Description of the Related Art FIG. 11 is an explanatory view showing a configuration example of a tuna longline fishery for explaining the present invention, FIG. 12 is an explanatory view showing a snap configuration, and FIG. 13 is an explanatory view showing a snap operation. In FIG. 11, 1 is a trunk rope, 2 is a snap, 3 is a floating cord, 4
Is a floating ball. 5 is a bran and 6 is a hook. Also, 7
Is the sea, 8 is tuna (fish), and 9 is a fishing boat. FIG. 12 shows the structure of the snap 2. One snap-like wire is used for the snap 2, and one end is bent into a key shape with a spiral wound around the center. At the other end, two parallel lines are formed by winding the folded end partway, and the formed parallel lines are raised in an S-shape and molded into the shape shown in the figure.

Reference numeral 10 denotes a winding portion of the snap 2, reference numerals 11 and 12 denote upper and lower arms, and reference numeral 13 denotes a helical portion which is spirally wound and applies an expanding force in a direction of separating the two arms 11 and 12. Further, 14 is a holding portion formed at the tip of two parallel lines of the lower arm portion 12, 15 is a stopper portion projecting upward from the holding portion 14, and 16 is a stopper portion of the holding portion 14 and the stopper portion 15. It is a key-shaped part formed at the tip of the interrupt arm 11 in between. An expanding force is applied to the arms 11 and 12 by the helical portion 13, but in the normal state, the vicinity of the tip of the arm 11 comes into contact with the stopper 16 to prevent expansion. In a normal state, the arcs of the key-shaped portion 16 and the holding portion 14 coincide with each other, so that a circular space in the orthogonal direction for holding the trunk rope 1 is formed.

When the gripping force is applied against the expanding force by gripping the holding portion 14, the relative position between the holding portion 14 and the key-shaped portion 16 is shifted as shown in FIG. 13A, and the holding portion 14 is opened. Then, when the snap 2 is slid in the direction of the arrow while the upper arm 11 side is along the trunk line 1, the trunk line 1 enters the holding portion 14.
At this time, by releasing the gripping force of the gripped arms 11 and 12, the trunk rope 1 is clamped by the expanding force of the holding portion 14 and the key-shaped portion 16, and the snap 2 is connected to the trunk rope 1. The connected state of the snap 2 is shown in FIG.

[0005]

Generally, in the tuna longline fishery as described above, the connection interval between the snaps 2 is 150.
If the length is long, the trunk rope 1 may reach several km to one hundred and several tens km. As shown in FIG. 11, a number of brans 5 with hooks 6 are connected to the long trunk line 1 via the snaps 2, and are drawn out into the sea. Therefore, approximately one thousand snaps 2 are connected by one tuna longline setting operation. Conventionally, such connection work of the snaps 2 has all been performed manually, which requires not only a great deal of labor but also pains and dangers in connection work of the snaps 2 on the ship in winter or in bad weather. And other problems.
