The blades 1 and 2 are formed by joining two vertically symmetrical metal plates having a blade tip at the tip, and the base portions of the plates are overlapped, and the overlapped portion is welded. Or it is fixed with screws or the like.
In the present embodiment, the bases 5 of the two blades 1 and 2 are in close contact with each other, but the gap between the two blades gradually increases toward the blade edge, and a gap 6 extends between the blade edges at the tip. Is formed.
The tip of the blade edge is configured such that the blade edge 1a of the upper blade 1 is bent obliquely downward and the blade edge 2a of the lower blade 2 is bent obliquely upward, and both are pressed by lever operation.

The upper blade 1 and the lower blade 2 are overlapped so as to repel each other with the close contact point as a base point, and the repulsive upper blade 1 and the lower blade 2 are inserted by the pin 7 and the base of the front lever 8 inserted through the tip. Tethered.
The two plate-like bodies function as biasing means 4 (springs) that repel each other by being overlapped, and after cutting the claws by pressing the upper blade 1 and the lower blade 2 by lever operation, A force to return to the original force is applied by the repulsive force of the spring.

The operating portion 3 includes a front lever 8 attached to the front of the blade and a rear lever 9 attached to the rear of the blade.
The lower end of the front lever 8 is attached to the upper side of the upper edge of the upper blade 1 and is bent upward from the attachment site to the rear of the blade.
The lower end of the rear lever 9 is attached in close contact with the lower surface of the lower blade 2, and is bent forward and extended upward from the attachment site.

The lower end of the front lever 8 is connected to the head of the pin 7 through a horizontally passing shaft and presses the upper side of the upper blade 1 against the repulsive force of the upper blade 1.
The pin 7 is inserted in a vertical direction through a through hole 10 at the tip of the upper blade 1 and the lower blade 2, and the pin 7 penetrates the upper blade 1 and the lower blade 2 up and down.
On the lower surface of the lower blade 2, a stopper 11 having a pin 7 widened is exposed (see FIG. 5).
An upper end of the pin 7 protrudes above the upper blade 1 and a front lever 8 is connected to the head of the pin 7 via a horizontal shaft.
A contact portion 12 that contacts the upper surface of the upper blade is set about 1 cm behind the connecting portion between the front lever 8 and the pin 7, and this contact portion 12 presses the upper blade 1 against the lower blade 2 when operating the lever. Function as. That is, when the front lever 8 is tilted rearward, the contact portion 12 functions so that the contact portion 12 is pushed down with the connection portion (horizontal axis) to the pin 7 as a fulcrum and the upper blade 1 is pushed down.

The front and rear levers 8 and 9 are composed of thin rod-like members having a width of about 1 cm, the front lever 8 extends upward about 12 cm from the blade, the rear lever 9 extends upward about 10 cm, and the upper ends of the front and rear levers 8 and 9 The gripping portions 8a and 9a are arranged in the horizontal direction so as to intersect the T-shape.
