Description

Technical Field

[0001] This utility model relates to the field of scissors technology, specifically to a novel pair of scissors that is ingeniously designed, highly efficient, and safe to use. Background Technology

[0002] Scissors, as a common double-edged tool, are widely used in daily life. When ordinary scissors are opened to cut, the point where the two blades intersect is in front, and the blade portion behind the intersection point is not effectively utilized.

[0003] In existing technologies, there are generally two ways to increase the effective cutting length of the scissors blade: one is to lengthen the scissor head, and the other is to increase the angle at which the two blades open. However, both of these methods have significant drawbacks: lengthening the blade head will increase the overall size of the scissors, thus reducing operational flexibility; increasing the angle at which the blades open makes it easier to touch other objects during use, and may even pose a safety risk of cutting fingers, resulting in a significant decrease in operational convenience. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention significantly increases the effective cutting length of the blade, providing a novel type of scissors with a sophisticated and reasonable structure that makes cutting more efficient and labor-saving.

[0005] To solve the above-mentioned technical problems, this utility model adopts the following technical solution, comprising: a blade head, a blade body, a handle, a shank, and rivets; the blade bodies are intersecting and fixedly connected by rivets, the front end of the blade body is the blade head, and the rear end is the handle, with one end of the handle embedded in the shank. The blade head is provided with a cutting edge. Its characteristic is that the blade head narrows from the connection point between the cutting edge and the blade body towards the central axis of the blade body, that is, it narrows from one side of the cutting edge towards the central axis of the blade body, and the narrowing method includes linear narrowing and arc narrowing. Specifically as follows:

[0006] Option 1: The width of the blade head is narrowed synchronously, and the width of the two blade heads is the same after narrowing. The range of the narrowing width value b at the root of the blade head is 1 / 8 to less than 1 / 2 of the width value at the front end of the blade body, that is, 1 / 8 ≤ b < 1 / 2;

[0007] Option 2: The width of the blade head is narrowed synchronously, with the narrowing width value at the root of one blade head being greater than that at the root of the other blade head, and the sum of the narrowing width values ​​on both sides being less than the width value at the front end of the blade body;

[0008] Option 3: The blade head is narrowed on only one side. The narrowed width value e at the root of the blade head on the narrowed side is 1 / 3 to 2 / 3 of the width at the front end of the blade body, that is, 1 / 3 ≤ e ≤ 2 / 3. The width at the root of the blade head on the other side is the same as the width at the front end of the blade body.

[0009] Of the three methods described above, when linear narrowing is used, the blade narrows uniformly and the blade is straight, which is beneficial for continuity and stability during cutting. Regardless of the blade opening angle, the effective cutting length of the blade increases, greatly improving the cutting efficiency of the scissors. When arc narrowing is used, the blade gradually narrows from the root to the tip in a smooth arc shape, forming a smooth and continuous transition arc blade. The arc blade effectively disperses stress and extends the service life of the scissors.

[0010] Its beneficial effects are as follows: the above three different blade narrowing technology solutions can be applied to different usage scenarios, which significantly enhances the applicability and practicality of this utility model in actual application and can meet diverse usage needs.

[0011] Preferably, the blade narrowing method can be linear or arc-shaped on both sides, or one side of the blade can be linearly narrowed while the other side is arc-shaped, to adapt to different usage scenarios.

[0012] Preferably, the blade is straight or has a certain curvature, or it can be wavy or serrated. The advantage of this is that different blade shapes can be adapted to different usage scenarios.

[0013] Preferably, the angle between the blade and the front end of the blade body is an obtuse angle or an arc-shaped obtuse angle, which has the advantages of avoiding scratches and maintaining aesthetics.

[0014] Preferably, the angle between the top and side of the blade is a rounded corner greater than 90°, which has the advantage of preventing scratches and making it safer.

[0015] As a preferred embodiment, the style of the knife handle is not limited to this embodiment. Other design schemes may be adopted without violating the patented technical concept. The knife handle and the handle may also be designed as an integral structure. The beneficial effect is that different knife handle schemes can be adapted to different usage scenarios.

[0016] Preferably, the rivet used for connection is only one connection method. Without violating the patented technical concept, other connection methods and components such as screw and nut combination, pin shaft, etc. can also be used to achieve the connection between components.

[0017] Preferably, when the cutter head is in the open state, the cutting edges intersect at point X; when the cutter head is not narrowed, the cutting edges intersect at point X1, and the distance between points X and X1 is the increased effective cutting length relative to the state when the cutter head is not narrowed.

[0018] The novel scissors designed in this invention feature an innovative structure where the blade narrows inward from one side of the cutting edge. This not only makes the blade more compact but also significantly increases the effective cutting length of the blade when the scissors are open at the same angle. This makes the scissors more efficient and easier to operate. At the same time, it avoids the risk of cuts and injuries that could occur from excessively large scissor openings, greatly improving safety and convenience. It has high practical value and promising market application prospects. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings, so that the advantages and features of this utility model can be more easily understood by those skilled in the art, thereby making a clearer and more explicit definition of the scope of protection of this utility model.

[0032] See attached document Figure 1 To be continued Figure 10 This utility model discloses a novel pair of scissors, comprising: blades A and B, blades C and D, handles E and F, shanks E1 and F1, and rivets G. Blades C and D are interlocked and fixedly connected by rivets G. The front ends of blades C and D form blades A and B, and the rear ends form handles E and F. One end of handle E and F is embedded in handle E1 and F1. Blades A and B begin at the connection point between the blades A1 and B1 and the blades C and D, narrowing towards the Z-axis of the blades C and D, i.e., narrowing from the side of the blades A1 and B1 towards the Z-axis of the blades C and D. The narrowing can be linear or curved. Details are as follows:

[0033] See attached document Figure 1 To be continued Figure 4 As shown, in Scheme 1: the widths of the blades A and B are narrowed synchronously, and the widths of the blades are consistent after narrowing. The range of the narrowing width value b at the root of the blades A and B is 1 / 8 to less than 1 / 2 of the width value x at the front end of the blades C and D, that is, 1 / 8 ≤ b < 1 / 2.

[0034] See attached document Figure 5 To be continued Figure 6 As shown, in Scheme 2: the widths of the blades A and B are narrowed simultaneously, with the narrowing width value c at the root of one blade being greater than the narrowing width value d at the root of the other blade, i.e., c > d. At the same time, the sum of the narrowing width values ​​c and d is less than the width value x at the front end of the blade.

[0035] See attached document Figure 7 To be continued Figure 8 As shown, in Scheme 3: the width of the cutter heads A and B is narrowed only on one side. The narrowing width value e at the root of the cutter head on the narrowed side is 1 / 3 to 2 / 3 of the width value x at the front end of the cutter body, that is, 1 / 3≤ e≤ 2 / 3. The width at the root of the cutter head on the other side is the same as the width x at the front end of the cutter body.

[0036] Of the three methods above, when linear narrowing is used, the narrowing width of the blade is uniform and the blade edge is straight; when arc narrowing is used, the blade edge gradually narrows from the root to the tip in a smooth arc shape, forming a smooth and continuous transitional arc blade edge.

[0037] See attached document Figure 10 As shown, the narrowing method of the cutter heads A and B can be linear or arc-shaped on both sides, or one side of the cutter head can be linearly narrowed while the other side is arc-shaped. For example, see attached... Figure 10 The examples are as follows: Example 1 uses double-sided linear narrowing, Example 2 uses one side linear narrowing and the other side arc narrowing, and Example 3 uses double-sided arc narrowing.

[0038] See attached document Figure 1 To be continued Figure 10 As shown, the blades A1 and B1 are straight or have a certain curvature, and may also be wavy or serrated.

[0039] See attached document Figure 4 As shown, the angle α between the blades A1 and B1 and the front ends of the blade body C and D is an obtuse angle or an arc-shaped obtuse angle, ensuring a neat and aesthetically pleasing angle at the narrowing point.

[0040] See attached document Figure 4 As shown, the angle β between the top and side of the blade C and D is a rounded corner greater than 90°. The rounded design avoids contact and is safer.

[0041] See attached document Figure 1 To be continued Figure 10 As shown, the style of the knife handles E1 and F1 is not limited to this embodiment. Other design schemes may be adopted without violating the patented technical concept. The knife handles E1 and F1 and the knife handles E and F may also be designed as an integral structure.

[0042] See attached document Figure 1 To be continued Figure 10 As shown, the rivet G used for connection is only one type of connection method. Without violating the patented technical concept, other connection methods and components such as screw and nut combinations and pins can also be used to achieve the connection between components.

[0043] See attached document Figure 9 As shown, when the cutter head is open, the blades cross at X, while when the cutter head is not narrowed, the blades cross at X1. The length between X and X1 is the increased effective cutting length relative to the state when the cutter head is not narrowed.
