  When a shell suspended in the sea receives a wave and rotates or swings around the shell locking device D, the shell locking projection G of the shell locking device D is twisted and the depression (bed) I of the base material A They fall down and the shell B may get over the shell stop projection G of the shell locking tool D and fall off in the direction of arrow a, resulting in a decrease in the yield of the aquaculture and a decrease in the profit of the fisherman.

  The present invention provides a shell locking tool in which a shell stopper protrusion is unlikely to cut or fall down, and the shell does not fall out.

  According to claim 1 of the present invention, the elongated base material 1 that can be inserted into a hole formed in a rope and a shell comprises a shell stopper projection 2, a first rope stopper projection 3, and a shell stopper projection 2. 1 or two or more narrow retaining portions 4 having a narrow width, and the shell retaining projection 2 is projected from the axial end portion 5 side of the base material 1 to the first rope retaining projection 3 side. The base 1, the shell stop protrusion 2, the first rope stop protrusion 3, and the retaining part 4 are integrally formed of resin.

  The shell locking tool according to claim 2 of the present invention is the shell locking tool according to claim 1, wherein the tip of the locking portion 4 is connected to the butterfly 6a side of the shell 6 in the shell locking projection 2 and the locking portion 4. It is set as the length which protrudes to the outer side of the level | step-difference part 7.

  The shell locker according to claim 3 of the present invention is the shell locker according to claim 1 or 2, wherein the retaining portion 4 is linear, or the outer surface 2a side or inner surface of the shell protrusion 2 is provided. It is bent or bent toward the 2b side.

  The shell locker according to claim 4 of the present invention is the shell locker according to any one of claims 1 to 3, wherein the second rope stop protrusion 13 is opposite to the first rope stop protrusion 3. The second rope stopper protrusion 13 is formed so as to protrude and protrude at the base of the first rope stopper protrusion 3 or on the inner side of the tip.

  The collective shell locking tool according to claim 5 of the present invention has a large number of shell locking tools according to any one of claims 1 to 4 arranged at intervals in parallel, and a large number of shell locks. The both ends of the stopper in the axial direction are formed by being connected by the rigid connecting material 21.

  According to a sixth aspect of the present invention, there is provided a continuous shell locking tool in which a large number of the shell locking tools according to any one of the first to fourth aspects are arranged in parallel and spaced apart from each other. The base material 1 of the fastener is formed by being connected by a flexible connecting material 25 that can be wound in a roll shape.

  According to a seventh aspect of the present invention, there is provided a continuous shell locking tool in which a plurality of the continuous shell locking tools according to the sixth aspect are arranged in parallel and spaced apart from each other, and the first rope locking protrusion of the adjacent shell locking tool. 3 and the second rope stop projection 13 are connected and molded by a flexible connecting member 25 that can be wound in a roll shape.

  The roll-shaped continuous shell locking tool according to claim 8 of the present invention is obtained by winding the continuous shell locking tool according to claim 6 or claim 7 in a roll shape.

For this reason, the retaining portion and the shell retaining projection are not twisted, and the shell retaining projection does not lie down on the bed of the base material or cut from the root, and the shell does not fall off from the shell locking tool. If the retaining portion is long, it is easy to bend in the sea, and if it is bent, the shell is more difficult to fall off.

  In the shell locker according to claim 3 of the present invention, the retaining portion is linear, or is curved or bent on the outer surface side or inner surface side of the shell stopper projection. It has the same effect as the drop-off prevention, and the shell or shell is more difficult to drop off when bent or bent.

  The shell locking tool according to claim 4 of the present invention is formed by projecting and molding the second rope locking protrusion on the base material of the shell locking tool in a direction opposite to the first rope locking protrusion. Since the first rope stopper protrusion protrudes inward from the root or tip, the inclination angle θ of the first rope stopper protrusion is reduced as shown in FIG. Is wider than the interval m in FIG. 19 (a), the sliding width (shift width to the left and right) of the shell locking tool inserted into the rope is restricted by the second rope locking protrusion, and the shell locking is reduced. The tool is less likely to be displaced. For this reason, it becomes difficult for the first rope stopper protrusion to collide with the rope, the first rope stopper protrusion does not break, the shell locking tool does not come off from the rope and falls off, and the yield of the cultured shellfish is improved.

  The collective shell locking tool according to claim 5 of the present invention has a large number of the shell locking tools arranged in parallel at intervals, and the axial ends of the multiple shell locking tools are made of a rigid connecting material. Since they are connected and molded, a large number of sheets are stacked horizontally and stacked vertically, or vertically and vertically or horizontally, and set on a cutting and inserting machine (commonly called pin setter). Can be inserted into the rope while cutting one by one, and the insertion into the rope is automated, improving workability. In this case, if a number of shell locks are connected in the same direction, the shell locks are aligned in the same direction when they are separated one by one and inserted into the rope. It becomes easy to work. Because it is a connection with a rigid connecting material, when the collective shell locker is set on the automatic pin cutting machine and cut one by one, even if the collective shell locker is automatically fed, the adjacent shell The interval between the stoppers and the shape of the collective shell locker do not change, and the cutting and inserting work is stabilized.

The continuous shell locking tool according to claims 6 and 7 of the present invention has a large number of the shell locking tools arranged at intervals in parallel, and a plurality of shell locking tools are formed in a roll shape between the base materials. Since it is connected with a flexible connecting material that can be wound, the following effects are obtained.
(1) Even if there are many thousands or tens of thousands of shell locks, they can be rolled, stored, transported, and set on a pin setter. Convenient.
(2) If the flexible connecting material is made into a thin piece, the shell locking device can be easily separated and can be easily wound into a roll. Linked shell anchors that are continuously molded for several tens of meters or more may be entangled with rope stopper projections of shell anchors, or entangled with shell stopper protrusions depending on how they are stored or transported. It may be bent and difficult to pull out or separate one by one, but there is no such thing because of the protective sheet.

Since the roll-shaped continuous shell locking device according to claim 8 of the present invention is wound around the continuous shell locking device, the following effects are obtained.
In the case of a roll-shaped continuous shell locker in which a continuous shell locker is rolled around a bobbin, the bobbin can be rotated because the connected shell locker can be pulled out of the bobbin by setting the bobbin on the rotating shaft. It becomes smooth, and each shell locker is cut one by one, and the cut shell locker is smoothly inserted into the rope. Since the bobbin has a hook, it is possible to store and store the hooks rolled up in a roll shape, which is convenient for handling.

  Since the roll-like continuous shell locking device according to claim 9 of the present invention is wound in a roll shape with a protective sheet interposed, a large number of connected shell locking devices are not entangled with each other. The rewinding (drawer) of the stopper becomes smooth and easy to set on an automatic pin setter or the like, making it easier to use.
