Abstract

(57) [Summary] [Purpose] When grafting a scion on a rootstock, it is possible to cut at a stable optimum grafting angle with one hand operation, and
Improve the survival rate. [Structure] One of the forceps-like scissors is provided with a gutter into which a stem of a seedling is fitted and a receiver spaced apart from the upper end of the gutter. A cutting blade that penetrates between the upper end of the gutter and the receiving body is configured to be mounted via an adjustable holder.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to scissors for grafting, in which the grafting surface of the rootstock and the scion is cut when the grafting is grafted to the rootstock.

[0002]

[Prior art]

 Conventionally, when a scion is grafted to a rootstock, as in JP-A-60-9421, JP-A-63-98323, and JP-A-63-226219, the surface of the rootstock and the scion is grafted. It is already known to hold a sapling in the left hand and hold a cutting tool in the right hand to cut the bevel by observing the tilt angle visually.

[0003]

[Problems to be solved by the device]

 The known ones described in JP-A-60-9421, JP-A-63-98323, JP-B-63-226219 and the like are known as the rootstock and the rootstock when grafting a scion on the rootstock. When cutting the sloping surface of the scion, the sapling is held with the left hand, the cutting tool is held in the right hand, and the angle of inclination is visually determined to cut the cutting. However, the inclination angles of the cut surfaces were uneven and not constant, the crimpability of the graft part was poor, and the survival rate was poor.

[0004]

[Means for Solving the Problems]

 According to the present invention, one of the forceps-like scissors is provided with a gutter into which a stem of a seedling is fitted, and a receiver spaced apart from the upper end of the gutter. The above-mentioned problem was solved by mounting a cutting blade that penetrates between the upper end of the gutter and the receiver via a holder whose angle can be adjusted.

[0005]

[Action]

 When grafting a scion on a rootstock, when cutting the grafting surface of the rootstock and the scion at an angle, open the two rods of the scissors to pinch the seedling, and inside one of the rods and the receiver. Along the stem stem of the seedling, the cutting blade on the other side of the rod can be inserted between the upper end of the gutter and the receiver to cut at a required inclination angle. In addition, the holder that holds the cutting blades can be rotated slightly with respect to the axis of the child rod to adjust the angle and fix it, so that the optimum grafting angle for the crop can be accommodated.

[0006]

【Example】

 An embodiment of the present invention will be described with reference to the drawings. The scissors 1 for grafting is composed of a child rod 2 and a child rod 3, and a forceps structure is formed by intersecting with a fulcrum 4 in front.

At the tip of one of the child rods 2, a receiving gutter 5 having a semi-circular cross-section that opens inward is fixed at a position corresponding to a position of a holder 7 described later so as to intersect the length direction of the child rod 2. The receiver 6 is extended to the upper end of the gutter.

The crossing angle between the child rod 2 and the gutter 5 is held by inserting fingers into the annular portions 2a and 3a of the base portion, and the stem and the gutter 5 in the longitudinal direction with the gutter close to the seedling. The receiving body 6 has a slender annular shape that is substantially parallel to the rod 2 and has a vertical gap, and the center of the receiving body 6 is aligned with the extension line inside the semicircular cross section of the gutter 5. It is bent to form a receiving portion 6a. Further, the receiving body 6 has such a length that, when the holder 7 enters, a length that allows the holder 7 to sufficiently pass therethrough, and a width that allows the holder 7 to sufficiently pass even if the inclination angle of the holder 7 with respect to the axis of the child rod 3 slightly changes. Is configured to hold the gap.

There is a stepped portion 3b in the middle on the side of the other child rod 3, the tip of which has a circular cross section with a small diameter, the boss portion 7a of the holder 7 is loosely fitted, and the screw portion 3c at the shaft end is fitted with a nut 8. By tightening, the holder 7 is fixed to the axial center of the child rod 3 while maintaining a required inclination angle, that is, a cutting angle.

As described above, the holder 7 is formed by one plate that encloses the small diameter portion of the child rod 3, and the two plates on the inner edge 7b side have a strong tightening force such as a spring force. It has a sharp cutting blade 9 such as a safety razor.

Now, when grafting a scion on a rootstock, when cutting the grafting surface of the rootstock and the scion with inclination, both scoops 1 and 2 of the scissors for grafting 1 are opened to sandwich the seedling, By arranging the inside of the gutter 5 on the second side and the receiving portion 6a along the stem trunk of the seedling and closing the rod 3 on the other side, it is possible to cut at a required inclination angle. Since the optimum grafting angle differs depending on the crop, loosen the nut 8 at the tip of the lever 3 and slightly rotate the holder 7 with respect to the axis of the body of the lever 3 to adjust the angle, then fix it again with the nut 8. By doing so, the grafting angle can be changed. Further, the cutting blade 9 is clamped by the clamping force of the two plates of the inner edge portion 7b of the holder 7, but since it is movable in the longitudinal direction, the cutting position can be set without cutting only at the same position. Since it can be moved and used, the life of the cutting blade 9 can be extended.

[0012]

[Effect of device]

 According to the present invention, one of the forceps-like scissors 2 is provided with a gutter 5 into which a stem of a seedling is fitted, and a receiver 6 having a narrow space between the upper end of the gutter 5 and the other gutter. A cutting blade 9 which penetrates between the upper end of the gutter 5 and the receiver 6 is attached to the gutter 3 through a holder 7 whose angle can be adjusted. The position of the scissors with respect to the length direction of the blade is specified, and the cutting blade 9 with the angle set in this state cuts, making it possible to cut with a stable optimum grafting angle with one hand operation. Adhesion between the cut surface of the tree and the scion is improved, and the survival rate and work efficiency can be improved.
