Description

[Detailed description of the invention] (Industrial application field) This invention can be used to cut fruit branches of fruit vegetables such as apples, pears, cucumbers, etc. (including when picking)
This invention relates to a cutter for fruit thinning.

(Prior Art) Various kinds of thinning scissors and cutters have been provided in the past, but all of them are attached to the fingers or held in the hand. The fruit branch was grasped and the fruit branch was cut with thinning scissors or a cutter attached to or held in the fingers of the other hand.

Furthermore, in most of these cutters for fruit thinning, the cutting blade is already exposed at the most advanced position relative to the fruit body when the cutter approaches the fruit body.

(Problem to be solved by the invention) For this reason, with the conventional method, the operator's hands are easily injured by the thorns, and both hands are occupied by gripping the fruit body and the fruit-thinning cutter, making it difficult to perform other tasks. There's a problem.

In addition, in order to improve the growth and development of fruit and vegetable bodies,
In order to limit the number of fruit bodies to an appropriate number, certain fruit bodies are selected and left while other fruit bodies are cut and removed, but even in such cases, the cutting blade of the fruit thinning cutter remains exposed. If the fruit is exposed, it is difficult to select the fruit that should be left without damaging it. In other words, especially when multiple fruit are close to each other, it may be possible to accidentally remove the necessary fruit from the neighboring fruit. There was a problem that caused it to be severed or damaged.

Furthermore, since conventional fruit thinning cutters perform the cutting operation using only the force of the fingertips, they cannot be cut unless you use a lot of force, and even if you apply a lot of force, your fingertips will hurt, so you will not be able to cut the fruit in a short period of time. There was a problem in that the fingertips became fatigued over time, making it impossible to continue cutting for a long time.

The purpose of the present invention is to provide a fruit thinning cutter that solves this problem.

(Means for Solving the Problems) The fruit thinning cutter according to the present invention has a fixed gripping rod 4 which supports a pair of movable blades 1 and a fixed blade 2 in pressure contact with each other at the distal end thereof, and has a stopper part 3.
and a movable gripping rod 5 rotatably pivoted to the fixed gripping rod 4, and the movable gripping rod 5 is normally in contact with the stopper portion 3 and is spaced apart from the fixed gripping rod 4 at a constant distance. and an elastic member 6 that elastically biases the movable gripping rod 5 so that the movable gripping rod 5 can be separated.
The movable blade 1 moves forward by rotating the movable blade 1 against the elastic member 6 to cut fruit branches between the movable blade 1 and the fixed blade 2, the cutter being fixed with respect to the forward direction of the movable blade 1 A notch 7 is provided on at least one side of the blade 2 to receive the fruit branch to be cut, and a notch 18 is provided at the center of the tip of the fixed blade 2 to receive the fruit branch 9 of the fruit body 8 to be left. It is characterized by the fact that it is equipped with

(Function) Therefore, when cutting and removing the existing fruit body 8, first, for example, cut the fruit branch 9 of the fruit body 8.
As shown in FIG. 5, it is guided to the notch 7 of the fixed blade 2 and also to the notch 18 provided to receive only one fruit body 8 to be left at the center of the tip. Then, when the fruit branch 9 is guided to the notch 7, the fixed gripping piece 4 and the movable gripping piece 5 are gripped, and these
As shown by the two-dot chain line in the figure, by rotating the movable blade 1 so as to approach it, the movable blade 1 slides forward along the fixed blade 2 and cuts the fruit branch 9.

(Effects of the invention) Since the fruit thinning cutter according to the invention has the above-described configuration and function, it has the following effects.

The work of inserting the fruit branch of the selected fruit body in advance into the notch of the fixed blade and cutting it can be done with one hand and with a single touch movement by rotating the movable gripping rod, so the work of grasping the fruit branch can be done as in the past. This eliminates situations where a person's hands are injured by thorns, or where both hands are occupied and cannot be used for other tasks.

Further, even if a plurality of fruit bodies are close to each other, the fruit branches that should be left are protected from being accidentally cut, and other fruit branches can be cut and removed very easily.

(Example) Hereinafter, an example of the present invention will be specifically described based on the drawings.

1 to 4 show an embodiment of a fruit thinning cutter according to the present invention. In these figures, Figure 1 is a perspective view, Figure 2 is a vertical side view of Figure 1, Figure 3 is a rear view of Figure 2, and Figure 4 is a rear view of Figure 2.
The figure is a partially enlarged perspective view of the fruit body received in the notch.

The fruit thinning cutter according to the present invention has a fixed gripping rod 4 made of synthetic resin, the back section of which has an approximately inverted U-shape, and which is curved so that it gradually becomes thinner toward the rear. Grip rod 4
A pair of movable blades 1 and fixed blades 2, which are slightly elongated in the axial direction, are superimposed and supported in a press-contact state at the tip.

That is, as shown in FIG. 1, the movable blade 1 is superimposed on the fixed blade 2 so that their longitudinal directions almost coincide, and the movable blade 1 has a long hole 10 along the longitudinal direction of the movable blade 1. is drilled. On the other hand, a bolt 11 is provided through the fixed blade 2, and this bolt 11
The movable blade 1 is always pressed against the fixed blade 2 by inserting the movable blade 1 into the elongated hole 10 so as to face it and lightly securing it with the nut 12 and washer 19 to the extent that vertical movement of the movable blade 1 is prevented. As the movable blade 1 moves in the direction of the arrow, the bolt 11 can slide along the elongated hole 10.

A movable gripping rod 5 is rotatably attached to the fixed gripping rod 4 by a support shaft 13, and a movable gripping rod 5 is rotatably attached to the fixed gripping rod 4 on the inner upper wall of the fixed gripping rod 4, as shown in FIG. , a plate-shaped stopper part 3 is vertically provided,
The distal end of a constantly movable gripping rod 5 can come into contact with this stopper section 3 by the elastic force of an elastic member 6. More specifically, the distal end of the movable gripping rod 5 has a uniform gap 14, and a link 15 connected to the rear end of the movable blade 1 is inserted into this gap 14, and the link 15 is connected to the movable blade 1 by a pivot 16. The link 15 is rotatably attached to the movable gripping rod 5.
