Description

  The present invention relates to a lashing tool for tightly tying a lattice frame of cocoons such as oysters made of 孟 mune bamboo.

  Oysters are made by combining Munetake bamboo, etc. in a lattice, tightly tying the lattice with wire, and attaching a float such as styrofoam to the bottom. For the assembly of oysters, for example, Munetake bamboo is arranged in a grid of about 10m in length and about 20m in width, and a thick wire with a diameter of about 4mm is wound around the lattice part, and the wire is twisted by the operator's tool. It is done by fixing. Specifically, the wire is fixed as follows. The wire for lashing is a hairpin shape obtained by cutting a normal wire into a certain length, aligning both ends, and bending it into a U-shape. The chopping tool is a tool in which a tapered portion that is narrowed toward the tip is provided at the tip of the gripping portion, and has been conventionally used for wire lashing. The operator winds the wire around the lattice portion so that the U-shaped portion and the other end of the wire face upward, passes the tool in the U-shaped portion, and pulls up the other end of the wire by hand. Next, the operator hooks the tip of the tool on the wire that is being pulled up, simultaneously rotates the tool in one direction, and winds the wires together to firmly bind the lattice portion.

  To perform such work, a great force is required. In addition, oysters usually have about 450 lattice parts per unit, and a lot of labor is required for tying work. Oyster tying is a difficult task for women, the elderly, etc., because it requires hard work and at the same time requires heavy work. Further, since skilled techniques are required for handling the chopping tools, the number of workers is limited. Furthermore, since the work on the cage is unstable and the workability is poor, a tool that can be easily secured is desired.

  So far, tools for easily binding wires have been proposed. For example, there is a wire binding tool in which a rotor having a spiral groove on the outer periphery and a C-shaped hook at the tip is disposed on a cylindrical stator, and the rotor is rotated only in one direction to twist the wire (for example, Patent Document 1).

Japanese Patent Laid-Open No. 2001-9751

  In the tool described in Patent Document 1, when binding the binding portion with a wire, it is necessary to twist the wire by hand in advance to create a twisted portion for hooking the C-type hook, and a strong force is required. Further, the operator pulls the stator upward at the middle waist and twists the wire with the C-shaped hook. Therefore, the work posture becomes unstable, and there is a risk of injury if the hand slips.

  An object of the present invention is to provide a lashing tool that does not require a large force and can quickly proceed with lashing work when tying a lattice portion of a ridge formed by laying a bamboo sword bamboo or the like in a lattice shape. It is.

  The present invention is a scissor securing tool for rotating a chopping tool and binding a lattice-shaped part of a scissors with a wire, the upper holding plate having a bearing part of a rotating shaft in the central part, and a rotating shaft in the central part. A lower holding plate having a bearing portion and attached to the lower portion of the upper holding plate with a predetermined interval, and a through-hole through which the wire is inserted into the center portion are rotatably fitted in the two bearing portions. A pipe-shaped rotating shaft, a ratchet gear that rotates integrally with the rotating shaft, a main body gear that is rotatably fitted to the rotating shaft, and a movable that transmits rotational movement in one direction of the main body gear to the ratchet gear. A claw, a fixed claw for preventing the ratchet gear from rotating in a direction opposite to the rotation direction, a lever gear that meshes with the main body gear and rotates the main body gear, and the lever rotatably attached to the upper holding plate Rotate gears in forward and reverse directions A manual lever, a tool attachment for attaching a tool that is fixed to the rotary shaft below the lower holding plate and rotates integrally with the rotary shaft, the upper holding plate, and the lower holding plate A lashing tool comprising: a handle provided on a side of the handle; a presser provided at a rear end of the handle; and a wire gripping tool that sandwiches a wire protruding above the upper holding plate. It is.

  Further, the present invention provides the above-described lashing tool, which is further attached to the above-mentioned tool mounting tool, further comprising a tapered portion that is thinner toward the tip and a cylindrical portion having the same thickness provided at the tip of the tapered portion. It is characterized by comprising a tool for use.

  Moreover, the present invention is characterized in that, in the lashing tool, a diameter of the lever gear is smaller than a diameter of the main body gear.

  According to the present invention, in the lashing tool, the tool mounting tool is a tool in which the tip of the chopping tool faces downward and the axis of the chopping tool is inclined by 5 to 15 degrees with respect to a horizontal plane. It is characterized by being attached.

  Further, the present invention is characterized in that, in the lashing tool, the tool attachment tool attaches the tool so that the axis of the tool is displaced with respect to the center of the through hole of the rotating shaft in plan view. And

  Further, the present invention is characterized in that, in the lashing tool, the tool attachment tool includes a plurality of attachment openings for attaching the tool in the circumferential direction.

  Further, the present invention is the lashing tool, wherein the wire gripping tool is a pliers type that sandwiches the wire by two members, or a roller type wire gripping tool that sandwiches the wire by two rollers, and the wire gripping tool It is characterized in that the wire protruding above the upper holding plate is sandwiched, the wire is pulled upward, and the wire can be removed.

  According to the present invention, in the lashing tool, the roller-type wire gripper further includes an electric motor that rotates the roller.

  Further, according to the present invention, the lashing tool includes an electric motor that rotates the lever gear instead of the manual lever.

  In the lashing tool of the present invention, when the tool is attached to the sword tool attachment and the manual lever is rotated, the sword tool rotates in one direction via the lever gear, the main body gear, and further the ratchet gear. Therefore, it is possible to easily and firmly bind the lattice portion of the ridge with a wire. Further, by increasing the length of the manual lever, the lever effect is increased, and the wire can be firmly bound by a light manual lever operation. The operation of rotating the manual lever is easy to operate and can be easily operated with one hand. The conventional method of tying a wire with a conventional tool is not only a heavy labor, but also requires skilled skills, but this lashing tool does not require any special technique for use, and can be used by ordinary workers. But lashing can be done easily.

  Further, according to the present invention, when the wire is tied up, the wire is provided with a sword tool having a tapered portion that is narrowed toward the tip and a cylindrical portion of the same thickness provided at the tip of the taper. Since the U-shaped part of the wire passed through the tool slides on the tapered part and moves to the cylindrical part, it easily approaches the wire on the other side, the interval between the wires to be bound is narrowed, and the wire is easily bound with a weak force. I can do it.

  Further, according to the present invention, since the lever gear has a smaller diameter than that of the main body gear, the lever effect can be increased and a strong tightening force can be applied to the tool. If you increase the lever effect simply by lengthening the manual lever, the long manual lever may interfere with the operability, but the manual operation with good operability can be achieved by optimizing the diameter ratio between the lever gear and the main unit gear. By selecting the lever length, a practical lever effect can be obtained and the wire can be tightened firmly. Therefore, even a weak person such as a woman can easily work.

  Further, according to the present invention, the sword tool mounting tool attaches the tool so that the tip part of the sword tool faces downward and the axis of the sword tool tilts from 5 degrees to 15 degrees with respect to the horizontal plane. The tip of the tool can catch and wrap the wire just above the lattice part of the cage. For this reason, it can be firmly secured with a small number of windings.

  Further, according to the present invention, the stool tool fixture is mounted in a plan view so that the tool tool is attached so that the axis of the sword tool is displaced with respect to the center of the through hole of the rotating shaft. The lashing work can be performed immediately without hitting the wire on the other side.

  Also, according to the present invention, the shino tool attachment includes a plurality of attachment openings for attaching the shino tool in the circumferential direction, so that the tip of the shino tool is attached to the attachment opening where the mating wire is wound. By attaching, the frequency | count of operation of a manual lever can be reduced and a wire can be tied up efficiently.

  Further, according to the present invention, the wire gripping tool is a pliers type that sandwiches the wire by two members, or a roller type wire gripping tool that sandwiches the wire by two rollers, and protrudes above the upper holding plate by the wire gripping tool. It is possible to pinch the wire to be pulled up and lift the wire upward to remove the looseness of the wire. Therefore, the wire can be firmly bound with the wire without the wire loosening, and the number of windings can be reduced.

  According to the present invention, since the roller-type wire gripper includes the electric motor that rotates the roller, the labor for pulling up and loosening the wire is unnecessary, and the workability is improved. Moreover, even people with weak power can easily perform lashing work.

  Further, according to the present invention, since the electric motor for rotating the lever gear is provided instead of the manual lever, the lever operation is not required and the lashing operation can be performed easily.

It is a perspective view which shows the whole structure of the oyster lashing tool 1 installed in the oyster as 1st Embodiment of this invention. It is a perspective view which shows the structure inside the oyster lashing tool 1 of FIG. It is a figure which shows the ratchet mechanism provided with the ratchet gearwheel 11, the movable nail | claw 9, and the fixed nail | claw 13 of the oyster lashing tool 1 of FIG. It is a top view of the oyster lashing tool 1 of FIG. FIG. 2 is a plan view of a sword tool 17 used for attachment to the oyster lashing tool 1 of FIG. 1. It is a perspective view which shows the whole structure of the oyster lashing tool 2 installed in the oyster as 2nd Embodiment of this invention.

  FIG. 1 is a perspective view showing an overall configuration of an oyster lashing tool 1 installed in an oyster as a first embodiment of the present invention. FIG. 2 is a perspective view showing an internal configuration of the oyster lashing tool 1. FIG. 3 is a view showing a ratchet mechanism including the ratchet gear 11, the movable claw 9 and the fixed claw 13 of the oyster lashing tool 1, with the upper holding plate 31, the main body gear 7 and the first plate 65 removed, It is the figure seen from. FIG. 4 is a plan view of the oyster lashing tool 1. FIG. 5 is a plan view of a sword tool 17 used for attaching to the oyster lashing tool 1. FIG. 1 shows a state in which a part of the side plate 35 is removed so that the inside can be seen.

  In general, the oyster lashing tool 1 rotates the manual lever 3 to rotate the tool 17 in one direction via the lever gear 5, the main body gear 7, and the ratchet gear 11. This is a tying tool that firmly binds the wire 21 attached to the lattice portion of the sword bamboo 19 with the rotating tool 17.

  The oyster lashing tool 1 includes an upper holding plate 31 and a lower holding plate 33, and the upper holding plate 31 and the lower holding plate 33 are formed in two left and right blocks so that a predetermined interval is formed therebetween. The spacers 34a and 34b are attached. A circular side plate 35 is provided inside the two spacers 34a and 34b. The upper holding plate 31 is fitted with a central shaft 37 of the ratchet gear 11 in the central portion, and a bearing portion 39 is formed to hold the ratchet gear 11 rotatably. A lever gear shaft 41 of the lever gear 5 is formed at the end. A bearing portion (not shown) is provided for fitting and holding this rotatably. The lower holding plate 33 is fitted with a central shaft 37 of the ratchet gear 11 at the center thereof, and a bearing portion (not shown) for holding the ratchet gear 11 rotatably is drilled, and a lever gear shaft 41 is fitted at the end. And a bearing portion 45 for holding it rotatably is formed.

  The manual lever 3 drives the lever gear 5 that meshes with the main body gear 7, and includes a grip rod 61 and an operation rod 63. The grip rod 61 is rotatably attached to the operation rod 63, and the manual lever 3 can be easily rotated by grasping the grip rod 61 with a hand. The operation rod 63 has a tip fixed to the upper end of the lever gear shaft 41 protruding from the upper holding plate 31. The operation rod 63 is not limited to a specific length. Since this effect can be increased by increasing the length, the length may be determined in consideration of the operability of the manual lever 3.

  The lever gear 5 rotates integrally with the manual lever 3 and rotates the meshing main body gear 7. The lever gear 5 is rotatably mounted between the upper holding plate 31 and the lower holding plate 33 both clockwise and counterclockwise via the lever gear shaft 41. The diameter of the lever gear 5 is smaller than the diameter of the main body gear 7. By making the diameter of the lever gear 5 smaller than the diameter of the main body gear 7, the lever effect can be increased. By simply moving the manual lever 3 lightly, the lever gear 5 can be transmitted to the main body gear 7 by changing it to a large force. If the manual lever 3 is simply lengthened and the lever effect is increased, the long manual lever 3 may interfere with the operability, but the diameter ratio between the lever gear 5 and the main body gear 7 is made appropriate, By selecting the length of the manual lever 3 with good operability, the wire 21 can be firmly bound with a small force. Therefore, even a weak person such as a woman can easily work. A gear may be further attached between the lever gear 5 and the main body gear 7 in order to make the rotation directions of the manual lever 3 and the main body gear 7 coincide.

  The main body gear 7 is rotatably fitted to the central shaft 37 of the ratchet gear 11 and is positioned between the upper holding plate 31 and the lower holding plate 33. A first plate 65 is attached to the lower surface of the main body gear 7, and a second plate 67 is attached below the first plate 65 at a constant interval. The main body gear 7 and the first plate 65 and the second plate 67 rotate integrally.

  The main body gear 7 meshes with the lever gear 5 and rotates clockwise and counterclockwise as the manual lever 3 is rotated. Accordingly, the first plate 65 and the second plate 67 rotate integrally, but a stopper 64 is provided so as to be rotatable only within a range of 90 °. When rotated counterclockwise, the first protrusions 66 of the first plate 65 and the second plate 67 contact the stopper 64, and when rotated clockwise, the second protrusions 68 of the first plate 65 and the second plate 67 are rotated. Comes into contact with the stopper 64. By providing the stopper 64, the contact with the lever gear 5 such as the first plate 65 is prevented, and the lever gear 5 is prevented from being damaged.

  The ratchet gear 11 includes a central shaft 37, and the central shaft 37 is rotatably fitted in the bearing portion 39 of the upper holding plate 31 and the bearing portion of the lower holding plate 33. The rotating shaft 37 is provided with a through hole 75 through which the wire 21 is inserted at the center, and is attached so that the lower end slightly protrudes from the lower holding plate 33. The ratchet gear 11 includes a movable claw 9 and a fixed claw 13 and constitutes a ratchet mechanism. In this embodiment, the ratchet gear 11 and the central shaft 37 are integrally formed. However, the ratchet gear 11 and the central shaft 37 may be separately manufactured and fixed. In the present embodiment, the central shaft 37 is the rotation shaft 37.

  The movable claw 9 has a rear end attached between the first plate 65 and the second plate 67 via a support pin 43 so that the front claw can be swung. The claw at the tip of the movable claw 9 is pressed against the tooth surface of the ratchet gear 11 by a spring plate 69. The movable claw 9 moves integrally with the main body gear 7, and when the main body gear 7 rotates clockwise, the claw at the tip engages with the teeth of the ratchet gear 11 to rotate the ratchet gear 11. On the contrary, when the main body gear 7 rotates counterclockwise, the tip of the movable claw 9 slides on the tooth surface of the ratchet gear 11 and the ratchet gear 11 is not rotated. Note that the rotation direction of the ratchet gear 11 may be reversed.

  The fixed claw 13 is attached to the lower part of the upper holding plate 31 via a support pin 44 so that the front claw can swing. The tip of the fixed claw 13 is pressed against the tooth surface of the ratchet gear 11 by a spring plate 71. Unlike the movable claw 9, the fixed claw 13 does not move integrally with the main body gear 7, and when the main body gear 7 rotates clockwise, the claw at the tip slides on the tooth surface of the ratchet gear 11. Conversely, when the main body gear 7 rotates counterclockwise, the tip of the fixed claw 13 is engaged with the teeth of the ratchet gear 11 so that the ratchet gear 11 does not rotate. Note that the rotation direction of the ratchet gear 11 may be reversed.

  When the operator brings the manual lever 3 close to the handle 25, when the manual lever 3 is rotated counterclockwise in FIG. 1, the rotational movement of the main body gear 7 is transmitted to the ratchet gear 11 via the movable claw 9. Conversely, when the manual lever 3 is moved away from the handle 25 and the manual lever 3 is rotated clockwise in FIG. 1, the main body gear 7 and the movable claw 9 are rotated in reverse, so that the rotational motion is transmitted to the ratchet gear 11. I can't. Moreover, since the reverse rotation of the ratchet gear 11 is prevented by the fixed claw 13, the ratchet gear 11 can be rotated only in one direction.

  The chopping tool fixture 15 is for attaching the chopping tool 17 and is bolted to the central shaft 37 of the ratchet gear 11 protruding from the lower holding plate 33. The chopping tool fixture 15 includes three chopping tool mounting plates 73 provided with mounting holes 74 for inserting and fixing the chopping tool 17 in the circumferential direction. Here, three examples of the tool mounting plate 73 are shown, but the number is not particularly limited. By providing a plurality of attachment openings 74 for inserting and fixing the knitting tool 17, the tip of the knitting tool 17 can be brought close to the winding side of the counterpart wire 21. Since the tool mount 15 rotates only in one direction, when the tip of the tool 17 is positioned on the counter-winding side of the counterpart wire 21, the tool 17 until the wire 21 is wound is placed on the counterpart wire 21. It is necessary to move to the winding side. By selecting the attachment port 74 close to the winding side of the counterpart wire 21, manual lever operation can be reduced, and the wire 21 can be secured efficiently.

  Further, since the sword tool mounting tool 15 mounts the tip of the sword tool 17 obliquely downward, the sword tool mounting plate 73 is arranged so that the axis of the sword tool 17 is inclined 5 to 15 degrees with respect to the horizontal plane. Is attached. By attaching the tip of the sword tool 17 obliquely downward, the tip of the sword tool 17 catches and winds the wire 21 directly above the oyster sushi bamboo 19 so that the tying operation can be completed quickly with a small number of windings. it can.

  In addition, the sword tool mounting tool 15 is a tool mounting plate 73 so that the axis of the sword tool 17 is displaced from the center of the through hole 75 of the center shaft 37 when the sword tool 17 is mounted in plan view. Is attached. By doing so, when attaching the sword tool 17, it is possible to perform the lashing operation immediately without hitting the counterpart wire 21.

  The second tool 17 has a taper portion 77 that narrows toward the tip after the grip portion 76 and a cylindrical portion 79 of the same thickness provided at the tip of the taper portion. A concave groove 80 is provided between the gripping portion 76 and the taper portion 77, and the concave groove 80 fits into a ball plunger provided in the attachment port 74 when the knives tool 17 is attached to the tool attachment 15. Fixed. By forming the chopping tool 17 in the above shape, the U-shaped portion of the wire 21 passed through the chopping tool 17 moves to the cylindrical portion 79 by sliding the taper portion 77 when the wire 17 is tied. The wire 21 approaches the side wire 21 and the interval between the wires 21 to be bound is narrowed, so that the wire 21 can be easily wound with a weak force.

  The oyster lashing tool 1 is provided with a handle 25 for holding the oyster lashing tool 1 by hand during use. The handle 25 is a pipe-like member that can be easily held by hand, and its tip is fixed to the spacer 34a. The handle 25 has a storage portion 26 for the tool 17 inside, and the tool 17 can be stored by inserting the tool 17 from the rear end.

  A foldable bar-shaped presser 81 is attached to the rear end of the handle 25. In FIG. 1, when the operator rotates the manual lever 3 forward and counterclockwise, the tool 17 winds the wire 21 while rotating clockwise. At this time, since the oyster tying tool 1 also tries to rotate counterclockwise, it is necessary to fix the handle 25 firmly in order to rotate the manual lever 3 counterclockwise. The handle 25 can be easily fixed by hooking the presser 81 on the sword bamboo 19.

  A wire gripping tool 23 is attached to the upper part of the upper holding plate 31. The wire gripping tool 23 is for gripping the wire 21 protruding from the through hole 75 of the central shaft 37. The wire gripping tool 23 has a structure like a tool pliers, and includes a push bar 83 and a receiving plate 85. The wire 21 is sandwiched between the push bar 83 and the receiving plate 85. The push rod 83 is attached to the upper holding plate 31 via a support pin 84 provided near the tip, and the push rod 83 is rotatable about the support pin 84. The receiving plate 85 is fixed immediately beside the through hole 75 of the central shaft 37. When the handle 25 and the push rod 83 are gripped so as to approach each other, the tip end portion 86 of the push rod 83 approaches the receiving plate 85 and sandwiches the wire 21.

  A method of using the oyster lashing tool 1 will be described. The operator uses a hairpin-shaped wire 21 in which one wire is bent at the center and a U-shaped portion is provided, so that the U-shaped portion and the end portion face upward on the lattice portion of the 孟 jong bamboo 19 arranged in a lattice shape. Wrap. Thereafter, the operator moves the oyster lashing tool 1 onto the wire 21 for binding. Attach the tool 17 to the tool attachment 15 and pass the U-shaped portion of the wire 21 at the same time. On the other hand, the end portion of the wire 21 is passed through the through hole 75 of the central shaft 37 so that the end portion protrudes from the upper holding plate 31. The wire 21 protruding from the upper holding plate 31 is gripped by the wire gripping tool 23, the rear side of the handle 25 is lifted, and the wire 21 is lifted to eliminate looseness. At this time, the tool attachment 15 on the opposite side of the handle 25 serves as a fulcrum, and the wire 21 can be pulled up with a small force.

  Next, when the manual lever 3 is rotated counterclockwise, the main body gear 7 is rotated clockwise via the lever gear 5. The rotational movement of the main body gear 7 is transmitted to the ratchet gear 11 through the movable claw 9. On the other hand, when the manual lever 3 is rotated clockwise, the main body gear 7 rotates counterclockwise. However, since the movable claw 9 slides on the tooth surface of the ratchet gear 11, the rotational movement of the main body gear 7 is not transmitted to the ratchet gear 11. . When the manual lever 3 is rotated, the tool attachment 15 and the tool 17 attached to the central shaft 37 of the ratchet gear 11 are rotated clockwise, and the U-shaped portion of the wire 21 is moved to the other wire 21. Wrap around and tightly tie up the grid.

  FIG. 2 is a perspective view showing the overall configuration of the oyster lashing tool 2 installed in the oyster as the second embodiment of the present invention. 2 shows a state in which a part of the side plate 35 is removed so that the inside can be seen, as in FIG. The same components as those of the oyster lashing tool 1 shown in the first embodiment are denoted by the same reference numerals and description thereof is omitted. The basic configuration of the oyster lashing tool 2 shown in the second embodiment and the oyster lashing tool 1 shown in the first embodiment are the same. While the oyster lashing tool 1 shown in the first embodiment is a pliers-like wire gripper 23, the oyster lashing tool 2 shown in the second embodiment employs a roller-type wire gripper 87. .

  The roller-type wire gripper 87 is an electric wire gripper and includes an electric motor 91, a worm 92, a worm wheel 93, an electric roller 95, and a presser roller 97. The electric roller 95 is rotatably mounted on the upper holding plate 31 just beside the through hole 75 of the central shaft 37 via a bearing base 96. A worm wheel 93 is attached to one end of the central axis of the electric roller 95, and a gear 88 for driving the presser roller 97 is attached to the other end. The electric motor 91 is fixed on the upper holding plate 31 via a mounting base 89 and rotates the electric roller 95 via a worm 92 attached to the tip.

  The presser roller 97 is rotatably attached via a bearing base 94 provided at the tip of the push rod 99. The push rod 99 is attached to the upper holding plate 31 via a support pin (not shown) provided near the tip, and the push rod 99 is rotatable about the support pin. A gear 90 that meshes with a gear 88 attached to the electric roller 95 is attached to one end of the center shaft of the presser roller 97.

  Similar to the wire gripping tool 23 of the first embodiment, when the handle 25 and the push rod 99 are gripped so that the end of the wire 21 protrudes from the through hole 75 of the central shaft 37 so as to approach each other, the push rod 99 The wire 21 is sandwiched between a presser roller 97 and an electric roller 95 provided at the tip of the wire. At the same time, the gears 88 and 90 mesh with each other. When the electric motor 91 is driven in this state, the electric roller 95 is rotated through the worm 92 and the worm wheel 93, and the presser roller 97 is further rotated through the gears 88 and 90. The wire 21 is pulled upward by the rotation of the two rollers, and the wire 21 is not loosened. As described above, in the oyster tying tool 2 of the second embodiment, since the electric wire gripping tool 87 is adopted, the wire 21 can be loosened very easily.

  By using the oyster lashing tools 1 and 2 as described above, the oyster can be easily lashed. Since the hand tool 17 can be rotated in one direction by rotating the manual lever 3, the operability is very good. Usually, a large force is required to lock the wire 21 with the sword tool 17, but with the oyster lashing tools 1 and 2, the gear ratio between the lever gear 5 and the body gear 7 is set appropriately, Since the length of the manual lever 3 is increased, a large force is not required. Further, when the wire 21 is tied up with the tool 17 and the wire 21 is loosened and there is a large gap between the wire 21 and the Munetake bamboo 19, the wire 21 cannot be tightly bound. Since 1 and 2 are provided with the wire gripping tools 23 and 87, the looseness of the wire 21 can be easily removed and the wire 21 can be firmly bound.

  In the above embodiment, the lever gear 5 is driven by the manual lever 3, but instead of the manual lever 3, the lever gear 5 may be rotationally driven by an electric motor. As a result, the wire 21 can be easily secured. Moreover, in the said embodiment, although the oyster lashing tools 1 and 2 which tie up the oyster using the Miso bamboo 19 were shown, the lashing tool which concerns on this invention is used for lashing of cocoons other than the said oyster. It goes without saying that can also be used. For example, when manufacturing a shark for fishing pearls, a shark used for fishing, etc., the lashing tool can be easily and quickly advanced by using the lashing tool according to the present invention. The material of the cocoons is not limited to the sushi bamboo, but may be other bamboos or even wood.
