Description

Scissors with precise cutting and anti-splitting blade structure

This invention is a pair of scissors with a precise cutting and anti-splitting blade structure. Specifically, the blade has specially ground bevels and cut surfaces on the front and outer sides of the blade, which form a thinner and more pointed tip. This prevents materials (such as paper) from splitting during cutting, thereby improving cutting accuracy and smoothness, while also enhancing aesthetics.

In daily life, scissors are a basic tool widely used in various cutting operations, including cutting materials such as paper, cloth, and plastic packaging. Their structure typically consists of two staggered blades, which are driven by the user to slide against each other to complete the cutting. Due to their ease of operation and good maneuverability, scissors are widely used in various occasions such as offices, homes, craft production, and industrial processing, becoming one of the indispensable basic cutting tools.

However, conventional scissors, as shown in FIG. 1 , typically have blades 10 of a certain thickness, particularly at the distal end of the blade. Due to structural, cost, and processing requirements, the blades 10 are typically uniformly thick throughout, resulting in a thicker tip at the distal end and a blunted design. Consequently, when cutting, the thickness of the distal end of the scissors often compresses the material being cut at the distal end due to the thickness of the blades 10. This can easily cause the paper to become split, uneven, or misaligned, thereby affecting the overall quality and aesthetics of the cut paper.

Furthermore, existing scissor tips struggle to achieve a clean, sharp cut when cutting small or precision-critical materials. Uneven force or interference from the blade thickness often causes the cutting line to shift or the material to deform, resulting in wrinkles or tears. These issues are particularly pronounced in delicate crafts, document processing, or decorative applications, reducing user efficiency and limiting the scissors' practicality and applicability for high-precision cutting applications.

In view of this, the creator of this invention has specifically researched and improved the blade, shearing and anti-splitting structural configuration, hoping to improve the above problems with a better creation. After a long period of research and development and continuous testing, this creation came into being.

Therefore, this invention is to solve the above-mentioned problem. In order to achieve the above purpose, we, the creators, provide a pair of scissors with precise cutting and anti-splitting blade structure, which includes: two blades, which are arranged in correspondence with each other, each blade having a blade body portion, and a cutting edge formed on one side, and a blade back formed on the other side; the blade body portion is thinned and ground at its front end and tilted to form a bevel, and the blade back portion is also provided with a pointed grinding design at its front end, which is tilted toward the cutting edge, and the bevel and the cut surface correspond to the formation of a pointed tip at the front end of the blade body portion.

According to the above-mentioned scissors with precise cutting and anti-splitting blade structure, the blade portion is slightly inclined, and the slope of the inclined surface is greater than the slope of the blade portion.

According to the above-mentioned scissors with precise cutting and anti-splitting blade structure, the tip is arranged in a slightly triangular shape at the inclined surface.

According to the above-mentioned scissors with precise cutting and anti-splitting blade structure, the cutting surface is slightly straight or arc-shaped and inclined.

According to the above-mentioned scissors with precise cutting and anti-splitting blade structure, the blade body is further provided with a large cutting surface at one end opposite to the blade back, and the blade is provided at the side of the large cutting surface, and the large cutting surface forms the tip at the front end.

According to the above-mentioned scissors with precise cutting and anti-splitting blade structure, the blades are arranged in a staggered manner corresponding to each other.

According to the above-mentioned scissors with precise cutting and anti-splitting blade structure, the colors of the bevel and the cutting surface are the same as or different from the color of the blade body.

Based on the above description and settings, it is clear that this creation has the following advantages and functions, which are described in detail below:

1. This invention incorporates a bevel and a cut surface at the front end of the blade to create a pointed tip. This creates a thin, pointed end. This improves the poor cutting performance of traditional scissors due to the thicker tip. This allows the invention to contact the material being cut with a smaller contact area during the cutting process, thereby reducing the degree of compression on the material (such as paper). This effectively avoids defects such as splitting, unevenness, or misalignment when cutting thin materials such as paper or cardboard. This improves cutting accuracy and ensures a smooth and consistent cut line, resulting in a cleaner and more delicate overall cutting effect. It also facilitates more flexible and precise control when cutting small, complex, or curved materials, meeting the demand for high-quality cutting operations.

2. By incorporating bevels and facets on the front of the blade, this design not only improves the end-of-cutting performance of traditional scissors, but also exhibits greater refinement and a cleaner visual effect in appearance, thereby enhancing the overall aesthetics and market appeal of the product.

This invention is a pair of scissors with a blade structure that enables precise cutting and prevents splitting. Its implementation methods, features, and effectiveness are detailed below with several preferred feasible embodiments and accompanying diagrams, so that you can gain a deeper understanding and endorse this invention.

First, please refer to Figures 2 to 5. This invention is a pair of scissors with a precise cutting and anti-splitting blade structure, which includes:

The two blades 1 are arranged in a mutually corresponding manner. As can be seen, the blades 1 are arranged in a staggered manner. A handle is provided at the rear end of each blade 1, so that the user can apply force to the blades 1 through the handle to drive the blades 1 to slide toward each other to achieve the shearing function. Each blade 1 has a blade body 11, and a cutting edge 12 is formed on one side and a blade back 13 is formed on the other side. As can be seen, the cutting edge 12 can be a sharp blade portion, so that as mentioned above, the cutting edge 12 can be brought into contact with each other to achieve shearing.

The blade portion 11 is thinned and ground at its front end to form a bevel 111, as shown in Figures 3 to 5, and the blade back 13 is also provided with a cutting surface 14 with a pointed grinding design at its front end corresponding to the blade 12, and the bevel 111 and the cutting surface 14 are corresponding to the tip 15 with the end face thinned and the side pointed at the front end of the blade portion 11. This allows the tip 15 to have a relatively thin structure, giving the front end of the blade 1 a narrow and sharp contact shape; and through the provision of the cutting surface 14, the tip 15 can be slightly triangular at the inclined surface 111, giving it thin and sharp characteristics. The cutting surface 14 can be slightly inclined in a straight line or in an arc shape according to processing or usage requirements. However, this is only an example and is not intended to be limiting.

Thus, the tip 15 structure formed by the bevel 111 and the cutting surface 14 of this invention makes its end thickness significantly smaller than that of conventional scissors. Therefore, the range of material pressure during the cutting process can be effectively reduced, avoiding undesirable phenomena such as paper splitting, warping, and misalignment. This can improve the accuracy of cutting and ensure the smoothness and consistency of the cutting line, making the overall cutting effect more neat and delicate. The cutting area is as precise as that of a cutting tool (such as a utility knife). It also helps to achieve more flexible and precise control when cutting small, complex or curved materials, so as to meet the demand for high-quality cutting operations.

Furthermore, the structural configuration of the tip 15 creates a sharp visual effect at the front end of the invention, making the tip 15 highly recognizable and aesthetically pleasing. Furthermore, by having the colors of the bevel 111 and the cut surface 14 be the same or different from the color of the blade 11, the color difference helps the user determine the cutting position during operation, thereby enhancing the overall aesthetics of the design.

Continuing with the configuration of the blade portion 11, in one embodiment, the blade portion 11 can be slightly tilted to accommodate precise processing and shearing. In this case, the slope of the inclined surface 111 is greater than the slope of the blade portion 11, so that the tip 15 can have a thinner structure, thereby achieving the aforementioned shearing accuracy and the effect of preventing splitting.

As for the formation of the blade body 11 and the blade edge 12, in one embodiment, the blade body 11 is further provided with a large cutting surface 16 at one end relative to the blade back 13, and the blade edge 12 is provided at the side of the large cutting surface 16, and the large cutting surface 16 forms the tip 15 at the front end. This arrangement can facilitate the processing of the blade 12 and can also help guide the material into the shearing area, thereby improving the shearing stability and linear accuracy.

In summary, the technical means disclosed in this invention are not only unprecedented but also truly achieve the intended purpose and efficacy. Therefore, they are both novel and progressive, and are truly considered novel under the Patent Law. In terms of their overall structure, they meet the statutory requirements of the Patent Law. Therefore, a new patent application is filed in accordance with the law.

However, the above description is merely a preferred embodiment of this invention and should not be used to limit the scope of implementation of this invention. In other words, all equivalent changes and modifications made within the scope of the patent application and the content of the specification of this invention should still fall within the scope of coverage of this invention's patent.
