Description

[Detailed Description of the Invention] An object of the present invention is to provide flower cutting scissors that can open the cutting edge widely even with a small operation of the handle lever, and can insert the object to be cut deep into the body and cut it efficiently. be.

Conventional flower cutting scissors, as shown in FIG. 1, do not open the cutting edge wide unless the handle lever is moved up and down significantly, and the shearing force is concentrated only on the cutting edge, making it difficult to cut efficiently.

Furthermore, in order to widen the cutting edge, it is necessary to make the handle lever long, which increases the overall size, makes operation difficult, and increases cost.

The present invention aims to eliminate the problem of slanting, and an example of the implementation of the present invention will be described below based on the drawings.

FIG. 2 is an exploded view of the product of the present invention.

In the drawings, reference numeral 1 denotes an upper cutting blade body, in which a slit 2 is bored in the center of the neck.

In this case, the hole 2 is formed so as to be inclined upward toward the tip of the blade, and in the illustrated example, the inclination angle θ is 10°.

Reference numeral 1' denotes a lower cutting blade body, in which a sling 1-2' is bored inside the center of the neck as described above.

However, in this case, the slit 2' is formed with an inclination that descends toward the tip of the blade, and the inclination angle θ' is -100.

3.3' is the slit 2°2' of the upper and lower cutting blades 1 and 1'.
A pair of left and right floating plates are made to come into contact with the side surfaces of the plate, and holes 4° and 4' for inserting pins, which will be described later, are bored at the front and rear ends.

5 is a fixing pin, 6 is an oak), 7.7' is an L-shaped handle lever, and 8, 8' and 10.1 are
0' is a pin and nut for fixing each cutting blade body and the handle lever, and 9 and 11 are pins and nuts for fixing the floating plate and the handle lever.

Figures 3 and 4 show the assembled state, with floating plates 3,
3', insert the pin 5 from one side, and fix it using the nuts 6 on the opposite sides.

On the other hand, the handle levers 7 and 7' are rotatably fixed at the L-shaped corners using the cutting blades 1 and 1' and the pins 8° and 8' so that they are opposed to each other. , the lower one tip is rotatably connected to the floating plates 3 and 3' using a pin 9.

The present invention is constructed as described above, and the handle levers γ, 7'
If you hold it in your hand and open it up and down, the floating plates 3, 3'
is pulled rearward, and the blade tips of the upper and lower cutting blade bodies 1, 1' are opened.

At this time, the pin 5 is pulled rearward along the inclination angles θ and θ' of the slit 2°2', so even if the handle lever is slightly opened, the cutting edge is wide open, making it possible to insert the object 11 deep into the cutting. It is something that can be done.

(See Fig. 4) Therefore, according to the present invention, the cutting edge can be opened wide by simply opening the handle lever a little, and the object to be cut can be inserted deep into the cutter to cut it. The object to be cut can be gripped reliably and efficiently cut with a large shearing force.

In addition, the inclination angle θ (θ
') may be any angle within the range of 3°≦θ≦80°, but is usually designed to be an angle of 5° to 45°.

In this case, when θ is 3°, the above effects cannot be sufficiently obtained.

On the other hand, when θ>80°, although the cutting edge is wide open, a relatively large force is required for cutting, resulting in a decrease in cutting performance.

Claims (1)

[Claims] 1. A slit with an inclination angle θ that rises toward the blade tip is formed in the upper cutting blade body, and a slit with a similar inclination angle θ that points downward toward the blade tip is bored in the lower cutting blade body. is 3°≦θ≦8
In addition to making the 0° angle, a pair of left and right floating plates with pin insertion holes drilled at the front and rear end positions from both sides of the paired slits are brought into contact with each other, and the holes at the front end positions of the floating plates and the above-mentioned A pin is installed to pass through the slit in the upper and lower cutting blade bodies, while the gripping levers are formed into a pair of L-shaped pieces that face each other vertically, and the L-shaped corners of both handle levers and the back of each cutting blade body are attached. The end edge is rotatably pinned, and the tip of the other handle lever is held between the rear end of the floating plate, and the hole drilled in the tip of the handle lever and the hole at the rear end of the floating plate are connected to each other. These flower cutting scissors are characterized by being constructed by aligning the opposite sides and pivoting them with a pin so that they can rotate freely.
