葉との引掛りが無く接ぎ木精度を高め得る。The projections 7 are formed in the shape of an arc on the inner surface of the grip portion 2, formed long in the moving direction of the grafting clip 8, and provided at predetermined intervals in the horizontal direction. In FIG. 8, the distal end position of the protrusion 7 located at the lateral end is provided rearward in the moving direction of the graft clip 8 than the distal end position of the protrusion 7 located at the center. When cucumber seedlings are joined by single-leaf cutting and grafting, the joining position of the grafted clip 8 to the rootstock is about one-third of the cotyledon. Although it may be caught (see FIG. 9), this configuration can improve the grafting accuracy without catching the cotyledons.

部2の開き角αを大きく出来る。FIG. 14 and subsequent figures relate to the improvement of the center of rotation. That is, since the conventional bulging portion 12 is formed on an arcuate R surface as shown in FIG. 13, the rotating protrusion 13 easily comes out of the hole 14 (see FIG. 18). The opening angle β is also small (see FIG. 16). On the other hand, as shown in FIG. 14, the front end and the rear end of the bulging portion 12 are provided on the curved surfaces R1 and R2 and these two curved surfaces are connected horizontally. 12, the length C between the upper surface of the grip 12 and the outer surface of the gripper 2 can be increased.
The hooking between the opening 3 and the hole 14 becomes longer to prevent the opening 3 from coming off (see FIG. 17), and the opening angle α of the gripper 2 can be increased even if the opening angle of the opening / closing section 3 is the same.

とにより破損も防止し得る。Next, the operation will be described. An automatic graft clip feeding device, for example, a device for transferring the clip passage to a predetermined graft clip pushing position while arranging the clip passages in a line by using vibration (this means is described in the applicant of the present invention) When the spring 10 is pushed in the direction of the arrow, the graft clip 8 moves to the graft side, and in this connection, the opening / closing section 3 also has a guide plate having a width smaller than the opening width L (see FIG. (Not shown) and moves inward (in the direction of arrow A) about the rotation center 1 (see FIG. 1). Then, the gripper 2 is moved around the rotation center 1 by the spring 10.
(See FIG. 3). When the restriction on the opening / closing part 3 is released when the grip part 2 reaches a predetermined position, the grip part 2
Due to the restoring force of the above, it is rotated inward (opposite to the direction of the arrow) to hold the joint between the scion and the stock, completing the grafting operation.
When the opening / closing portion 3 moves inward, if the protrusion 4 is not present, the movement is prevented by the protrusion 4 before reaching the maximum movement. The space surrounded by a part of the outer surface of the spring 10 and a part of the outer surface of the opening / closing part 3 and the inner surface of the spring 10 can be reduced. Therefore, it is possible to prevent the other graft clip 8 from entering the space and to entangle the clips, so that the stability and efficiency of the grafting operation can be improved. In addition, since the opening of the grip portion 2 is restricted, the rotation projection 13 does not fall out of the hole 14 and damage can be prevented by reducing the overload on the spring 10.

When the operation pieces 9 are opposed to each other, the positions of the two projections 4 are different from each other when viewed from the side, so that only one operation piece 9 is required and the projections can have a sufficient height. Since the protrusion 6 is provided to make the groove 5 partially narrow, particularly at the end on the side opposite to the grip portion 2, the spring 10 of the other graft clip 8 is moved while the graft clip 8 is moving. To prevent intrusion into the groove. Accordingly, it is possible to prevent the grafting clips from being entangled with each other to improve the work efficiency of the grafting work, and to prevent the loss since the spring 10 remains in the groove 5 when the operating piece 9 is separated.

る。By forming the rotation projection 13 and the hole 14 of the graft clip 8 in a rectangular shape, each operating piece 9
The horizontal end surface flat portion of the rotary projection 13 is received by the flat surface of the hole 14 and is restricted from moving in the horizontal direction. Accordingly, there is no lateral displacement of the operation piece 9 and the gripping accuracy of the grip portion 2 can be improved. And
When the graft clip 8 moves to the grafting side (the side of the joint between the seedling and the rootstock), the gripping part 2 moves in the same direction as it is in an open state. Sometimes. However, since the projection 7 long in the moving direction is also formed in a mountain shape, the projection 7 does not slide and push the seedling even when it comes into contact. Therefore, the clamping accuracy of the binding work can be improved.
