Description

TECHNICAL FIELD The present invention relates to improvement of scissors such as barber scissors and scissors for office use.

(Prior Art) Scissors cut an object by rubbing two opposing blades together. The two opposing blades are joined by screws at the branch,
If the two blades are screwed together relatively tightly, the blades will be tightly fitted together. On the contrary, if the two blade screws are relatively loosely coupled, the blades will be loosely fitted.

In the conventional product, the adjustment of the blade fitting was performed by a pivot nut connecting two scissors. However, the pivot is an important part of determining the usage state of the scissors, and if it can be loosened or tightened frequently, the nut is loosely screwed that much, so the nut will soon loosen when the scissors are used. It is necessary to retighten the nut frequently. In other words, since the pivot including the nut is the center of rotation of the scissors, it is inevitable that the nut will loosen when the scissors are used. Therefore, it is desirable that the pivot is rigidly connected from the beginning so that the nut does not loosen, and that the user can adjust the adjustment of the blades to be adjusted by a portion other than the pivot when the user chooses his / her preference.

Also, even if the nut of the pivot is loosened a little, it is desirable to adjust the adjustment of the blades with the nut, not the nut.

(Problems to be Solved by the Invention) The present invention eliminates the drawbacks of the conventional products and does not adjust the grinding condition of the blade at the pivot portion but at a portion that is not affected by the rotation of the scissors. An object of the present invention is to provide scissors capable of easily adjusting the blade's fitting, without the need to repeatedly tighten the scissors body.

(Means for Solving Problems) According to the configuration of the present invention, two scissors 3, 3 in which the blade 2 is connected to the front of the handle 1 are rotatably coupled by the pivot 4, and one scissors 3 A plate-like elastic contact point member 6 is attached along the length direction of the handle 1 on the surface of the rear side of the pivot 4, and the rear end of the contact point member 6 is It is fixed to one of the scissors 3 to be in a cantilever state, and a tip 5 of the touch point member 6 is provided with a touch point 5 extending in a direction perpendicular thereto, and the touch point 5 is provided on the one scissor body 3. The scissors 3 are in contact with the inner surface of the other scissors 3 through a hole 7 formed therein, and one scissors 3 is inserted through a through hole 8 provided midway between the front end and the rear end of the contact point member 6.
The shaft screw 9 rises from the surface of the shaft screw 9, and the floating contact point member 6 can be tightened by the nut 10 attached to the shaft screw 9.

(Example) Next, the structure of the present invention will be described with reference to the drawings showing an example.

Reference numerals 3 and 3 are scissors constituting scissors, a blade 2 is connected to the front of a handle 1, and is pivotally attached by a pivot 4. The contact point member 6 is a metal piece, and the tip of the contact point member 6 floats up, bends in an L shape, passes through a hole 7 formed in the scissors body, and protrudes to the inner surface of the scissors body 3, and the tip thereof touches the contact point 5. Becomes A through hole 8 is formed in the middle of the metal piece, and a shaft screw 9 fixed to the scissors passes through the through hole 8 and sticks out to the outer surface of the metal piece. A nut 10 is screwed onto the shaft screw 9. By tightening or loosening the nut 10, the melting point 5
The amount of protrusion of the inner surface of the can be adjusted. Since the metal piece has a leaf spring structure and is highly elastic, the contact point 5 is supported by this metal piece and can be elastically displaced by a small force. The contact point 5 abuts against the inner surface of the other scissors 3 and pushes it, so that a pressure contact force acts on the intersection of the blade edges 11, 11 of the blade portion 2 in front of the pivot 4 as a reaction thereof.

(Operation / Effect) When the user of the scissors of the present invention adjusts the strength of the blade fitting to the user's preference, the looseness of the contact point member 6 can be adjusted by loosening or tightening the nut 10. The movement of the contact point member 6 can change the force with which the contact point 5 presses the inner surface of the other scissors body, so that the strength of the grinding of the blades can be freely adjusted by this work.

The present invention has the above-described structure, in which the contact point member 6 is fixed to the scissors independently of the pivot 4, and the adjustment of the blade fitting is not performed by the pivot 4 but by the nut 10 separate from the pivot 4. It is configured to do. Therefore, even if the pivot 4 is formed so as not to easily loosen or is fixedly formed so as not to loosen at all, it can be easily adjusted by the separate nut 10. . Conventionally, scissors are adjusted by a nut of a pivot, so that the nut is attached loosely to some extent so that it can be easily rotated. Moreover, since this nut is located at the center of the rotation of the scissors, it quickly loosens when the scissors are rotated. In the present invention, since the pivot can be formed so as to be hardly loosened, the pivot is hard to loosen even when the scissors are used for a long period of time. Further, in the present invention, since the nut 10 for adjusting the grinding of the blades is located away from the center of rotation of the scissors, the nut 10 is not affected by the rotation of the scissors and the scissors are used for a long time. However, the nut 10 does not loosen, and once adjusted, the adjustment becomes unnecessary for a long period of time.

Further, even if the pivot shaft 4 is loosened a little, the contact point member 6 is highly elastic, so that the looseness of the pivot shaft can be absorbed by the contact point member 6 and the rattling of the scissors can be suppressed.
