Abstract

PROBLEM TO BE SOLVED: To exactly hold a stem with a pair of clamps even after cutting if off, by providing a presser to press it gradually toward its closing direction in connection with the clamps and responding to cutting a harvest held via a pair of clamps by the cutting edges corresponding to at least one clamp. SOLUTION: In cutting the harvests off the stems and branches, where to be cut off is first nipped with the cutting edges 1a, 1b. Then, closing the cutting edge 1a toward 1b gradually cuts the stem B with them 1a, 1b. The stem b1 is then held with a pair of clamps 2a, 2b, but together with the cutting operation, the presser 3 gradually presses the top edge 2a1 at the rear end of the clamp 2a toward the direction to close it. Therefore, this results in the clamp 2 to intensify the degree of holding the stamp b1 . Even after cutting the stem b1 off, a pair of clamps 2a, 2b can continue to hold and bring it to this side exactly without dropping it off the scissors, i.e., can harvest the crops with one hand.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in scissors provided with a clamp capable of holding a stem of a harvested product at the time of harvesting flowers, fruits, fruits and vegetables.

[0002]

2. Description of the Related Art As this kind of scissors, for example, there are scissors as shown in FIG. The scissors shown in FIG. 5 are a pair of cutting blades 1a '.
And a pair of clamps 2a ', 2b'
It is provided with. These scissors are useful for cutting crops off shafts and branches. In that case, first, the place to be cut is sandwiched between the cutting blade 1a 'and the receiving blade 1b', and then the cutting blade 1a 'is closed with respect to the receiving blade 1b'. The stem can be cut slowly.
At this time, a pair of clamps 2a ', 2
The stem of the crop can be held by the pair of clamps 2a 'and 2b' even after the stem is cut. Therefore, even if the harvester does not use both hands,
The harvest can be harvested with one hand.

[0003]

However, in the case of scissors of the type described above, a pair of clamps 2a 'and 2b' are formed as the cutting blade 1a 'closes with respect to the receiving blade 1b'. Since it only clamps the stem of the crop,
Even if a 'is installed so as to generate resilience, the clamping force is weak and insufficient, and the stem cut by the cutting blade 1a' and the receiving blade 1b 'is clamped by a pair of clamps 2a' and 2b '. However, there is a drawback that it cannot be grasped with certainty, and is likely to come off. The same applies to the case where the receiving blade 1b 'in FIG. 5 is a cutting blade in the same manner as the cutting blade 1a'.
The stem cut by b ′ cannot be reliably held by the pair of clamps 2a ′ and 2b ′. That is, the conventional scissors grasp the stem of the crop with a pair of clamps 2a 'and 2b', and at the same time, perform a movement of cutting the stem with the cutting blade 1a 'and the receiving blade 1b' or the cutting blade and the cutting blade. Only. Therefore, it has a disadvantage that it is extremely insufficient in grasping the stem. An object of the present invention is to eliminate the above-mentioned drawbacks.

[0004]

In order to achieve this object, according to the present invention, a cutting blade 1a corresponding to at least one clamp 2a cuts a crop B held by a pair of clamps 2a and 2b. In this case, there is provided a pressing body 3 which engages with the clamp 2a and gradually presses it in a direction to close the clamp 2a. When cutting the crop from the shaft or branch, first, the cutting point is sandwiched between the cutting blade 1a and the cutting blade 1b or the receiving blade, and then the cutting blade 1a is closed with respect to the cutting blade 1b or the receiving blade. Then, the cutting blade 1a and the cutting blade 1b or the receiving blade gradually increase the stem B.
Can be cut. At this time, the side of the stem b ₁ a pair of clamps 2a to be separated, can be gripped by 2b, the押体3 is gradually pressed in the direction to close the clamp 2a together with the cutting operation. Therefore, the clamp 2a
The degree grab b ₁ becomes strong, stems b ₁ also crop after stems are cut can be drawn pair of clamps 2a, continue to be pinched by 2b, to reliably hand without departing from the scissors. That is, even if the person engaged in the harvesting operation does not use both hands, the harvest can be reliably harvested with one hand.

[0005] As described above, the scissors of the present invention include a pair of clamps.
Grab the stem of the crop with 2a and 2b, and almost simultaneously with this, the cutting blade 1a
Then, the stem is cut by the cutting blade 1b or the receiving blade, and the force is applied to at least one of the clamps 2a by the force of gripping the scissors, so that the stem can be more strongly gripped. That is, it is possible to grab stronger stems b ₁ side to be separated by the force of the hand gripping the shears during the cutting operation. Therefore, unlike the prior art, can be more strongly gripping the stem b ₁ side of is also disconnected after the stem has been cut.

Preferably, at least one of the pair of clamps 2a, 2b is biased in a direction to close the other clamp 2b. This way,
Since at least one of the clamps 2a exerts a force on the other clamp 2b in the closing direction, the pair of clamps 2a and 2b can more strongly hold the stem of the crop.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described in detail with reference to the drawings. 1, the cutting blade
A pair of blades composed of a cutting edge 1a and a cutting edge 1b, and a pair of clamps 2a and 2b corresponding to the two cutting edges 1a and 1b, respectively, are pivotally connected by one shaft 4. In the case shown here, the clamp 2b corresponding to the cutting edge 1b of the pair of clamps 2a, 2b has a U-shaped side surface, and the cutting edge 1a and the cutting edge
When the pair of blades 1b is closed, the leading end of the mating clamp 2a fits into the groove 5 thereof. On the lower surface of the clamp 2a corresponding to the cutting blade 1a and the upper surface of the side U-shaped clamp 2b corresponding to the cutting blade 1b, both jagged teeth 6a, 6b are formed, so that the harvested product to be gripped can be obtained. The stem is not slippery.

On the other hand, at the portion of the cutting blade 1b behind the shaft 4, that is, between the shaft 4 and the handle 7b, a pressing body 3 is provided.
Are provided so as to protrude. The pressing body 3 has a cutting blade 1a corresponding to one clamp 2a and a pair of clamps 2a and 2b.
The is to gradually pressed in the direction for closing this upper edge 2a ₁ part engage clamping 2a rear according to cut the crop B being clamped.

[0009] In separating the crops from the shafts and branches,
First, the place to be cut is sandwiched between the cutting blade 1a and the cutting blade 1b. After that, when the cutting blade 1a is closed with respect to the cutting blade 1b, as shown in FIG. Can gradually cut the stem B. At this time, the side of the stem b ₁ a pair of clamps 2a to be separated, can be gripped by 2b, as shown in FIG. 4, the押体3 clamp together with the cutting operation
The upper end edge 2a ₁ part of 2a rear gradually pressed in the direction to close. Thus, the clamp 2a becomes stronger the degree grab stem b _1, stem b ₁ also crop after stalk is cut a pair of clamps
It continues to be pinched between 2a and 2b, and can be pulled to the hand without coming off the scissors. That is, even if the person engaged in the harvesting operation does not use both hands, the harvest can be reliably harvested with one hand.

It is preferable that one of the pair of clamps 2a, 2b is biased in a direction to close the other clamp 2b. In this case, for example, as shown in detail in FIG. 2, an elongated hole 8 is formed in a pivotally connected portion of one of the clamps 2a, and the shaft 4 is fitted therein, while the rear end of the clamp 2a is An example is given in which a spring 10 is wound around a shaft 9 mounted nearby, and one end is fixed to the clamp 2a side and the other end is fixed to the handle 7a side. In this way, one clamp 2a exerts a force in the direction of closing with respect to the other clamp 2b, so that the pair of clamps 2a and 2b can more strongly clamp the stem of the crop.

Here, the case where the pair of blades is composed of the cutting blade 1a and the cutting blade 1b is exemplified, but it is needless to say that one blade, for example, the cutting blade 1b may be used as the receiving blade. . Also, here, the case where only one clamp 2a of the pair of clamps 2a and 2b is urged in the direction to close with respect to the other clamp 2b has been illustrated, but both clamps 2a and 2b are connected to the other clamp 2a. It may be biased in a direction to close the clamp.

[0012]

When the scissors according to claim 1 are used, at least one of the cutting blades 1a is closed with respect to the other cutting blade 1b or the receiving blade, so that the clamp 2a is used for the cropping. Since the degree of grasping the stem is increased, there is an effect that the stem of the crop can be reliably clamped by the pair of clamps 2a and 2b even after the stem is cut.

When the scissors according to the second aspect are used, at least one of the clamps 2a exerts a force on the other clamp 2b in the closing direction, so that a pair of clamps 2a is used.
Since the stem of the crop can be more strongly clamped by a and 2b, even after the stem is cut, the stem of the crop is clamped more strongly and more securely by the pair of clamps 2a and 2b. There is an effect that can be.
