Abstract
The present application relates to a scissors capable of cutting not only fingernails but also toenails, and more particularly, capable of making a person having difficulty in bending easily cut toenails and accurately cutting off toenails at this time, and capable of preventing movement at the time of operation of a fixing lever and an actuating lever for actuating an operating part of a blade part, thereby enabling induction of accurate actuation.
Description
Technical Field
The present application relates to a scissors capable of cutting not only fingernails but also toenails, and more particularly, capable of making a person who is not convenient to bend down easily cut toenails, and at this time, accurately cutting off toenails.
Background
In general, most people use scissors, which are also called nail clippers, to cut off the fingernails or toenails to a desired extent, and most of these nail clippers have a structure in which only an actuating lever is provided in a blade portion and an actuating portion, and therefore the actuating lever is rotated in a horizontal state to easily cut off the fingernails or toenails, but particularly when cutting the toenails, the user has to bend down.
However, in this case, in the state of bending over, when the actuating lever is pressed down in a state where the toenail and the toenail knife have not been kept horizontal, there arises a problem that it is difficult to accurately shear off the toenail due to the misalignment of the blade portion, and therefore it is most required to keep the toenail and the toenail knife in a state of bending over as much as possible.
However, in this case, it is not easy for a person with a thick waist or a difficulty in bending over and a person with a large belly to bend over in such a state, and therefore, it is very inconvenient to cut the toenail.
Accordingly, the present inventors have recently registered an application which proposes a toenail knife as follows: actuation of the blade portion and the operation portion constituted by the fixing lever and the actuation lever is performed in directions orthogonal to each other, that is, on the upper side of the blade portion actuated in a horizontal state in which actuation of the blade portion is induced, so that toenail can be cut off without bending down.
However, this structure has the following disadvantages: since the operation section is composed of a fixing lever that is pressed against the upper surface of the blade section and an actuating lever that is pressed and actuated on the upper side of the fixing lever, when the blade section is actuated by pressing while the fixing lever is pressed against the upper surface of the fixing lever, the fixing lever is moved on the upper surface of the blade section due to a minute gap or the actuating lever is moved on the fixing lever, and thus accurate actuation of the blade section cannot be ensured.
In addition, since these components are all formed by metal working, the fixing lever and the actuating lever are respectively constituted by a head portion and a vertical lever bent from the head portion to be vertical, when the vertical lever of the actuating lever is pressed, accurate actuation cannot be ensured due to the plurality of movable points as described above, and when stainless steel plates are used, that is, when these fixing lever and actuating lever are thin plate materials, bending occurs to fail to ensure actuation of the blade portion, and when thick plate materials are used, there are not only processing difficulties but also reduced easiness of assembly.
Disclosure of Invention
Problems to be solved by the application
Therefore, in the present application, the operation portion is injection molded with plastic to provide a thickness capable of preventing bending, while realizing a low weight, and when the blade portion of the metal material and the operation portion of the plastic material are brought into close contact to be actuated, the possibility of movement can be minimized, so that actuation of the blade portion can be ensured.
Means for solving the problems
Therefore, the blade part of the present application has an opening on the upper surface thereof in a state that the rear ends of the opened blades are connected in a bending manner, thereby not only preventing the movement of the shaft pin and the fixing rod, but also minimizing the stress generated when the blade part is repeatedly folded, and simultaneously maintaining the elastic restoring force, the head of the fixing rod is closely attached to the upper surface having the opening, the upper surface of the head of the fixing rod is provided with a plurality of actuating pins which are spaced left and right, so that the actuating rod is prevented from fine movement when being folded in a state that the actuating rod is closely attached, and the upper surface of the corresponding head of the fixing rod is provided with an actuating groove.
The fixing rod has a plurality of support pins spaced from the bottom surface of the head portion, so that the support pins can be closely attached to the inner wall of the opening of the blade portion to prevent the fixing rod from moving.
In order to prevent the fixing rod from moving and becoming more firm, the upper surface of the blade part is provided with a plurality of protrusions, and the bottom surface of the head part of the fixing rod is provided with a groove part for tightly fixing the protrusions, thereby preventing sinking holes generated during injection molding due to inclined surfaces, wherein the inclined surfaces are provided for preventing the vertical rod of the fixing rod from bending when the actuating rod is pressed.
Effects of the application
Therefore, the present application has an effect that the toenail can be cut without bending down, and when the toenail is actuated by the combination of the blade part made of a metal material and the operation part of injection molding, not only the accurate actuation can be induced, but also the toenail can be provided to a required person at a low price, and in addition, even if the fixing lever and the actuation lever of the operation part are repeatedly operated, the accurate actuation can be induced from beginning to end, and the fingernail and the toenail can be easily managed.
