Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutting tool for cutting chrysanthemums, carnations and other flower stems for the purpose of shipping.

[0002]

Pruning shears are most commonly used to cut flower stems. However, in flowers such as chrysanthemums and carnations, the stem is cut near the root. In this case, since it is inconvenient to use the pruning scissors, a cutting tool as shown in FIG. 11 is used. In this cutting tool, a small sickle-shaped blade B is attached to the tip of a long supporting rod A, and an operator pulls the vicinity of the root of the flower stem in a standing posture toward you. Can be cut.

[0003]

In the conventional flower cutting tool shown in FIG. 11, an operator can cut the flower stem from a position near the root in a standing posture, but a sickle-shaped blade. When the body was pulled strongly toward the hand, there was a drawback that the stem was pulled out from the root without being cut.
As described above, if the stem is pulled out without being cut, the strain itself will die, and there will be a drawback that the growth of the strain thereafter will be hindered. There is also a drawback that when a sickle-shaped blade having a certain size is pulled, adjacent stems other than the stem to be cut are likely to be cut. This is especially likely to be the case when densely planted. In view of the above-mentioned drawbacks of the prior art, the worker can perform the work in a standing posture, the stock is not pulled out, and the stems other than the one to be cut are not mistaken. The purpose of the present invention is to obtain a flower stem cutting tool that will not be cut by cutting.

[0004]

In order to solve the above-mentioned problems, according to the present invention, a blade 2 having a cutting blade 3 directed toward the tip is attached to the tip of a support rod 1, and the tip of the blade 2 is attached to a guard rod. Surround with 4.
Then, by opening a part of the guard rod 4 toward the base, it is possible to guide the stem of the flowering plant from the base of the blade 2 to the tip of the cutting blade 3, and hold the support rod 1 to move the blade 2 Only the stalks of the flora introduced to the tip of the cutting edge 3 are pushed by pushing the tip. This allows the work to proceed without exerting a force in the direction of pulling out the plant on the stem of the flower.

The blade 2 mounted on the tip of the support rod 1 is fixedly attached to a short-sized blade holder 5, and this blade holder 5
It is convenient to handle if the front end of the long-length supporting rod 1 is detachable. Further, when the cutting blade 3 formed at the tip of the blade body 2 is inclined with respect to the pushing direction of the blade body 2, it is possible to effectively cut the stem that is the object to be cut. Further, one end of the guard rod 4 surrounding the tip of the blade 2 is pivotally attached to the base of the blade 2 so that the guard rod 4 surrounding the tip of the cutting blade 3 can be removed from the tip of the cutting blade. At the same time, it is preferable to provide a locking means for locking the guard rod 4 at the position rotated to the tip of the blade. This is convenient because the guard rod 4 does not get in the way when the blade body is cared for such as polishing the cutting blade.

In addition, a guard rod 4 surrounding the tip of the blade 2 is attached to a guard holder 6 which is a separate body, and this is attached to the blade 2.
Alternatively, if the blade holder 5 or a part of the support rod 1 can be detachably attached, it is convenient not only for polishing and other maintenance of the blade, but also for removing the guard holder 6. Can be used as a general blade.

FIG. 1 is a front view of only a tip portion of a stem cutting tool according to the present invention, FIG. 2 is a rear view thereof, and FIG. 3 is a central longitudinal sectional view.

In this stem cutting tool, a detachable blade holder 5 is attached to the tip of a long support rod 1,
A blade body 2 with a cutting blade 3 facing forward is attached to the tip of the support rod 1. That is, as understood from FIG. 3, a notch 8 is formed from the upper end surface of the blade holder 5 formed in a cylindrical shape, and the base of the flat blade 2 is inserted into the notch 8 and the set screw 7 is used. Fix it. A male screw 9 is formed on the base end portion of the blade holder 5, and the tip of the support rod 1 is a female screw cylinder so that it can be freely attached to and detached from the tip of the support rod 1. Of course, in the illustrated embodiment, the blade holder is attached to and detached from the tip of the support rod 1, but the blade 2 may be directly attached to the tip of the long-length support rod 1.

The blade 2 has a guard rod 4 surrounding the tip of the blade.
Put on. The guard rod 4 of the embodiment shown in FIGS. 1 and 2.
Surrounds the tip of the blade by bending the tip of the wire whose one end is fixed to the base end of the blade to detour the tip of the blade. The tip of the detoured wire rod is the blade 2
The stem of the flower can be easily passed by opening it toward the base of. That is, a gap having a dimension X that allows the flower shaft to pass is formed between the bypassed wire rod as the support rod 1 and the side edge of the blade body 2. The base end of the wire rod as the guard rod 4 is fixed to the blade body 2 by an adhesive or brazing, but an intermediate fixing portion 10 is provided at the side edge of the blade body so that the guard rod 4 can be mounted more stably. The intermediate fixing portion 10 is also supported. It is preferable that the support rod 1 be firmly held by such two-point support.

The working process using the above-described stem cutting tool will be described with reference to FIG. For example, when attempting to cut the stem b of the flower stems a, b, and c that are planted at relatively narrow intervals, as shown in FIG. 4 (a), the tip portion of the stem cutting tool from the front side. That is, the tip portion of the guard rod 4 is pushed between the stems b and c. At this time, even if the intervals of planting the flowers are narrow, the stems b and c are pushed away to both sides by the guard rod 4 as shown by the arrows, and as shown in FIG. The tip of 2 is pushed out to the other side of the flower.

Next, as shown in FIG. 4B, the entire stem cutting tool is moved to the front while guiding the stem b to be cut to the open portion of the guard rod 4. Then, as shown in (c) of FIG. 4, the flower stem b is taken inside the guard rod 4.
In this state, when the entire stem cutting tool is pushed forward as indicated by the arrow, the stem b of the target flower is b as shown in FIG. 4 (d).
Only disconnected. At this time, the stems a and c are forcibly pushed outward by the guard rod 4, so that the stems other than the intended one are not accidentally cut even if they are planted at narrow intervals. .

The above-mentioned cutting work of the stem shown in FIG.
As shown in, the operator holds the base end portion of the support rod 1 by hand. Therefore, the operation of cutting the stalk shown in (c) to (d) of FIG. 4 is performed by moving the cutting blade that presses downward from diagonally above. This means that even if the cutting edge 3 has poor sharpness, the cutting force acts as a force to press the stock toward the ground, and the force does not act in the direction to pull out the stock. Therefore, there is no possibility that the flower stock will be pulled out carelessly.

The guard rod 4 formed by bending (curving) a wire rod may be bent on the same plane as the blade as shown in FIG. As shown in (b), the tip of the wire forming the open end can be bent in a direction intersecting the plane of the blade.
