Abstract

PURPOSE:To obtain the subject clip resistant to the displacement of the clamping part and smoothly movable to a prescribed position by attaching a plurality of protrusions in specific state to the clamping faces of a pair of openable clamping parts. CONSTITUTION:Plural protrusions 5, 6 are formed on the clamping faces 3, 4 of a pair of openable clamping parts 1, 2 and the distance between the protrusions is made to be somewhat larger than the width of the opposite protrusions. When the clamping parts are closed from the opened state, the protrusion on a clamping face is inserted into the gap of the opposite protrusions which is somewhat wider than that of the protrusions.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a graft clip used for grafting work.

[0002]

2. Description of the Related Art A center of rotation is provided at an intermediate part, a grip is provided on one side of the center of rotation, and an opening / closing part is provided on the other side, and the ring is pushed toward the "closed" side. And a push ring having elasticity.

[0003]

[Problems to be Solved by the Invention] However,
When the push ring is deformed, the gripping part may shift to the left or right, but when it is fed by the automatic clip feeder, it becomes clogged in this device and causes a graft error.

[0004]

The present invention provides a graft clip that can be smoothly moved to a predetermined position, and has taken the following technical means. That is, it has a pair of grips 1 and 2 that can be opened and closed.
A plurality of projections 5 and 6 are provided on the gripping surfaces 3 and 4, and the length between the projections is slightly larger than that of the mating projection.

[0005]

When the grips 1 and 2 change from the "open" state to the "closed" state, the projections 5 and 6 provided on the gripping surfaces 3 and 4 are fitted into the gaps between the mating projections that are slightly wider than the projections. ..

[0006]

[Effect] Since the displacement of the grip portions 1 and 2 in the lateral direction with respect to the opening / closing direction is small, the graft clip can be smoothly supplied to a predetermined position, and the grafting work efficiency 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 7 has a rotation center portion 8 in an intermediate portion, and gripping portions 1 and 2 are provided on one side of the rotation center portion 8 and an opening / closing portion 9 is provided on the other side. Further, it is provided with a pressing ring 10 having a ring-like elasticity that constantly pushes the gripping parts 1 and 2 toward the “closed” side.

The gripping surface 3 of the gripping portion 1 is provided with a large number of projections 5 having a spherical surface at the tip, and the gripping surface 4 of the gripping portion 2 is provided with projections 6 having a spherical surface at the tip. Many are provided in zigzag. The protrusions 3 and 4 are arranged so that the protrusion spacing is slightly wider than that of the protrusion 5 or the protrusion 6, and the protrusions 5 and 6 can be fitted between the counterpart protrusions when the grips 1 and 2 are closed.

Next, the diameter of the stem or the stem of the scion may differ depending on the product type, and the size of the graft clip may be changed as a means for dealing with this. But,
When grafting clips are made manually, it is good, but when they are made by an automatic feeder, a device suitable for their shape must be used. This increases the burden on the operator and is not practical.

In the graft clip of FIG. 3, the outer shape is substantially the same, and the same automatic feeding device can be used by changing the size of the space between the holding surfaces of the holding portions 1 and 2. In addition, if each connecting clip 7 of a type with a different size of its space is color-coded (other large, medium, small, S, M, L, etc.) can be identified, it will be wrong when used. There is no.

If the tip of the gripping portion 1 (2) is rounded as shown in FIG. 4, the graft clip 7 can move smoothly and the grafting work efficiency can be improved. Next, the operation will be described. First, when the opening / closing section 9 is pushed inward (the pushing means may be automatic or manual), the gripping sections 1 and 2 move in the opposite direction to the gripping surfaces 3 and 4.
open. Then, when the graft clip 7 reaches the junction of the rootstock and the scion in this state, the pushing action on the opening / closing portion 9 is stopped. Then, the gripping parts 1 and 2 are closed by the force of the pressing ring 10 and grip the joint part by the gripping surfaces 3 and 4.

When the graft clip 7 is moved, since the projections 5 and 6 having spherical ends on the gripping surfaces 3 and 4 are fitted between the mating projections, both gripping surfaces 3 and 4 are laterally moved. It can be prevented from slipping in and moves smoothly.
