Description

Technical Field

[0001] This application relates to the field of yarn cutters, and in particular to a yarn cutter with an inner fold. Background Technology

[0002] The descriptions in this section are provided for background information related to this disclosure only and do not constitute prior art. Yarn shears are primarily used for cutting yarn. Yarn shears mainly consist of two hinged handles and blades, with the blades fixedly installed in the U-shaped grooves of the handles.

[0003] See Figure 6 In related technologies, the thickness of the blade mounting part of the handle is 2.8-3.3mm. The side wall surface of this part is relatively small and is usually smooth. When the fingers press the handle, the contact area of ​​the fingers is small, the pressure is large, and it is easy to slip, resulting in a poor user experience of the yarn shears. Summary of the Invention

[0004] In view of this, this application provides a yarn shear with an inner fold, which can improve the stability and comfort of holding and also improve assembly efficiency.

[0005] To achieve the above objectives, this application employs the following technical solution:

[0006] A yarn shear with inner folds, characterized in that: it includes two handles and two blades respectively mounted on the handles; the lower ends of the two handles are hinged to each other; the upper end of the handle has a mounting part for mounting the blades; the mounting part has a mounting groove with openings inward and upward; the distance L between the outer surfaces of the front and rear sides of the mounting part is 4.5-5.2mm; the outer wall of the mounting part has anti-slip texture; and two inner folds are integrally connected to the front and rear sides of the mounting part, the inner folds are bent from the inner opening of the mounting groove into the mounting groove; and the blades are fixedly mounted between the two inner folds.

[0007] The yarn shears with inner folds described in this application increase the width of the outer wall of the mounting part and provide anti-slip texture on the outer wall, thereby increasing the contact area and friction to improve the stability and comfort of holding. In addition, two inner folds are provided in the mounting groove to compensate for the gap between the mounting groove wall and the blade caused by the widening of the outer wall, so that there is no need to add a shim in the mounting groove, thereby improving the assembly efficiency of the yarn shears.

[0008] In some embodiments, the anti-slip texture is a plurality of recessed small holes.

[0009] In some embodiments, the outer wall of the blade is provided with anti-slip teeth that are continuous with the anti-slip texture, and the anti-slip teeth are arranged in alternating concave and convex patterns. When some users use the blade, their fingers will come into contact with the outer wall of the blade. By adding anti-slip teeth, the friction can be increased, thereby improving the stability and comfort of the grip.

[0010] In some embodiments, the inner side of the lower end of the handle is provided with alternating concave and convex decorative teeth. These decorative teeth enhance the aesthetics of the yarn shears and visually make the area appear fuller.

[0011] In some implementations, the lower ends of the two handles are hinged together by a hinge shaft, and the blade is riveted to the mounting portion.

[0012] In some embodiments, the handle is a U-shaped handle.

[0013] In some embodiments, the handle is also fixedly provided with an anti-disengagement hook, and the two anti-disengagement hooks of the two handles are hooked together to limit the opening angle of the handle.

[0014] In some embodiments, the inner flap has a protrusion that extends forward and backward, the protrusion being used to hold the inner side of the blade in place, thereby limiting the blade's lateral displacement. The protrusion encloses the blade, making blade installation easier.

[0015] In some embodiments, V-fold portions are provided at both ends of the inner flap, and one end of the inner flap is integrally connected to the mounting portion through the V-fold portion. The V-fold portion can be folded and compressed under pressure. The V-fold portion is a foldable and compressible part, which allows for the assembly of blades of different thicknesses, thus increasing flexibility and applicability.

[0016] As can be seen from the above technical solution, this application has at least the following advantages and positive effects:

[0017] This application discloses a yarn shear with inner folds. By increasing the width of the outer wall of the mounting part and setting anti-slip texture on the outer wall, the contact area and friction can be increased, thereby improving the stability and comfort of holding. Furthermore, two inner folds are set in the mounting groove to compensate for the indirect effect of widening the outer wall, thus eliminating the need to add shims in the mounting groove and improving the assembly efficiency of the yarn shear.

[0025] To make the objectives, technical solutions, and advantages of this application clearer, the application will be described in further detail below with reference to the accompanying drawings. The terminology used in the embodiments section of this application is only for explaining specific embodiments and is not intended to limit the application.

[0026] See Figures 1 to 5 A yarn shear with inner folds includes two handles 1 and two blades 2 respectively mounted on the handles 1. The lower ends of the two handles 1 are hinged to each other, and the upper end of the handles 1 has a mounting part 11 for mounting the blades 2. The mounting part 11 has a mounting groove 12 with openings inward and upward. The distance L between the outer surfaces of the front and rear sides of the mounting part 11 is 4.5-5.2 mm. The outer side wall of the mounting part 11 is provided with anti-slip texture 13. Two inner folds 14 are integrally connected to the front and rear sides of the mounting part 11 respectively. The inner folds 14 are bent into the mounting groove 12 from the inner opening of the mounting groove 12. The blades 2 are fixedly mounted between the two inner folds 14.

[0027] This yarn shear increases the width of the outer wall of the mounting part 11 and provides anti-slip texture 13 on the outer wall, which increases the contact area and friction to improve the stability and comfort of holding. In addition, two inner folding pieces 14 are provided in the mounting groove 12 to compensate for the indirect effect of widening the outer wall, so that there is no need to add a shim in the mounting groove 12, thereby improving the assembly efficiency of the yarn shear.

[0028] The anti-slip texture 13 consists of multiple recessed holes.

[0029] The outer wall of the blade 2 is provided with anti-slip teeth 21 that are continuous with the anti-slip texture 13. The anti-slip teeth 21 are arranged in an alternating pattern of concave and convex. When some users use the blade, their fingers will come into contact with the outer wall of the blade 2. By adding anti-slip teeth 21, the friction can be increased, thereby improving the stability and comfort of holding the blade.

[0030] The inner side of the lower end of the handle 1 is provided with alternating concave and convex decorative teeth 15. The decorative teeth 15 can increase the aesthetics of the yarn shears, and visually make the part look fuller.

[0031] The lower ends of the two handles 1 are hinged together by the hinge shaft 3, and the blade 2 is riveted to the mounting part 11.

[0032] Handle 1 is a U-shaped handle.

[0033] An anti-disengagement hook 16 is also fixedly installed on the handle 1. The two anti-disengagement hooks 16 of the two handles 1 are hooked together to limit the opening angle of the handle 1.

[0034] See Figure 4 This illustrates a second embodiment of the present application, which differs from the previous embodiment in that: the inner flap 14 is provided with a protrusion 141 protruding in the forward and backward direction. The protrusion 141 is used to hold the inner side of the blade 2, thereby limiting the left and right displacement of the blade 2. The protrusion 141 covers the blade 2, making it more convenient to install the blade 2.

[0035] See Figure 5 This describes a third embodiment of the present application, which differs from the first embodiment in that: V-fold portions 142 are respectively provided at both ends of the inner flap 14, and one end of the inner flap 14 is integrally connected to the mounting portion 11 through the V-fold portion 142. The V-fold portion 142 can be folded and compressed under pressure. The V-fold portion 142 is a foldable and compressible part, which can be used to assemble blades 2 of different thicknesses, thus providing greater flexibility and applicability.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of this application, and are not intended to limit them; although the embodiments of this application have been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
