Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a graft graft used for fixing a rootstock and a scion grafted to the rootstock.

[0002]

[Prior Art]

 As shown in Japanese Utility Model Laid-Open No. 2-138529, a conventional clip for grafting is composed of a cylindrical elastic body formed with a slit extending in the axial direction over the entire length. At the time of grafting, the size of the slit is expanded so that the connection part of the rootstock and the scion is inserted into the sleeve through the slit, and then the expansion of the slit is released to allow the sleeve to grip the rootstock and the scion. Spreading and unfolding the clip are done manually.

[0003]

[Problems to be solved by the device]

 When handling a conventional clip for grafting, it is relatively difficult to spread the clip by putting a finger on the slit and to spread it well over the entire length of the clip. Therefore, there is a problem in that the grafting work may take a long time, and the scooping work may be distracted and the scion may be damaged during the work.

An object of the present invention is to provide a grafting clip that can easily open and close the clip.

[0005]

[Means for Solving the Problems]

 To achieve the above object, a graft clip according to the present invention comprises the following graft clips. That is, a graft fixing part that is formed by forming a slit that extends over the entire length in the axial direction in the annular part and that can be expanded with the opposing part of the slit as a fulcrum part, and from both sides of the fulcrum part of the annular part A graft graft having a pair of extending handle portions, wherein the graft fixing portion and the handle portion are formed integrally with each other and made of an elastic material.

[0006]

[Action]

 Since the graft clip of the present invention has a pair of grips, the grips can be easily expanded by removing the applied force by sandwiching the grips with fingers and applying a force in the direction in which the pair of grips approach each other. Can easily reduce the diameter of the clip.

[0007]

【Example】

 A preferred embodiment of the graft clip of the present invention is shown in FIGS. As shown in FIG. 2, the grafting clip 2 is used for connecting and fixing the rootstock 4 and the scion 6.

As shown in FIG. 1, the graft clip 2 includes a graft fixing portion 10 and a grip portion 20. The graft fixing part 10 and the grip part 20 are integral with each other and are made of an elastic material such as rubber or plastic.

The graft fixing portion 10 is formed by forming a slit 14 on the annular portion 12 over the entire length in the axial direction. The connection part of the rootstock and the scion is inserted and grasped in the inner space of the annular part 12. The portion of the annular portion 12 that faces the slit 14 with an internal space therebetween constitutes a fulcrum portion 16, and the size of the slit 14 is increased or decreased with the fulcrum portion 16 as a fulcrum, whereby the graft fixing portion 10 is Scaled.

The grip portion 20 extends from both sides of the fulcrum portion 16 of the graft fixing portion 10 to the outside of the annular portion 12 and away from the slit 14. The pair of grip portions 20 are formed symmetrically with respect to a plane passing through the slit center and the fulcrum center. The inner side surface 22 of the handle portion 20 is tapered so that the distance increases as the distance from the slit 14 increases. The outer side surface 24 of the slit 14 extends in the tangential direction of the outer peripheral surface of the annular portion 12, and the pair of outer side surfaces 24 are parallel to each other.

Next, the operation will be described. The connection between the rootstock 4 and the scion 6 is cut diagonally to bring the cut surfaces into contact. Next, the grip 20 is pinched with the fingers of the clip 2 for grafting so as to open the clothespin, and the width of the slit 14 is expanded to expand the graft fixing part 10. Next, the connecting portion between the rootstock 4 and the scion 6 is put into the internal space of the graft fixing portion 10 through the slit 14, the gripping force of the handle portion 20 is removed, and the diameter of the graft fixing portion 10 is reduced by elasticity. The graft fixing part 10 fixes the connection between the rootstock 4 and the scion 6.

The expansion and the diameter reduction of the graft clip 2 are performed with the fulcrum portion 16 as a fulcrum. That is, when the pair of grips 20 are sandwiched by fingers and the grafting clip 2 is deformed in the direction in which the grips 20 approach each other, the fulcrum portion 16 is elastically deformed and the slit 14 expands in the grafting direction. The clip 2 is deformed. When the gripping force of the grip portion 20 is released, the clip 2 for grafting tends to return to its original state due to the elastic restoring force, and the rootstock 4 and the spikes 6 inserted therein are held and fixed from the outer periphery.

The expansion and diameter reduction of the above-mentioned graft clip 2 can be easily performed only by pinching the grip portion 20 with a finger or releasing the pinching. In other words, it is not necessary to pry fingers or nails into the slit to expand it as in the past, and it is not necessary to insert the rootstock and the scion into the clip through the slit partially blocked by the fingers or nails, so the work is easy. is there.

[0014]

[Effect of the device]

 According to the present invention, the graft graft is composed of a graft fixing part and a pair of grip parts, the slit facing part of the graft fixing part is a fulcrum part, and a pair of grip parts are provided on both sides of the fulcrum part outside the annular part. Since it is formed so as to extend toward, the scissor clip can be easily expanded and contracted by simply pinching the pair of grips or releasing the pinch, and there is no need to put a finger on the slit. Rootstocks and spikes can be easily put in the graft fixing part. Therefore, the grafting work time can be shortened.
