Abstract

The utility model relates to a pair of thread clippers, in particular to a pair of thread clippers which can be ground and is free of blade placement. The pair of thread clippers comprises a plastic handle and blades arranged at the front end of the handle, wherein the handle is of a U structure, closing buckles are arranged on the inner side of the handle, pressing faces are arranged on the back sides of the front ends of the handle, the inner side of the bottom of the U-shaped structure of the handle is of a wavy return spring structure, an inclination angle is formed between each pressing face and the plane of the corresponding blade, anti-skid lines are arranged on the surfaces of the pressing faces, and the thickness of the handle gradually decreases from the front end to the rear end. The pair of thread clippers is simple in structure, easy to operate, high in shearing capacity and long in service life, the blades can be conveniently ground, and can be repeatedly used, the width of the handle and the widths of the pressing faces are large, a user can feel comfortable when holding the thread clippers in the shearing process, the blades are formed in a one-off mode after being placed into a handle mold, the production technology is simple, the cost is low, and production efficiency is high.

Description

A kind of yarn is cut

Technical field

The utility model relates to a kind of yarn to be cut, and especially can grinding exempts from the yarn of allowing blade replacement and cuts.

Background technology

It is very high that yarn is cut in textile clothing industry frequency of utilization, is mainly used to cut off sewing thread and yarn, Bao Bu.Yarn is cut mainly and is made up of blade, spring, handle now, yarn is cut and is cut for present more conventional yarn as shown in Figure 1, this yarn is cut as all-metal material, yarn easy to hang, and handle is thinner, grasp inconvenience, handle connecting portion easily produces gap, affects cutting performance, and metal spring easily gets rusty, affect performance and reduce, and complex process.

Current yarn has been wiped out outside above-mentioned shortcoming, and part yarn is cut and also existed operation painstakingly, and handle cannot open, the difficulty of whetting a knife, and shear ability is poor, and production cost is high, and the utilization rate that yarn is cut is low.

Utility model content

For solving appeal problem, the utility model provides a kind of yarn to cut, and comprises plastic handle and the blade that is arranged on handle front end, handle is U-shaped structure, handle inner side is provided with to close buckles, and handle front end back is provided with press surface, and described handle u shape structural base inner side is waveform backspring structure.

Described press surface and blade plane intersect an inclination angle.

Described press surface surface is provided with anti-slip veins.

Described handle thickness reduces from front to back gradually.

The waveform backspring structure of the utility model handle u shape structural base inner side is than the non-corrugated longer life-span of backspring structural elasticity, also need not other assistant spring devices, and handle opening angle is larger, more than opening angle can reach 90 degree, facilitate blade grinding, blade can repeatedly be reused.Handle press surface with intersect an inclination angle to blade plane, the pressure force between blade is larger, has increased the shearing force ability that yarn is cut.The finger sliding when anti-slip veins of pressure surface can prevent from shearing.Handle thickness reduces from front to back gradually, and front end is thicker, and rigidity is larger, indeformable, and rear end is thinner, strengthens elasticity.

The utility model is simple in structure, and easily, shear ability is strong in operation, long service life, and blade facilitates grinding, can repeatedly utilize, and handle and pressure surface are wider, and shearing grasps comfortable, and blade is put one-shot forming in handle mould into, and production technology is simple, and cost is low, and the rate that comes into force is high.

Fig. 4 is that the utility model yarn is cut the schematic diagram of dehiscing.

Detailed description of the invention

Below in conjunction with accompanying drawing, by embodiment, the technical solution of the utility model is further described in detail.

The utility model is that a kind of yarn is cut, and comprises plastic handle 2 and the blade 1 that is arranged on handle front end, and handle 4 is U-shaped structure, and handle 4 inner sides are provided with to close buckles 5, and handle 4 front end backs are provided with press surface 3, and handle u shape structural base inner side is waveform backspring structure 6; Press surface becomes an inclination angle with blade plane; Press surface surface is provided with anti-slip veins 3; Handle 2 thickness reduce from front to back gradually.

In the time shearing, backspring can be subject to certain stress, and the suffered stress of corrugated backspring 6 is relatively less, longer service life; Thumb forefinger is pressed handle pressure surface 2, when pressure surface 2 becomes an inclination angle a with blade 1 plane, can be increased in the active force of vertical blades direction, and the pressure force between two blades increases, and has strengthened the shearing force that yarn is cut; Handle 4 and pressure surface 2 are wider, point suffered pressure and reduce, and can allow user grasp comfortable, and the anti-slip veins 3 of pressure surface, has and can prevent finger sliding; Handle 2 thickness reduce from front to back gradually, and front end is thicker, and rigidity is large, are more conducive to press power transmission, and rear end is thinner, and elasticity is stronger; In the time producing, only blade 1 need to be put in handle mould, single injection-molded can complete self-contained process.
