[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pressing lever for bringing the blade tips of upper and lower blades into pressure contact with each other in nail clipper.

[0002]

2. Description of the Related Art Conventionally, this kind of pressing operation is
For example, there is one disclosed in Japanese Utility Model Laid-Open No. 2-43906.
This pressing lever consists of a metal lever body attached to the upper and lower blades and a decorative plate attached to the lever body.The metal lever body has a spindle inserted into the upper and lower blades. With respect to the upper blade body, a support portion rotatably supported by a support pin, a force point portion for pressing the upper blade body protruding near the support portion, and an operation plate extending from the support portion and the force point portion And a section are provided. The decorative plate is attached on the operation plate portion.

[0003] In the pressing operation lever, with notched hole in the support portion of the metallic-made lever body is formed, the action point portion in the vicinity of the support portion is protruded, the support shaft is inserted into the notched hole The support pin is rotatably supported on the support shaft by the support pin. With such a pressing operation and this supporting structure, it is necessary to integrally form the notch hole and the force point portion in the supporting portion of the metal lever body, so that the width and thickness of the supporting portion are inevitably increased, and There was a problem that molding of the lever body becomes difficult.

[0004]

As described above, the conventional problem lies in the difficulty of molding the metal lever body, and the present invention aims at dividing the metal lever body to facilitate its molding. There is.

[0005]

In view of this object, in the pressing lever 1 of the nail clipper according to the present invention, as shown in the drawings of the embodiments described later, a metal member attached to the blade bodies 11 and 12 is used. As the lever body 2, a plurality of lever plates 2a separated from each other are used. The lever plates 2a are held by the cover 3 and arranged side by side. A notch hole 10 is formed between the support portions 8 formed on each lever plate 2a. The support hole 8a formed in the support portion 8 is
It is opened to the notch hole 10 of.

[0006]

In this way, since the lever plates 2a separated from each other are held in parallel by being held by the cover 3, the notch holes 10 can be formed between the supporting portions 8 of the lever plates 2a. It is not necessary to directly form the portion corresponding to the hole 10 on each lever plate 2a.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. As shown in FIG. 1, the pressing lever 1 comprises a lever body 2 made of metal and a cover 3 made of plastic.
A projecting portion 4 is formed in the center of the base end portion of the cover 3, and arm portions 5 are projectingly provided on both sides of the projecting portion 4 with a gap 6 therebetween. As shown in FIGS. 3 and 4, a pair of storage holes 7 extending in parallel from the base end portion to the tip end portion are formed in the cover 3, and both storage holes 7 are formed in both gaps 6 at the base end portion of the cover 3. It is open.

The lever body 2 is separated into a pair of lever plates 2a having a constant thickness. A support portion 8 having a support hole 8a is formed at the base end portion of both lever plates 2a, and a force point portion 9 is provided in the vicinity of the support portion 8 so as to project. As shown in FIGS. 2 to 4, the both lever plates 2a are inserted into the both accommodation holes 7 of the cover 3, and the support portions 8 and the force application portions 9 of the both lever plates 2a are connected to the protrusion 4 of the cover 3 and both arm portions 5. It is exposed in the gap 6 between the two. Both arms 5 are overlapped with the outside of the support 8 to cover the support hole 8a. Protrusion 4 of cover 3 and both lever plates 2
A cutout hole 10 is formed between the support portion 8 and the support portion 8 a, and the support holes 8 a of both support portions 8 face the cutout hole 10.

As shown in FIGS. 5 and 6, the upper and lower blade bodies 11, 1
2 is fixed at the rear end thereof and has elasticity in a direction of approaching and separating from each other. A support shaft 13 is rotatably inserted into the upper and lower blade bodies 11 and 12 near the blade edges 11a and 12a at the front ends thereof, and the lower end portion of the support shaft 13 is locked to the lower blade body 12 and the support shaft 13 is supported. Has an upper end protruding above the upper blade 11. The upper end of the support shaft 13 on the upper blade body 11 is inserted into the notch hole 10 of the pressing lever 1, and the support pin 14 inserted into the support holes 8a of both support parts 8 is inserted and attached to the support shaft 13. The pressing lever 1 is rotatably supported on the support shaft 13.

When using such a nail clipper,
The support shaft 13 and the pressing lever 1 are rotated to turn the pressing lever 1 upside down on the upper blade body 11, and the force points 9 of both lever plates 2a are applied to the upper blade body 11. When the pressing operation lever 1 inclined on the upper blade body 11 is pressed downward, the upper blade body 11 is pressed by the two force application points 9 to cause the upper and lower blade bodies 11, 1 to move.
The two cutting edges 11a and 12a contact each other. When the pressing operation lever 1 is released, the blade edges 11a and 12a are separated from each other by the elasticity of the upper and lower blade bodies 11 and 12.

In this embodiment, the lever body 2 made of metal is used.
Since a pair of lever plates 2a separated from each other are used as the lever plates, such a notch hole is directly formed on each lever plate 2a as compared with the case of integrally molding a lever body having a notch hole as in the prior art. Since it is not necessary to form it, each lever plate 2a can be easily formed. Further, since the lever plates 2a are held in parallel by being held by the cover 3, the notch holes 10 are formed between the support portions 8 of the lever plates 2a, and the spindle 13 is inserted into the notch holes 10. You can

[0012]

According to the pushing operation lever 1 of the present invention, a plurality of lever plates 2a separated from each other are provided as the metal lever body 2.
Therefore, each lever plate 2a can be easily formed.
