Description

A wire saw tool with an adjustable leather pull ring Technical Field

[0001] This utility model belongs to the field of manual tool technology, specifically a wire saw tool with an adjustable leather pull ring. Background Technology

[0002] Wire saws, as common cutting devices, are widely used in wood processing, stone cutting, and other precision processing of materials. In practice, the efficiency and ease of use of wire saws directly impact user experience and work efficiency. Traditional wire saws are typically equipped with a fixed leather sheath pull ring for grip and operation. However, existing sheath pull ring designs have significant shortcomings; their fixing structure cannot be adjusted according to the user's hand size or operating habits, leading to hand fatigue and even affecting operational accuracy during prolonged use. Furthermore, existing sheath pull rings are cumbersome to install and remove, failing to meet the need for rapid adjustments in different scenarios. These problems not only reduce the applicability and flexibility of wire saws but also limit their performance in high-efficiency working environments. Therefore, developing a wire saw with an adjustable sheath pull ring to improve operating comfort and adaptability while simplifying installation and adjustment has become an urgent technical challenge. Summary of the Invention

[0003] This invention addresses the shortcomings of existing wire saw tools in terms of portability, operational flexibility, and versatility of application scenarios by proposing a wire saw tool with an adjustable leather pull ring. This tool achieves its technical goals of simple structure, convenient operation, and adaptability to various usage needs through optimized main structural design, the introduction of an ergonomic red plastic handle, and the use of a transparent plastic packaging bag for protection.

[0004] This utility model provides a wire saw tool with an adjustable leather pull ring, including a wire saw body, a red plastic handle, and a transparent plastic packaging bag. The wire saw body is made of metal wire, which is spirally wound with a diameter ranging from 1.0 mm to 2.0 mm and a pitch of 3.0 mm to 5.0 mm to ensure both hardness and toughness during cutting. The metal wire is made of high-carbon steel or stainless steel and is surface polished to a roughness Ra value controlled below 0.4 micrometers, thereby avoiding damage to the user's hands or the material being cut during use. Furthermore, the wire saw body has a fixed end ring and an adjusting end ring at both ends, where the fixed end ring is used to connect one red plastic handle, and the adjusting end ring is used to connect the other red plastic handle and realize the tension adjustment function.

[0005] Furthermore, the red plastic handle is injection molded from polypropylene material with a Shore hardness range of 70D to 80D, ensuring a certain degree of softness and anti-slip performance when gripped. The outer surface of the handle is designed with arc-shaped grooves, with a depth of 1.5 mm to 2.5 mm and a width of 8 mm to 12 mm, to match the grip posture of fingers in a natural bending state. Specifically, the end of the handle has a circular through-hole with a diameter of 5 mm for threading a metal wire and fixing it using a hot-melt process, ensuring a connection strength of over 100 Newtons. In addition, the handle is colored with Pantone color code 186C red, which not only facilitates identification but also enhances the product's visual appeal.

[0006] Furthermore, the transparent plastic packaging bag is made of polyethylene material with a thickness ranging from 0.1 mm to 0.2 mm and a transparency of not less than 90% to ensure that the internal wire saw tools are clearly visible. The opening of the packaging bag is equipped with a self-sealing strip structure with a width of 5 mm and a tooth engagement tightness of more than 20 teeth per centimeter, thereby enabling repeated opening and closing. Specifically, the inside of the packaging bag is coated with an antistatic coating with a thickness of 10 to 20 micrometers to prevent the wire saw body from attracting dust particles due to static electricity, which could affect its cutting performance. Furthermore, the size of the packaging bag is determined according to the length and width of the wire saw tools, with a gap of at least 5 mm reserved to avoid severe friction of the wire saw body inside the packaging bag.

[0007] In this invention, the operation of the wire saw tool is achieved through the following steps: S1, remove the wire saw body from the transparent plastic packaging bag; S2, hold the two red plastic handles with both hands and adjust the tension of the wire saw body; S3, place the wire saw body on the surface of the material to be cut and apply appropriate pressure to perform reciprocating motion to complete the cutting task. The tension adjustment is achieved by pulling the adjustment end ring, and the adjustment range is 1% to 5% of the original length of the wire saw body to adapt to cutting materials of different thicknesses and hardnesses.

[0008] Specifically, this utility model incorporates a spiral winding structure in the design of the wire saw body. The technical solution is as follows: the spiral axis of the metal wire coincides with the central axis of the wire saw body, with 20 to 30 spiral turns and a gap of 0.5 mm to 1.0 mm between adjacent spiral turns. This structural design not only improves the bending resistance of the wire saw body but also increases the cutting contact area, resulting in an approximately 30% increase in cutting efficiency. Furthermore, the spiral winding structure generates a slight vibration effect during cutting, which helps reduce cutting resistance and extend service life.

[0009] The beneficial effects of this invention are as follows: by optimizing the spiral winding structure design of the wire saw body, cutting efficiency and durability are significantly improved; by introducing an ergonomically designed red plastic handle, user grip comfort is improved and operational fatigue is reduced; and by using a transparent plastic packaging bag for protection, the wire saw tool is effectively protected from the influence of the external environment during transportation and storage. Furthermore, the overall weight of this wire saw tool is no more than 200 grams, its compact size makes it easy to carry, and it meets the needs of various scenarios such as outdoor activities, emergency survival, and handicrafts.

[0010] Furthermore, the technical solution of this utility model also has high versatility and scalability. For example, the wire saw body can be made of different metal materials and surface treatment processes according to actual needs to adapt to specific cutting requirements. The shape and size of the red plastic handle can also be adjusted according to user feedback to further optimize the grip experience. In addition, the transparent plastic packaging bag can also integrate QR code labels or product information card slots to facilitate users in obtaining more usage guidance and maintenance suggestions.

[0011] In summary, this utility model, through a series of innovative designs and technological improvements, provides a highly portable, easy-to-operate, and versatile wire saw tool. The tool not only solves the problems existing in the prior art but also demonstrates its advantages in practical applications through its specific implementation, possessing broad application prospects and market value.

[0017] This utility model provides a wire saw tool with an adjustable leather pull ring, and its specific implementation is described in detail with reference to Figures 1 to 3. The wire saw tool includes a wire saw body 1, a red plastic handle 2, and a transparent plastic packaging bag 3. The specific structure and function of each component will be described one by one in the following content, and the operating principle and operation process will be fully described in conjunction with actual application scenarios.

[0018] The wire saw body 1 is the core component of this invention, made of metal wire 4. The material is selected from high-carbon steel or stainless steel, and after surface polishing, the roughness Ra value is controlled below 0.4 micrometers, effectively avoiding scratches or material damage caused by surface roughness during use. As shown in Figure 2, the metal wire 4 is spirally wound, with a diameter ranging from 1.0 mm to 2.0 mm and a pitch from 3.0 mm to 5.0 mm. This design not only ensures a balance between hardness and toughness in the wire saw body 1 during cutting, but also improves bending resistance by aligning the spiral axis with the central axis of the wire saw body. The number of spiral turns is set to 20 to 30, with a gap of 0.5 mm to 1.0 mm between adjacent spiral turns. This structure significantly increases the cutting contact area, improving cutting efficiency by approximately 30%. Furthermore, the spiral winding structure generates a slight vibration effect during cutting, helping to reduce cutting resistance and extend service life. The main body 1 of the wire saw has a fixed end ring 5 and an adjusting end ring 6 at each end. The fixed end ring 5 is used to connect a red plastic handle 2, while the adjusting end ring 6 is used to connect another red plastic handle 2 and realize the tension adjustment function. The tension is adjusted by pulling the adjusting end ring 6, and the adjustment range is 1% to 5% of the original length of the wire saw body to adapt to cutting materials of different thicknesses and hardnesses. For example, when cutting wood, the user can adjust the tension of the wire saw body according to the hardness of the wood, thereby ensuring the stability and efficiency of the cutting process.

[0019] The red plastic handle 2 is injection molded from polypropylene material with a Shore hardness range of 70D to 80D, providing a degree of softness and anti-slip properties, significantly improving the user's grip experience. As shown in Figure 1, the outer surface of the red plastic handle 2 features an arc-shaped groove 7, with a depth of 1.5 mm to 2.5 mm and a width of 8 mm to 12 mm. The design of the arc-shaped groove 7 fully considers ergonomic principles, matching the grip posture of fingers in a natural bending state, thereby reducing fatigue caused by prolonged operation. The end of the red plastic handle 2 has a circular through hole 8 with a diameter of 5 mm for threading a metal wire 4 and fixing it through a hot-melt process, ensuring a connection strength of over 100 Newtons. In addition, the red plastic handle 2 is colored with Pantone color code 186C. This color is not only easy to identify but also enhances the visual appeal of the product. Especially in outdoor activities or emergency survival scenarios, the bright red can quickly attract attention, making it easier for users to find the tool quickly.

[0020] The transparent plastic packaging bag 3 is made of polyethylene material with a thickness ranging from 0.1 mm to 0.2 mm and a transparency of not less than 90%, as shown in Figure 3. The design of the transparent plastic packaging bag 3 ensures that the internal wire saw tool is clearly visible. A self-sealing strip structure 9 is provided at the opening of the packaging bag. The self-sealing strip is 5 mm wide and has a tooth tightness of more than 20 teeth per centimeter. This design allows for repeated opening and closing, facilitating multiple uses of the wire saw tool without affecting the sealing effect. The inside of the transparent plastic packaging bag 3 is coated with an antistatic coating 10 with a thickness of 10 to 20 micrometers. This coating prevents the wire saw body 1 from being affected by dust particles attracted by static electricity, thus protecting its cutting performance. The size of the packaging bag is determined according to the length and width of the wire saw tool, with a gap of at least 5 mm reserved to avoid severe friction of the wire saw body 1 inside the packaging bag, thereby protecting the tool surface from damage.

[0021] The operation of the wire saw tool is as follows: S1, remove the wire saw body 1 from the transparent plastic packaging bag 3; S2, hold the two red plastic handles 2 with both hands and adjust the tension of the wire saw body 1; S3, place the wire saw body 1 on the surface of the material to be cut and apply appropriate pressure to perform a reciprocating motion to complete the cutting task. In practical applications, this wire saw tool is suitable for various scenarios, such as tree branch trimming in outdoor activities, rope cutting in emergency survival, and cutting model materials in handicrafts. Taking outdoor activities as an example, when a user needs to trim a tree branch, they can first take the wire saw tool out of the transparent plastic packaging bag 3, and then adjust the tension of the wire saw body 1 by pulling the adjusting end ring 6 to adapt it to the hardness of the branch. Then, place the wire saw body 1 on the surface of the branch, hold the red plastic handles 2 with both hands and apply appropriate pressure, and complete the cutting task through reciprocating motion. Because the wire saw body 1 adopts a spiral winding structure, the slight vibration effect generated during the cutting process can effectively reduce cutting resistance, thereby improving cutting efficiency and reducing user fatigue. In addition, the curved groove design of the red plastic handle 2 allows users to maintain a comfortable grip even during long-term operation, further improving the tool's practicality.

[0022] The technical solution of this utility model has high versatility and scalability. For example, the wire saw body 1 can be made of different metal materials and surface treatment processes according to actual needs to adapt to specific cutting requirements. For applications involving cutting stainless steel, high-strength stainless steel can be selected and hardened to improve the durability of the wire saw body 1. The shape and size of the red plastic handle 2 can also be adjusted based on user feedback to further optimize the grip experience. For example, for users with larger hands, the length and width of the handle can be increased, while the depth and width of the arc-shaped groove 7 can be adjusted to better fit the user's hand curve. In addition, the transparent plastic packaging bag 3 can also integrate a QR code label or product information card slot to facilitate users in obtaining more usage guidance and maintenance suggestions. For example, by printing a QR code on the surface of the packaging bag, users can scan the QR code to access the official website of the product and learn about detailed usage tutorials and maintenance methods, thereby better utilizing the function of the wire saw tool.

[0023] In summary, this utility model, through a series of innovative designs and technological improvements, provides a highly portable, easy-to-operate, and versatile wire saw tool. The spiral winding structure of the wire saw body 1 significantly improves cutting efficiency and durability; the ergonomic design of the red plastic handle 2 improves user comfort and reduces operational fatigue; and the transparent plastic packaging bag 3 effectively protects the wire saw tool from external environmental influences during transportation and storage. Weighing no more than 200 grams, its compact size makes it easy to carry, meeting the needs of various scenarios such as outdoor activities, emergency survival, and handicrafts. The technical solution of this utility model demonstrates its advantages in practical applications through specific implementation methods, possessing broad application prospects and market value.
