[0002] The common yarn scissors on the market can only cut fine yarns. It is laborious and difficult to cut thick yarns, so you need to change to a larger yarn scissors. In actual operation, you need to equip two yarn scissors of different sizes. If you need to cut thicker fabrics or leather, you have to change to a pair of scissors to cut, which is very inconvenient. In actual life and application, you need multi-kinetic and easy-to-operate yarn scissors to cut thick and thin yarns and daily fabrics and leathers, to replace large and bulky scissors, and facilitate our lives.

[0003] Existing yarn shears generally have two thin blades, which are fixed by metal or plastic handles, and opened by springs or plastic handles after cutting. The blades are relatively thin, and the combination of the blades and the handles will change the cutting angles of the two blades when cutting thicker fabrics or thicker threads, making the blades inconsistent in grinding angle, making the blades easily blunt and difficult to cut.

Wherein, the function of the limiting pin 6 and the limiting hole 24 is to limit the opening and closing angles of the two blades.

[0026] The first blade 2 has a first blade pad 21 at one end away from the blade edge, and the second blade 3 has a second blade pad 31 at one end away from the blade edge. The first blade pad 21 and the second blade pad 31 are in face-to-face contact with each other. The first blade pad 21 and the second blade pad 31 are used to make the blade edges of the two blades fit better.

[0027] Among them, a first blade mounting screw hole 22 is opened in the middle part of the first blade 2, and a first set screw hole corresponding to the first blade mounting screw hole 22 is set on the first blade mounting part 8. The middle part of the first blade 2 can be detachably mounted on the first blade mounting part 8 through the threaded cooperation of the first mounting screw 4 with the first blade mounting screw hole 22 and the first set screw hole.

[0028] Among them, a second blade mounting screw hole 32 is opened in the middle part of the second blade 3, and a second set screw hole corresponding to the second blade mounting screw hole 32 is provided on the second blade mounting part 9. The middle part of the second blade 3 can be detachably mounted on the second blade mounting part 9 through the threaded cooperation of the second mounting screw 5 with the second blade mounting screw hole 32 and the second set screw hole.

[0029] A first blade through hole 23 is formed at one end of the first blade 2 away from the blade, and a second blade through hole 33 is formed at one end of the second blade 3 away from the blade.

[0030] Among them, the hinge assembly 7 is a screw set, which includes a step nut 71 and a matching assembly screw 72. The step nut 71 passes through the first blade through hole 23 and the second blade through hole 33 and is threadedly connected to the assembly screw 72.

[0032] Wherein, the pressing surface of the plastic set 1 is provided with anti-slip grooves 10 .

[0033] The thickness of the first blade and the second blade is relatively thicker than that of the existing yarn shears.

[0034] The working principle of the utility model is as follows: the concept of scissors is applied to yarn shears, the handles of existing scissors are removed, and the scissor blades, namely the first blade and the second blade of the utility model, are retained. Such a structure well overcomes the disadvantage that the shearing angles of the two blades of the existing yarn shears are easy to change. When shearing, the stability of the existing blade angle is controlled by the handle connected to the blades, and now the first blade and the second blade themselves are fixed and controlled by rivets or screw sets, which has stronger stability and smoother shearing. The thickness of the blade can also be appropriately thickened to increase the stability during shearing. The addition of a plastic kit can increase the comfort of the grip. At the same time, the plastic kit is elastic and has moderate elasticity when opened after shearing, so that it can be used with smooth shearing and comfortable grip, and can easily shear thick and thin yarns, cloth and The leather material, the limit pin and the limit hole function to limit the opening and closing angles of the two blades, and the two cushion layers function to make the cutting edges of the two blades fit better; in terms of assembly, traditional yarn shears require certain skills to assemble, and require a master to assemble, which increases the cost and is not easy to assemble in batches and stably. The first blade and the second blade of the utility model are fixed and controlled by rivets or screw sets, and the first blade and the second blade are connected to the plastic kit by simple screws. At the same time, the first blade and the second blade are limited by limit pins. Assembly and disassembly are simple and convenient, which greatly reduces the difficulty of assembly. General workers can easily complete the assembly, and batches can be assembled stably. Later, the assembly can be completely completed automatically by CNC machines, which reduces the assembly cost and increases the stability of batch production.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents. Anything not described in detail in the utility model is a well-known technology of those skilled in the art.
