Safety nail scissors structure with shear body of non-identical blade length

This creation is about safety nail scissors, especially a safety nail clipper that cuts the length of the upper and lower cutting edges of the body.

Generally speaking, "nail" is a layer of hard material that is hardened by the stratum corneum of the skin. Its main functions include: protecting the distal abdomen from damage, enhancing the sensitivity of finger touch, assisting fingers, pinching, squeezing, etc. Referring to Fig. 1, the main body of the nail is called a nail body A1, which is mainly formed by layered keratin. The root of the nail body A1 is called a half moon, and is called a half moon. And the texture is softer than the rest of the nail body A1, and the skin tissue closely connected to the bottom of the nail body A1 is called a nail bed, and a small amount of skin is left and right on the left and right sides of the nail body A1. The covered part is called the side edge A2. In addition, the top of the nail body A1 is separated from the nail bed by the free edge A11, and the nail body A1 which is separated from the nail bed and separated from the nail bed is called the front A3. .

Please refer to Figure 1. Since the nail body A1 gradually grows naturally over time, the length of the front A3 is also increased. Therefore, when the length of the front A3 is too long, the front A3 usually Naturally curved, so that the skin between the front A3 and the adjacent free edge A11 is tight, causing the gap between the fingers (ie, the position between the front A3 and the free edge A11) is not easily cleaned, causing easy contamination between them. The smudge causes the bacteria in the environment to multiply in the nails. If people grab the food directly with their fingers, they will bring along the bacteria between the nails. Ingestion, which makes people feel uncomfortable, in addition, when the length of A3 before A3 is too long, it may cause people to accidentally scratch themselves or others during exercise or work, and even the wound is infected with bacteria, so In order to avoid the aforementioned problems, nail clippers are often used to trim the length of the nail (ie, front A3).

However, as shown in Figure 1, when people trim the nails, most of the following problems occur: (1) due to the position of the front side A2 adjacent to the side A2, because it is closer to the skin and free edge A11, so if the user does not pay attention to the position of the blade of the nail clipper during the trimming process, the edge of the edge of the nail clipper will be easily cut to the skin, or the inner edge of the free edge A11 will be scratched, causing the use of the nail bed. Inconvenience; and (2) In addition, when people trim their nails, they usually push the skin under the nail scissors, but because the skin itself has elasticity, when the lower blade pushes against the skin, it is adjacent to the lower edge. The skin at the edge of the blade tends to extend to the edge of the lower blade due to its own elasticity. At this time, when the upper and lower edges of the nail clip are engaged, the upper blade will be cut into the same direction. The skin between the blades causes bleeding.

In summary, the existing nail clippers still have a lack of use, which affects the convenience of the user to trim the nails. Therefore, how to design a brand new nail clipper structure can be favored by the user, that is, become the present Creation is an important topic to be explored here.

In view of the fact that the structure of the traditional nail scissors is still not perfect, the creator has finally worked hard to study and experiment, and finally developed a safe nail clipper structure with a cutting body of different lengths for the user. Can be quickly and easily with the nail clipper The nails are trimmed and there is no need to worry about inadvertently cutting the skin on the nails.

One of the purposes of the present invention is to provide a safety nail clip structure having a shear body having a different blade length, comprising a shear body, a pivot and a force applying portion, wherein the shear body comprises an upper shear body And a cutting body, wherein the upper cutting body is provided with an upper cutting edge, and the lower cutting body is provided with a lower cutting edge at the front end, the upper cutting edge has a length smaller than the length of the lower cutting edge, and is separated from each other by a first spacing. The upper shear body is integrated with the rear shear body rear end to form the shear body; the pivot system is assembled to the shear body adjacent to the cutting edge, and penetrates the upper shear body and the lower shear a body, wherein a bottom edge of the pivot body abuts against a bottom surface of the lower shear body, the top end of the pivot shaft is exposed on a top surface of the upper shear body; the front end of the force applying portion is tied to the upper shear body a top surface thereof and pivoted to a position adjacent to the top end of the pivot shaft and rotatable relative to the pivot or the shear body, the rear end of the force applying portion being rotated to be spaced apart from the rear end of the shearing body by a second In the state of the spacing, the rear end of the urging portion is under stress and is down At the front end of the urging portion, a force is applied to the upper shear body to abut the upper shear body against the cutting edge of the lower shear body; thus, when the user trims the nail with the safety nail clip, The length of the lower blade is long, so that the skin adjacent to the free edge of the nail can be largely pushed in, so that the upper blade can extend and cut the nail, effectively preventing the edge of the upper blade from being scratched or scratched.

The present invention is a safety nail clipper structure having a shearing body having a different blade length. In an embodiment, please refer to FIG. 2, for convenience of explanation, the upper part of FIG. 2 is above the component, The bottom of the figure is below the component, the upper left of the second figure is the left side of the component, the lower right of the second figure is the right side of the component, and the lower left of the second figure is the front of the component, the upper right of the second figure. In addition to the component, the safety nail clip 1 includes a cutting body 11, a pivot 13 and a force applying portion 15, which is particularly mentioned here, and FIG. 2 only shows the basic of the safety nail clipper 1. Architecture, however, those skilled in the art of creation can familiarize themselves with the overall technical characteristics of the creation and can produce or design the requirements, and change the structure and appearance of the safety nail scissors 1 to make it clear.

Referring to FIGS. 2 and 3, the shearing body 11 includes an upper shearing body 111 and a lower shearing body 113. In this embodiment, the upper shearing body 111 and the lower shearing body 113 are made of a metal material. The upper end of the upper shearing body 111 is provided with an upper cutting edge 112, and the lower cutting end 113 is provided with a lower cutting edge 114. The length of the upper cutting edge 112 is smaller than the length of the lower cutting edge 114, so that the upper cutting edge 112 is about The upper side corresponds to the middle section of the lower cutting edge 114 (as shown in FIG. 3), and the upper cutting edge 112 and the lower cutting edge 114 are separated from each other by a first distance L1, and the upper cutting body 111 and the lower cutting body After the 113, the end portions are integrated to form the shearing body 11. Further, when the front end of the upper shearing body 111 is subjected to a force, its own elasticity will force the deformation thereof, so that the upper cutting edge 112 and the lower cutting edge 114 can Abutting each other, and when the front end of the upper shearing body 111 is no longer stressed, its own restoring force returns it to the original position, and the upper cutting edge 112 and the lower cutting edge 114 are separated from each other. A spacing L1.

In addition, as shown in FIGS. 2 and 3, the pivot 13 is assembled to the shearing body 11 adjacent to the position of the upper cutting edge 112 and the lower cutting edge 114, and the pivot 13 is sequentially passed through. The upper shear body 111 and the lower shear body 113, and the bottom edge thereof abuts against the bottom surface of the lower shear body 113, and the top end of the pivot shaft 13 is exposed on the top surface of the upper shear body 111, wherein When the front end of the upper shear body 111 is subjected to a force, it can be reciprocally displaced up and down along the pivot shaft 13 so that the blades 112, 114 can abut or separate from each other.

Referring to FIGS. 2 and 3, in the embodiment, the front end of the urging portion 15 is located on the top surface of the upper shear body 111, wherein a groove 150 is recessed in the front end of the urging portion 15. The pivot 13 can be received in the channel 150, and a rod 151 can penetrate the front end of the urging portion 15, the channel 150 and the pivot 13, so that the front end of the urging portion 15 can be pivotally connected to the pivot The position of the shaft 13 is adjacent to the top end. Further, after the user holds the rear end of the urging portion 15, the urging portion 15 can be rotated relative to the pivot shaft 13 or the shearing body 11. For example, the urging portion 15 can The position of the pivot shaft 13 is horizontally rotated, or can be vertically reversed at the position of the rod body 151, and when the rear end of the urging portion 15 is rotated to be spaced apart from the rear end of the shearing body 11 by a second distance L2, When the rear end of the urging portion 15 is biased such that the urging portion 15 is forced and displaced downward, the front end of the urging portion 15 applies a force to the upper shearing body, so that the upper cutting edge 112 and the lower cutting edge 114 is abutted to be able to cut the user's nails, but in other embodiments of the present creation, the operator can The assembly relationship or the state between the urging portion 15 and the pivot 13 is changed as long as the front end of the urging portion 15 is rotatable relative to the pivot 13 or the shearing body 11, that is, the urging portion 15 of the present invention The connection relationship between the pivots 13 is first described.

Furthermore, as shown in Figures 1 and 2, when the user uses the safety nail clip 1 to trim the nail (i.e., front A3), the lower cutting edge 114 will abut the skin adjacent to the front A3. Because the lower blade 114 has a long length, it can push the skin adjacent to the side edge A2 or the free edge A11 substantially. At this time, the front A3 adjacent to the side edge A2 can reach the skin. The first distance L1 between the upper cutting edge 112 and the lower cutting edge 114 enables the upper cutting edge 112 and the lower cutting edge 114 to cut the front A3 of the position, and the skin pushed by the lower cutting edge 114 is approximately the same. The length of the blade 114 is longer than the lower blade 114. Therefore, the user can not only adjust the position of the upper blade 112 to trim the nail adjacent to the side edge A2 (ie, front A3). And the position of the upper cutting edge 112 adjacent to the left and right side edges, there is a distance from the position of the lower cutting edge 114 adjacent to the left and right side edges (as shown by the dashed box in FIG. 3), so when adjacent to the lower cutting edge When the skin of the edge of the 114 is elastic and protrudes to the edge of the lower blade 114, the upper blade 112 does not cut the skin to the aforementioned position, and the edge of the upper blade 112 is effectively prevented from being scratched or scratched.

In summary, the overall structure of the safety nail clip 1 of the present invention is as shown in FIGS. 1 and 2, since the length of the upper cutting edge 112 is smaller than the length of the lower cutting edge 114, the cutting edges 112, 114 are formed. The cutting length is shorter than the skin area pushed by the lower cutting edge 114. For a thicker skin of the finger or toe, it is indeed possible to avoid being accidentally caught by the edge of the lower cutting edge 114. The problem of injury is cut to provide a better user experience. In addition, when the lower blade 114 pushes against the skin adjacent to the side edge A2 or the free edge A11, the upper blade 112 does not block the use. The user's line of sight allows the user to easily and quickly view the position and length of the front A3, so that the position of the upper cutting edge 112 can be appropriately adjusted to reliably cut the nail and avoid damage to the skin. The safety nail clipper 1 is obviously safer than the conventional nail clipper. According to the above, it is only a preferred embodiment of the present invention, but the scope of rights claimed by the present invention is not limited thereto. Anyone who is familiar with the art, according to the technical content disclosed in this creation, can easily think of the equivalent changes, all should not fall within the protection scope of this creation.
