Description of the Related Art A grafting apparatus using this spike clamping device is composed of a scion conveying conveyor for conveying a tray in which a plurality of seedling pots containing scion seedlings are arranged in a row, and a rootstock. A stock transfer conveyor for transferring trays in which a plurality of seedling pots containing seedlings are arranged in a row, and at a predetermined grafting processing position, The spikes are cut, and the spikes are automatically conveyed by the spike clamp device toward the bases from which the spikes have been cut and removed from the rootstock seedlings, and the spikes are clipped through grafting clips. It is a device that joins to the base. [0003] That is, a clip is applied to the tip of the pedestal, and the spike is inserted into the clip. At this time, if the center of the clip and the spike are slightly displaced, the inner diameter of the clip is reduced. Side will not be inserted well, resulting in an insertion error. As shown in FIG. 7, when cutting the spike portion 11a from the scion seedling 11, the seedling shaft 11b of the scion seedling 11 may be bent or the seedling shaft 11b may fall. However, if the seedling shaft 11b is cut while being bent in this manner, an insertion error may occur in a subsequent grafting process, for example, in a process of inserting the ear into the clip. For this reason, conventionally, the seedling shaft 11b is pulled upward by the scraping member 16 and extended, and then the seedling shaft 1b is pulled out.
1b was hardened by a spike clamp device (hereinafter, referred to as "clamp" ) and cut with a knife or the like. [0005] However, according to the above-described conventional means for extending the seedling shaft 11b, the seedling shaft 11 is utilized by utilizing the frictional force between the scraping member 16 and the spike portion 11a.
