth 305, a sixth tooth 306, a seventh tooth 307, an eighth tooth 308 and a ninth tooth 309; the first tooth 301, the second tooth 302, the third tooth 303, the fourth tooth 304, the fifth tooth 305, the sixth tooth 306, the seventh tooth 307, the eighth tooth 308 and the ninth tooth 309. The teeth 309 are fixed along the side edge of the blade 200 in sequence from the other end of the blade body 200 to one end of the blade body 200; the first tooth 301, the second tooth 302, the third tooth 303, the fourth tooth 304, the fifth tooth 305, the sixth tooth 306, the seventh tooth 307, the eighth tooth 308 and the ninth tooth 309 are all arcuate; the tooth tips of the first tooth, the second tooth, the third tooth and the fourth tooth are inclined forward; the tooth tips of the seventh tooth, the eighth tooth and the ninth tooth are inclined backward; the tooth tip height of the teeth in the middle of the side of the blade body is higher than the tooth tip height at the front and rear ends of the blade body.

[0045] The present invention uses the above-mentioned arcuate blade 300 to replace the straight blade formed on the outer edge of the ordinary blade body 200, and can make the blade 300 more labor-saving to cut the required position through the angle of bionics. Figure 3 The plowshare and Figure 1 , 2 The blade of the food processor and the blade of the food processor (not shown) can use the cicada-shaped cutter of the present invention to reduce cutting resistance and improve cutting efficiency. The shape of the blade 300 can be used in agriculture and home use. The present invention uses the unique structure of the cicada to reduce the resistance of the blade.

[0046] like Figure 3 As shown, the blade shape of the plowshare has one side that is a straight surface, which is adapted to the straight blade 300, and the side surface that is a concave arc surface, which is adapted to the concave curved blade 300.

[0047] Among them, not shown in the figure, the blade of the food processor is also an arc-shaped blade protruding outward, which can be adapted to the curved blade 300 protruding outward.

[0048] Specifically, when the traditional straight blades are at the position where cutting is required, all the blades contact the surface of the object to be cut at the same time. Therefore, in order to maintain sufficient cutting pressure, the required cutting force is the largest.

[0049] When the blade of a traditional curved scimitar is at the position where cutting is required, although only part of the blade contacts the surface of the object being cut, since each small section thereof is relatively straight, the fibers of the object being cut cannot be smoothly cut, and a large cutting force is required.

[0050] When a traditional serrated blade is at a position where cutting is required, the tips of all the teeth will contact the object at the same time. The contact area is too small at the beginning, and too large at the later stage. During the cutting process, it is necessary to have a larger peak cutting force while ensuring the cutting pressure.

[0051] The present invention adopts the arcuate sawtooth blade 300 to cut the surface of an object, which can not only reduce the cutting force but also reduce the peak value of the cutting force, thereby cutting the surface more smoothly.

[0052] The present invention draws on the principle that the ovipositor of the female cicada can be inserted into a place where eggs can be placed with the most effort through the above-mentioned structure, and is configured with a special shape of the blade 300 of the above-mentioned knife.

[0053] The frame may be a user's hand, an output shaft of a motor, or a mechanical arm.

[0054] Among them, see Figure 1 , 2 The angle between the two sides of the other end of the blade body 200 is 28°, and the two groups of blade edges 300 are symmetrically fixed on the outer edges of the two sides of the blade body 200.

[0055] The present invention has a blade tip angle of 28°, so that when the entire blade body is inserted into an object to be inserted, it can achieve maximum labor saving and maximum efficiency in inserting the object to be inserted. The present invention can achieve better insertion of the object to be inserted through the two sets of blades 300.

[0056] Among them, see Figure 1 , 2 The ratio of the arc radii of the first tooth 301, the second tooth 302, the third tooth 303, the fourth tooth 304, the fifth tooth 305, the sixth tooth 306, the seventh tooth 307, the eighth tooth 308 and the ninth tooth 309 is 2.44:3.51:4.1:5.6:6.53:7.44:8.99:11.92:11.84.

[0057] The present invention can configure different radii based on different lengths through the above-mentioned different radii, so that the radius in the middle is larger, and the central angle gradually becomes smaller at a position close to one end of the blade body 200, so that the blade body 200 can reduce the resistance as much as possible after the blade body 200 is inserted into the required insertion position from the tip of the other end, and reduce the cutting force and peak force, saving effort and power.

[0058] See also Figure 1 , 2The center angle of the arc of the first tooth 301 is 131°; the center angle of the arc of the second tooth 302 is 100°; the center angle of the arc of the third tooth 303 is 118°; the center angle of the arc of the fourth tooth 304 is 115°; the center angle of the arc of the fifth tooth 305 is 119°; the center angle of the arc of the sixth tooth 306 is 146°; the center angle of the arc of the seventh tooth 307 is 141°; the center angle of the arc of the eighth tooth 308 is 136°; the center angle of the arc of the ninth tooth 309 is 108°.

[0059] The present invention can configure different central angles based on different lengths through the above-mentioned different central angles, so that the central angle in the middle is larger, and the central angle gradually becomes smaller at the position close to one end of the blade body 200, so that the blade body 200 can reduce the resistance as much as possible after the blade body 200 is inserted into the required insertion position from the tip of the other end, and reduce the cutting force and peak force, saving effort and power.

[0060] Among them, see Figure 1 , 2 The outer edges of the first tooth 301, the second tooth 302, the third tooth 303, and the fourth tooth 304 are provided with a first groove 400 which is inclined from the other side of the blade body 200 to one side of the blade body 200 and from the center line away from the blade body 200 to the center line close to the blade body 200.

[0061] The present invention makes the outer contour of the first four teeth more streamlined than the bow shape. On the one hand, it can prevent the first four teeth with smaller bow size from being subjected to excessive resistance and causing damage or connection failure. On the other hand, it reduces the resistance of the first four teeth to completely penetrate the object to be inserted, thereby achieving further labor and work saving.

[0062] Among them, see Figure 1 , 2 The first blade tooth 301 , the second blade tooth 302 , the third blade tooth 303 , and the fourth blade tooth 304 are all provided with fillets between their corresponding first blade grooves 400 .

[0063] The rounded corners provided in the present invention facilitate reducing the resistance of inserting the blade body 200 and saving effort and power as much as possible.

[0064] Among them, see Figure 1 , 2 The width of the knife handle 100 gradually decreases from being close to the knife body 200 to being far away from the knife body 200.

[0065] The present invention can further reduce the resistance of inserting the blade 200 through the knife handle 100 of the above structure.

[0066] Among them, see Figure 1 , 2 A set of blades 300 are fixed on one side of the blade body 200 .

[0067] In addition, the cicada-shaped tool in this scheme can also be applied to cross stirring blades, such as Figure 4 As shown, the blade is triangular in shape, or when applied to a curved mixing blade, the blade is crescent-shaped, such as Figure 5 shown. Figure 4 and Figure 5 The teeth of the cicada-shaped knives are all inclined toward the tip of the blade.

[0068] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
