That is, first, in the ear suspension device according to the first or second aspect of the present invention, since the attachment of the locking tool to the rope and the attachment of the juvenile to the locking tool are performed substantially at the same time, the work efficiency is improved. Is good. In addition, since two fry shells are attached to the locking tool at the same time, this also improves work efficiency. In addition, in the ear suspension device according to claim 3, in addition to this, when the drill portion retreats and rises after drilling, the fastener is chased by the drill portion so that the fastener is inserted into the through hole by the fastener supply portion from below. Pierced. Therefore, since the locking tool can be pierced through the through hole of the rope formed by twisting the fiber before closing, the failure rate of piercing is remarkably small. Further, in the ear suspension device according to claim 4, since the locking tool has a simple shape in which a pair of juvenile locking parts are provided at both ends of the locking tool body having a substantially rod shape or in the vicinity thereof, Its molding is simple. When the grown scallop is pulled strongly to remove it from the rope, the locking body is torn at some point in the longitudinal direction, and the locking state of the locking tool with respect to the rope is released. Therefore, the entire fastener can be easily removed from the rope without further cutting the fastener body elsewhere. Further, in the ear suspension device according to the fifth aspect, since a large number of the locking tools are gathered as a sheet-shaped cartridge, the handling such as loading is easy. Further, in the ear suspension device according to claim 6 or 7, when positioning the juvenile shell on the shell, the concave corner portion between the shell main body portion and the ear portion of the juvenile is used as the juvenile shell positioning portion for opening one piece. Just by bringing them into contact with each other, it is possible to easily open one piece suitable for growing juveniles.
