Description

Grafting forceps{tongs for grafting}

The present invention relates to grafting tongs, and more particularly, to grafting tongs configured to be automatically separated from the grafting portion that has been grafted.

In general, farmers do grafting or grafting work to promote flowering or fruiting and increase resistance to pests and diseases. In particular, this method is widely used when cultivating gourd fruits such as watermelon, cucumber, melon, and melon or eggplant fruits such as tomatoes, peppers, and eggplants.

Such cultivars are grafted when the seedlings are young. Large trees, that is, seedlings used toward the roots, are cultivar with strong ferality, and seedlings used toward stems, that is, seedlings, are cultivar with excellent fruit.

That is, after removing the growth point of the stock, the bottom of the cotyledons is cut with a diagonal line, and then the reception desk cut with a diagonal line is placed on the cut part of the stock, and then fixed with grafting forceps for three to four days until survival.

At this time, the grafting tongs used are generally in a shape similar to a clothespin, and the tongs and the handle are formed symmetrically to each other, and a spring providing elastic force is provided between the handles.

Therefore, when the handles are gripped in a direction closer to each other, as the spring is compressed, the tongs are spread apart from each other, and the operator can position the tongs on the grafting part.

In such a state, when the operator releases his or her hand from the handle, the spring is restored to its original state, the handle is restored to its original position, and the tongs are fixed in close contact with the grafting part.

However, the grafting tongs configured as described above have a cumbersome problem in that the operator must separate the handle by gripping the handle again after the operation is completed. In particular, if a large area is manually performed, there is a problem that not only increase farming costs but also manpower difficulties may occur.

In addition, since the spring providing the elastic force is generally formed of a metal material and must be installed on the handle through a separate operation, there is a problem that not only the weight is increased but also the manufacturing cost is increased.
