Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tool for an oyster farmer to suspend an oyster on a oyster raft, for lifting the oyster on a ship or the like.

[0002]

[Prior art]

 When loading oysters suspended on an oyster raft into a ship, unravel the wires bound to the bamboo of the oyster raft one by one, make a loop with the wire, and use that loop on the hook of the ship's wrecker. I hung it up after hanging it up to some extent.

[0003]

[Problems to be solved by the device]

 In order to hang the wire with oysters on the hook of the tow truck, I made a loop part again with the wire that I unrolled, carried it to the hook, and hung it on the hook, so the weight of the oyster is large, It was a time-consuming and difficult task.

[0004]

[Means for Solving the Problems]

 This tool allows you to easily grab and remove a wire with oysters and remove it, and attach a wire, and attach a wire part to the tip of the wire so that it can be hooked on the hook of a tow truck.

[0005]

[Action]

 Instead of grasping the wire with oysters by hand, grasp it with this tool, and instead of releasing the wire bound to the bamboo of the oyster raft, if you cut the wire of that part with a clipper etc., you can also use the tool with the oyster It sank and the oysters were carried to the hook because the tip of the wire connected to this tool was previously hooked on the hook of the wrecker.

Embodiments will be described with reference to the drawings. In Fig. 4, grasp the grip 1 with your hand and apply the wire 4 with the oysters that hang on the oyster raft at a right angle to the wire 4 at the intersection of the frame 8 and the nail 3, and always press the spring The grip 1 which is being pushed in the direction of the wire 5 by means of 9 is pushed in the direction of the push bar 9, ie downward in this figure.

Then, the grip portion 1, the shaft 6, and the shaft 12 attached thereto move in the direction in which the pressing spring 9 exists, and the claw 3 that moves with the shaft 13 as a fulcrum moves the portion on which the wire 4 hits. open.

As a result, the wire 4 is pushed into the recesses 10 and 11 of the frame 8 as shown in FIGS. 5, 6 and 8, and when the hand holding the grip portion 1 is released, the push spring 9 is restored. By the force, it is sandwiched between the claw 3 and the frame 8 and fixed to the wire 4 with the oyster 15.

A wire 5 is connected to the grip portion 1 and, as shown in FIGS. 8 and 9, the tip of the wire 5 is hooked in advance on a hook 16 of a tow truck. When pulled up, the wire 4 with the oysters 15 is bent and lifted at the recess 10 of the frame 8.

At this time, as shown in FIG. 5, a force is applied to the grip portion 1, the shaft 6 and the shaft 12 in an upward direction by the wire 5, and the wire 4 is applied to the recess 11 of the frame 8. Therefore, a force is applied downward by the weight of the oysters 15, and the wire 4 is further tightened by the claw 3 and the recess 11 of the frame 8 about the shaft 13 as a fulcrum, and thus the wire 4 does not fall off.

Although the wire 4 is sandwiched between the claw 3 and the frame 8, an appropriate gap is provided between them so that the wire 4 is not cut by it.

FIGS. 8 and 9 show how the tool is used, and FIG. 8 shows the tool attached to the wire 4 with the oysters 15.

Further, FIG. 9 shows the upper part of the wire 4 which is bound to the bamboo 14 of the oyster raft, which is cut with a clipper or the like. The tool 17 holding the wire 4 in this way is the oyster 15 With the weight of, the wire 5 sunk into the sea to the depth where the wire 5 hung on the hook 16 of the wrecker is stretched.

That is, at this point, since the tip of the wire 5 is hooked on the hook 16 of the tow truck, the wire 4 with the oysters 15 has been carried to the hook 16 of the tow truck.

[0015]

[Effect of device]

 Since the present invention is configured as described above, the tool 17 can be easily set by pushing the grip portion 1, there is no need to grasp the wire 4 with the oyster 15 by hand, and Since this tool 17 is connected to the hook 16 by the wire 5, the wire 4 with the oyster 15 can be attached to the hook 16 of the wrecker simply by cutting the wire 4 bound to the bamboo 14 of the oyster raft. Since it has been carried to that point, there is no need to carry it manually.

[0016] Therefore, as in the past, if the wire bound to bamboo is unraveled with one hand, and the wire is used to make a loop part, then carry it by hand to the hook of the wrecker and hang it on the hook. Since a series of operations are not required, shipping can be done easily.

Further, since this tool can be used in almost the same manner for raising and lowering the depth of oysters in the sea, work efficiency is improved.

Claims (1)

[Scope of utility model registration request] 1. A shaft 12 to be towed is attached with a shaft 12, to which a pawl 3 which moves around a shaft 13 as a fulcrum is connected, and by a restoring force of a pushing spring 9, a frame 8 and a pawl 3 are connected. A tool for lifting an oyster wire having a structure in which the wire 4 can be grabbed, and when the shaft 6 is further lifted, the force of tightening the wire 4 with the frame 8 and the claw 3 is increased by the gravity of the oyster 15 that is lifted.
