Next, a nail clipper according to a second embodiment of the present invention will be described with reference to FIGS.
A pair of blades 37, 38 are supported by a rotation center portion 39 so as to be openable and closable and intersect in an X shape. Both blades 37, 38 have blade edges 41 a, 42 a on the tip side of the rotation center portion 39. The bodies 41, 42 are provided as the blade body 40, and both the blades 37, 38 are provided with both handles 44, 45 as the operation part 43 on the proximal end side with respect to the rotation center part 39. A blade spring 46 as a regulating member is supported on the handle 44 of one blade 37 so as to be movable in a plurality of stages in the longitudinal direction of the handle 44 and attached by a set screw 47, and a tip end portion 46a of the plate spring 46 is attached. 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.
