Abstract

PURPOSE:To provide a gripping face of a grafting clip having protrusions on the right and left side of the inner face of the gripping part having a groove for receiving the tip of a ring-shaped spring on the outer surface and positioning the protrusions of a gripping piece between the protrusions of the other piece. CONSTITUTION:This gripping face of the grafting clip for holding the grafting part of a scion and a stock cut at prescribed positions has the following structure. Clip pieces 4 having holding parts 2 on one end and openable parts 3 on the other end are placed opposite to each other interposing a rotation center 1 therebetween. A spring groove 6 is formed on the openable part 3 and a groove 8 for receiving the tip of a ring-shaped spring is formed on the outer face of the gripping part 2. Protrusions 9, 10 are formed on the left side and the right side of the inner face of the gripping part 2 and the protrusions on a gripping piece are positioned between the protrusions on the other piece.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gripping surface of a graft clip for gripping a joint between a scion seedling and a rootstock seedling cut at a predetermined position.

[0002]

2. Description of the Related Art A gripping surface is provided with a plurality of continuous convex portions from one end to the other end on the inner surface of the gripping portion for gripping a joint surface.

[0003]

However, since the gripping surface having the above-mentioned structure has a weak gripping force, the joint surface between the scion seedling and the rootstock seedling is easily separated, which causes a decrease in the survival rate.

[0004]

The present invention provides a gripping surface of a graft clip which can enhance the gripping force, and has taken the following technical means. That is, the clip pieces 4 and 5 having the grip portion 2 on one side and the opening / closing portion 3 on the other side are opposed to each other with the rotation center portion 1 interposed therebetween, and the spring groove 6 is provided in the opening / closing portion 3 and the outer surface of the grip portion 2 is provided. A groove 8 into which the tip of a ring-shaped spring 7 is inserted is provided, and convex portions 9 and 10 are provided on the left and right sides of the inner surface of the grip portion 2, and one convex portion is located between the other convex portions. The gripping surface of the graft clip. The configuration is as follows.

[0005]

When the opening / closing part 3 of the graft clip is pushed toward the approaching side, the gripping part 2 opens against the force of the spring 8 centering on the rotation center part 1. Then, when the joint surface between the scion seedling and the rootstock seedling is located between both gripping portions, the pushing into the opening / closing portion 3 is released. Then, both gripping parts 2 are closed by the restoring force of the spring 8, and at this time, the respective convex parts 9 and 10 grip the joint surface.

[0006]

[Effect] Since the positions of the convex portions 9 and 10 of the grip portion 2 are deviated, the gripping force on the joint surface of the grafted seedling becomes high, and the production efficiency of the grafted seedling can be improved.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. First, the structure thereof will be described. The graft clip 11 is provided with a pair of clip pieces 4 and 5, and a spring 7 having a ring shape and a discontinuous middle portion.
When viewed from the front, the clip pieces 4 and 5 are provided with a gripping portion 2 having a gripping surface on one side of the rotation center portion 1 and a vertically elongated opening / closing portion 3 on the other side. The part 2 and the opening / closing part 3 are integrally formed. In addition, the rotation center portion 1 is formed to be thickened by bulging inward, and the tip end portion is formed into a spherical shape, and the rotation protrusion having the axis in the lateral direction and the rotation protrusion holes 13 and 12 are formed. It is integrally provided in the middle part in the left-right direction in a side view.

The grip portion 2 is provided with a groove 8 into which the tip of the spring 7 is inserted on the outer surface, and convex portions 9 and 10 are provided on the inner surface at predetermined intervals on the left side and the right side, respectively. Then, one of the convex portions is arranged so as to be located between the other convex portions. In addition, in FIG. 4, a protrusion 14 is provided in the central portion, one end of the protrusions 9 and 10 is connected to the protrusion 14, and the protrusions 9 and 1 are connected.
If the length of the inner end portion of 0 overlaps, the gripping force can be increased.

The opening / closing portion 3 is provided with a spring groove 6 from the tip to the grip portion 2 which is slightly larger than the diameter of the spring 7. The graft clip 11 shown in FIG. 7 is made of polyporoprene (P / P), and integrally formed with a rotation center part 1, a grip part 2, an opening / closing part 3, and a thin plate-like connecting plate 15 for connecting both opening / closing parts 3. is doing. With this configuration, it is not necessary to assemble a spring separate from the clip piece, so that the production efficiency can be significantly increased.

Next, the operation will be described. First, the production of the graft clip 11 will be described. The gripping surfaces of the clip pieces 4 and 5 are opposed to each other, and the rotary projection 12 of the clip pieces 4 and 5 is fitted into the rotary projection hole 13 of the other clip. Then, attach the spring 7 to both clip pieces 4, 5
The tip portion is inserted into the groove 8 provided on the outer surface of the grip portion 2 through the spring groove 6 of.

Next, when performing the grafting work, when the opening / closing part 3 is pushed inward (on the approaching side), the gripping part 2 moves outward (centering on the turning center part 1) and opens. . After that, when the joint surface of the scion seedling and the rootstock seedling cut at a predetermined position and positioned between the open gripping portions is positioned, the opening / closing portion 3
Release the push. Then, the gripping part 2 grips the joint surface of the scion seedling and completes the grafting work while returning to the original position by the restoring force of the spring 7. Then, when the joint surface is gripped, the convex portions are located between the convex portions of the other side, so that the gripping force of the joint surface can be increased.
