It can abut against the handle 45 of the other blade 38. When the set screw 47 is loosened and the leaf spring 46 is moved and adjusted with respect to the one handle 44, the position where the tip 46a of the leaf spring 46 abuts against the other handle 45 is shown in FIG. 8 (a) or FIG. 9 (a). Can be changed. Therefore, as shown in FIG. 8A, in the use state Q in which the handles 44 and 45 are opened to each other by the elastic force of the leaf spring 46, the separation distance H between the handles 44 and 45 and the cutting edges 41a of the both blade bodies 41 and 42 are used. , 42a can be set to a large pressable state Q1, and in the use state Q in which both handles 44, 45 are opened to each other by the elastic force of the leaf spring 46 as shown in FIG. , 45, and the pressable state Q2 in which the distance S between the blade edges 41a and 42a of both blade bodies 41 and 42 can be set small. When the handles 44 and 45 are closed against each other against the elastic force of the leaf spring 46 in the use state Q shown in FIG. 8 (a) or FIG. 9 (a), they are shown in FIG. 8 (b) or FIG. Thus, both the blade bodies 41 and 42 are also closed to each other, and the both blade edges 41a and 42a abut against each other. If the leaf spring 46 is rotated about the set screw 47 by one handle 44 and the tip end portion 46 a is separated from the other handle 45, both the handles are in a state where the elastic force of the leaf spring 46 does not act on the handle 45. 44 and 45 can be stored closed together.

In another example of the second embodiment shown in FIGS. 10 to 11, a leaf spring 46 attached to a handle 44 of one blade 37 as a restricting member by a set screw 47 is rotatable about the set screw 47. The leaf spring 46 is supported by a pair of elastic arm portions 46b, 46c having different lengths. When the leaf spring 46 is rotated around the set screw 47, one elastic arm portion 46b of the leaf spring 46 comes into contact with the other handle 45 as shown in FIG. Thus, the other elastic arm portion 46 c of the leaf spring 46 abuts against the other handle 45. Therefore, as shown in FIG. 10A, in the use state Q in which both the handles 44 and 45 are opened by the elastic force of the leaf spring 46, the separation distance H between both the handles 44 and 45 and the cutting edges 41a of the both blade bodies 41 and 42 are obtained. , 42a can be set to a large pressable state Q1, and in the use state Q in which both patterns 44, 45 are opened to each other by the elastic force of the leaf spring 46 as shown in FIG. , 45, and the pressable state Q2 in which the distance S between the blade edges 41a, 42a of both blade bodies 41, 42 can be set small. When the handles 44 and 45 are closed against each other against the elastic force of the leaf spring 46 in the use state Q shown in FIG. 10 (a) or 11 (a), they are shown in FIG. 10 (b) or FIG. 11 (b). Thus, both the blade bodies 41 and 42 are also closed to each other, and both the blade edges 41a and 42a abut against each other. Note that if the leaf spring 46 is rotated around the set screw 47 by one handle 44 and both elastic arm portions 46b and 46c are separated from the other handle 45, the elastic force of the leaf spring 46 does not act on the handle 45. In the state, both the handles 44 and 45 can be closed and stored.
本実施形態は下記の効果を有する。
* 第1実施形態においては、手のサイズや爪のサイズなどの使用者の身体的条件に応じて、使用状態Qで上刃体5に対する押圧操作てこ4の離間距離Hや上下両刃体5,6の刃先5a,6aの間隔Sを変更して、押圧操作てこ4と上刃体5との相対位置関係を互いに相違させた複数の押圧可能状態Q1,Q2にすることができるので、爪切りの使い勝手を良くすることができる。
This embodiment has the following effects.
* In the first embodiment, according to the user's physical conditions such as the hand size and the nail size, in the use state Q, the pressing operation lever 4 with respect to the upper blade body 5 is separated by the separation distance H and the upper and lower blade bodies 5, 6 can be changed to a plurality of pressable states Q1, Q2 in which the relative positional relationship between the pressing lever 4 and the upper blade body 5 is different from each other. The usability can be improved.
* 第2実施形態及びその別例においても、手のサイズや爪のサイズなどの使用者の身体的条件に応じて、使用状態Qで両柄44,45の離間距離Hや両刃体41,42の刃先41a,42aの間隔Sを変更して、両柄44,45の相対位置関係を互いに相違させた複数の押圧可能状態Q1,Q2にすることができるので、爪切りの使い勝手を良くすることができる。
* Also in the second embodiment and other examples thereof, the distance H between the handles 44 and 45 and the blades 41 and 42 in the use state Q according to the physical conditions of the user such as the hand size and the nail size. The distance S between the blade edges 41a and 42a can be changed to a plurality of pressable states Q1 and Q2 in which the relative positional relationship between the handles 44 and 45 is different from each other. Can do.
* 第1実施形態においては、回動支持部12の付近で押圧操作てこ4にある既存の圧接部8の形態を変形させるだけの簡単な構成により、使用状態Qにおける押圧可能状態Q1,Q2を複数設定することができる。
* In the first embodiment, the pressable states Q1 and Q2 in the use state Q are obtained by a simple configuration that only deforms the form of the existing press contact portion 8 in the pressing lever 4 near the rotation support portion 12. Multiple settings can be made.
* 第2実施形態及びその別例においては、両柄44,45間にある既存の板ばね46を利用するだけの簡単な構成により、使用状態Qにおける押圧可能状態Q1,Q2を複数設定することができる。
* In the second embodiment and other examples thereof, a plurality of pressable states Q1, Q2 in the use state Q are set by a simple configuration that simply uses the existing leaf spring 46 between the handles 44, 45. Can do.
* 第1実施形態においては、不使用状態Pで押圧操作てこ4の操作摘み31が上向きになるので、操作摘み31を前進位置Fまたは後退位置Rに操作し易いが、使用状態Qで操作摘み31が下向きになって上刃体5と押圧操作てこ4との間に位置するので、押圧操作てこ4の押圧時に邪魔にならない。
* In the first embodiment, since the operation knob 31 of the pressing lever 4 is upward in the non-use state P, the operation knob 31 can be easily operated to the forward position F or the reverse position R. Since 31 is located downward and is positioned between the upper blade body 5 and the pressing lever 4, it does not get in the way when the pressing lever 4 is pressed.
* 従来は手のサイズに応じて各種サイズの爪切りを使い分けることがあるが、第1実施形態や第2実施形態及びその別例においては、手のサイズが変わっても一つの爪切りだけを用意すればよい。
* 第1実施形態や第2実施形態及びその別例においては、両刃先5a,6a,41a,42aの間隔Sが大きい爪切りを手の小さい使用者例えば子供が利用すると、指先の肉を切るかもしれないという恐怖心を感じるおそれがあるが、両刃先5a,6a,41a,42aの間隔Sが小さい爪切りを利用することでそのおそれを少なくして使用者に安心感を与えることができる。また、親が子供の爪を切る場合も子供に安心感を与えることができる。
* Conventionally, different sizes of nail clippers may be used depending on the size of the hand. In the first and second embodiments and other examples, only one nail clipper is used even if the hand size changes. Just prepare.
* In the first embodiment, the second embodiment, and other examples thereof, if a user with a small hand, such as a child, uses a nail clipper with a large distance S between the two blade edges 5a, 6a, 41a, 42a, the meat of the fingertip is cut. Although there is a fear of fear that it may be, by using a nail clipper having a small interval S between the two cutting edges 5a, 6a, 41a, 42a, the fear can be reduced and a sense of security can be given to the user. . It is also possible to give the child a sense of security when the parent cuts the child's nails.
