Description

Description: TECHNICAL FIELD The present invention relates to a support structure for a pressing operation in a nail clipper.

[Prior Art] Conventionally, in a nail clipper as disclosed in, for example, Japanese Utility Model Laid-Open No. 62-148202, the front end portions of the upper blade body and the lower blade body, which have elasticity in a direction in which they approach and separate from each other, are With the elastic blades approaching each other against elasticity, the support pins are rotatably inserted from the lower blade body side to the upper blade body side through the insertion holes near the front ends of the upper and lower blade bodies, and in this state After pressing the upper end of the support pin to insert it into this notch, press the insertion hole at the upper end of the support pin to match the insertion hole of this front end and insert the spindle into them. As a result, the pressing lever is rotatably supported with respect to the support pin.

[Problems to be Solved by the Invention] In the pressing operation lever support structure as described above, until the insertion of the support shaft into the pressing operation lever is completed,
The front ends of the upper and lower blades are made to approach each other against their elasticity, and the support pin and the pressing operation are performed to hold the state where the engaging holes are aligned with each other, while inserting the support shaft into the insertion holes. There must be. Therefore, there is a difficulty in assembling that many such operations must be performed at once.

It is an object of the present invention to provide this support structure by performing a pressing operation in a nail clipper that makes it easy to assemble the pressing operation lever with respect to the support pin without performing many operations at once.

[Means for Solving the Problems] In order to solve the above problems, the present invention inserts a support shaft of a support member supported by upper and lower blades into a locking groove formed at a front end of a pressing operation. By pressing the opening portion of the locking groove and supporting the locking groove on the support shaft, the pressing operation lever is rotatably attached to the support member, and the pressing operation is performed in a nail clipper. did.

[Operation] According to the pressing operation and the support structure, the first step of inserting the support shaft of the supporting member supported by the upper and lower blades into the locking groove by the pressing operation, and the opening of the locking groove The pressing lever can be attached to the support member by dividing the procedure into the second step of pressing the portion to support the supporting groove on the support shaft.

[Embodiment] The first to fifth embodiments of the present invention will be described below.
Description will be given with reference to the drawings.

As shown in FIGS. 1 and 5, the upper blade 1 and the lower blade 2 are fixed to each other at their rear end portions and have elasticity in a direction in which they approach and separate from each other. Cutting edges 1a, 2a are formed which come into contact with each other when they approach each other. In addition, through holes 3 and 4 are provided in the vicinity of the front ends of the upper and lower blade bodies 1 and 2, respectively, and a support pin 5 as a supporting member is inserted into these insertion holes 3 and 4 from the lower blade body 2 side to the upper blade. The lower end of the support pin 5 is locked to the lower surface of the lower blade body 2 by being rotatably inserted to the body 1 side. An insertion hole 6 is formed at the upper end of the support pin 5.

On the other hand, as can be seen from FIG. 1, a notch 9 is formed in the front end of the pressing lever 8 and a locking groove 11 is formed in the support portions 10 on both the left and right sides of the notch 9. There is.

Next, the procedure for assembling the pressing lever 8 to the support pin 5 will be described in detail.

First, as shown in FIGS. 2 and 3, the insertion holes 3, 2 for the upper and lower blades 1, 2,
After inserting the support pin 5 into the 4, the front end portions of the upper and lower blade bodies 1 and 2 are made to approach each other against their elasticity, and the insertion hole 6 of the support pin 5 is projected above the upper blade body 1 and The support shaft 7 is inserted into the insertion hole 6 so that the support pin 5 does not fall out from the insertion holes 3 and 4 of the upper and lower blades 1 and 2.

Next, as shown in FIG. 4, the upper end of the support pin 5 is inserted into the notch 9 of the pressing lever 8 and both ends of the support shaft 7 inserted into the supporting pin 5 are pressed. Gutter 11
Then, the pressing lever 8 is placed on the upper blade 1.

Further, as shown in FIG. 5, the opening of the locking groove 11 is pressed to support the locking groove 11 on the support shaft 7, and the pushing lever 8 is vertically moved around the support shaft 5 with respect to the support shaft 7. Rotatably attached to.

In the nail clipper configured as described above, after inserting the support pin 5 into the upper and lower blades 1 and 2, the support shaft 7 is inserted into the support pin 5, and both ends of the support shaft 7 are pressed. The pressing operation lever 8 can be assembled by dividing the procedure into a first step of inserting the locking groove 11 and a second step of pressing the opening of the locking groove 11. Therefore, unlike the conventional nail clippers, the nail clipper of the present embodiment does not require many assembling operations at once, and is a nail clipper that is very easy to assemble.

Next, a second embodiment shown in FIG. 6 will be described. The difference between the second embodiment and the first embodiment is the support pin 5 and the upper and lower blades.
There are 1 and 2 configurations. That is, the support shaft 5 is integrally formed with the support shaft 7 in advance at the upper end portion thereof, while the upper blade 1 and the lower blade 2 are respectively replaced with the insertion holes 3 and 4 in the first embodiment, and the insertion groove 12 is formed. , 13 are provided. These insertion grooves 12, 13 correspond to the shape of the support pin 5 shown in FIG. 6 when viewed from directly above,
The support pin 5 has a shape that can be inserted therethrough.

Therefore, when assembling the support pin 5,
After being inserted into the insertion grooves 12 and 13 of the blades 1 and 2, the front end portions of the upper and lower blade bodies 1 and 2 are made to approach each other against their elasticity, and the support shaft 7 of the support pin 5 is projected above the upper blade body 1. At the same time, the support pin 5 is rotated 90 degrees about its axis, and the support shaft 7 is rotated.
The projecting direction of is orthogonal to the insertion groove 12 of the upper blade 1. This state corresponds to the state shown in FIG. 3 in the first embodiment. Hereinafter, the pressing lever 8 can be attached to the support shaft 7 of the support pin 5 in the same manner as in the first embodiment.

In the second embodiment, since the support pin 5 and the support shaft 7 in the first embodiment are integrated, the number of parts can be reduced and after the support pin 5 is inserted into the upper and lower blades 1 and 2. Also, the support pin 5 can be easily prevented from falling off.

[Effect of the Invention] According to the pressing operation of the present invention, the supporting structure has the first step of pressing the support shaft of the supporting member supported by the upper and lower blades to insert the supporting shaft into the locking groove, and the opening of the locking groove. Since the pressing lever can be attached to the support member by dividing the procedure into the second step of pressing the portion to support the locking groove on the support shaft, an excellent effect that the pressing lever can be easily assembled to the support member. Play.
