Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention [Industrial Application Field] The present invention relates to a method for supporting a lever operated by pressing on an upper blade body with respect to a spindle inserted through both upper and lower blade bodies in a nail clipper.

[Problems to be Solved by the Related Art and the Invention] In a conventional general nail clipper, both upper and lower blades are fixed at their rear ends, and their blade edges have elasticity in a direction to approach and separate from each other, The support shaft is rotatably inserted into the upper and lower blades, the lower end of the support shaft is locked at the lower blade body, and the upper end of the support shaft projects above the upper blade body, and the upper blade A pressing lever is rotatably supported by a pin on the upper end of the support shaft on the body.

In such a nail clipper, when assembling the pressing lever to the support shaft, first insert the support shaft into the upper and lower blades, and then press the upper and lower blades in directions approaching each other,
The upper end of the support shaft is projected above the upper blade body, and in this state, the insertion hole of the support shaft and the insertion hole are made to correspond to each other by pressing operation, and the pins are inserted into both the insertion holes.

However, since the support shaft rotates freely with respect to the upper and lower blades, not only is it difficult to match the insertion hole with the insertion hole of the support shaft by pressing, but also during the insertion of the pin, the matching state is maintained. Had to hold. Moreover, at this time, the pressing of the upper and lower blades must be simultaneously held.
Therefore, the assembling work was very troublesome.

In view of the above, various types have been devised in which the support shaft itself is provided with rotation preventing means for the upper and lower blades and the pressing lever.

The present invention does not provide a rotation preventing means for the upper and lower blades and the pressing lever on the spindle itself, but performs the pressing operation with the supporting shaft freely rotating with respect to the upper and lower blades and the pressing lever. It is intended to be easy.

Configuration of the Invention [Means for Solving the Problems] In order to achieve this object, as shown in the drawings of the embodiments described below, the present invention is provided with elasticity in the direction in which the cutting edges 1a and 2a approach and separate from each other. The support shaft 3 is inserted into the upper and lower blades 1 and 2 so that the head 4 at the lower end of the support shaft 3 is locked to the lower blade 2, and the upper end of the support shaft 3 projects above the upper blade 1. In this state, the fixing portion 10 is attached to the rotation preventing portion 9 formed on the head 4 of the support shaft 3.
To prevent rotation of the support shaft 3 with respect to the fixed portion 10, and press the lever 6 into the insertion hole 5 at the upper end of the support shaft 3.
The insertion holes 7 are aligned with each other, the pins 8 are inserted into both the insertion holes 5, 7, and the pressing lever 6 is rotatably supported on the upper blade 1.

[Operation] According to this mounting method, the support shaft 3 inserted into the upper and lower blades 1 and 2 is engaged with the fixed portion 10 by the rotation preventing portion 9 and its rotation is prevented.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

As shown in FIGS. 1 to 3, the upper and lower blades 1 and 2 are fixed at their rear ends, and the blade edges 1a and 2a formed at their front ends have elasticity in a direction to approach and separate from each other. In the vicinity of the two cutting edges 1a and 2a, the support shaft 3 is rotatably inserted into the upper and lower cutting edges 1 and 2, and the head 4 at the lower end of the support shaft 3 is locked to the lower surface of the lower blade body 2. The upper end of the support shaft 3 projects above the upper blade 1. An insertion hole 5 is provided at the upper end of the support shaft 3.
Is pierced. An insertion hole 7 is formed at the front end of the pressing lever 6, and a pin 8 is inserted into the insertion hole 7 and the insertion hole 5 of the support shaft 3, and the pressing lever 6 is turned on the upper blade 1. It is movably supported.

The procedure for supporting the pressing lever 6 on the support shaft 3 in such a nail clipper will be described in detail.

First, as shown in FIG. 4, with the upper and lower blades 1 and 2 pressed toward each other, the support shaft 3 is moved to the upper and lower blades 1 and 2.
And a fixed shaft 10 having a cross-shaped cross section is fitted into a cross-shaped detent hole 9 formed in the head 4 of the support shaft 3.
Therefore, by the engagement between the fixed shaft 10 and the detent hole 9,
The support shaft 3 cannot rotate with respect to the fixed shaft 10.

In this state, the insertion hole 5 at the upper end of the support shaft 3 protruding above the upper blade body 1 and the insertion hole 7 at the front end of the pressing lever 6 are aligned.
As shown in FIGS. 5 and 6, the pins 8 are fitted to each other, and the pins 8 are inserted into the insertion holes 5 and 7.

In particular, in this embodiment, the support shaft 3 inserted through the upper and lower blades 1 and 2 is engaged with the fixed shaft 10 by the rotation preventing hole 9 and its rotation is prevented. 5 and the insertion hole 7 of the lever 6 can be easily aligned.
During the insertion of the lever 6 into the insertion holes 5 and 7, it is easy to maintain the matching state, and the assembling work of the pressing lever 6 becomes very easy.

The detent means formed on the head 4 of the spindle 3
Notches formed in the outer periphery of the head 4 may be used in addition to the detent holes 9 in the above embodiment.

According to the present invention, the support shaft 3 is fixed to the upper and lower blades by the engagement between the rotation preventing portion 9 formed on the head portion 4 of the support shaft 3 and the fixing portion 10.
Since it does not rotate with respect to 1, 2 and the pressing lever 6, the assembling work of the pressing lever 6 with respect to the support shaft 3 becomes very easy.
