Description

[Detailed description of the invention] This invention relates to a device used to make anti-float rubber (referred to as a stopper).

When attaching a float to a fishing line, stoppers 10 are used before and after the float 21 to fix it, but this stopper is usually a piece of rubber with a piece of piano wire 11' folded in half and stuck there. (See Figure 1).

To attach this commercialized stopper to the thread 20 as shown in Figure 2, insert the thread 20 into a loop made by bending piano wire, etc., and then insert the piano wire 11' on the other side. It brings it out.

(See Figure 2) By the way, in order to prevent the attached stopper from moving freely, the material of the rubber piece must be highly elastic and the friction between the thread and the rubber piece is large, such as urethane rubber. Something is good.

However, when commercializing it, it is necessary to fold the piano wire in half, hook the folded part onto a needle, and then pierce the needle into the rubber, so urethane rubber has the drawback that it is difficult to penetrate the wire, making it difficult to commercialize it. .

Therefore, the present invention was devised so that even materials that are difficult to penetrate with a needle, such as urethane rubber, can be penetrated extremely easily.

The present invention consists of a fixed body 3, a fitting body 2, and an operating barrel 1.

A floating rubber fixing body having a needle through hole 3b formed in the axial direction and a rubber mounting hole 3a coaxially communicating with the through hole in the head part is fitted into the head of the fixing body. A hollow portion 2b is provided, and a needle guide hole 2 is provided in communication with the hollow portion in the axial direction.
This floating stopper manufacturing tool consists of a fitting body 2 provided with a hole 1a, and an operating tube fitted into the fitting body 2 so as to be slidable in the axial direction and having an air hole 1a provided in the head.

Next, to further explain based on the illustrated embodiment, the fixed body 3 is a cylindrical body, and a convex portion is integrally provided on the head thereof, and the needle through hole 3b and the convex portion 3A are formed along the axis of the cylindrical body. A rubber mounting hole 3a is provided coaxially and communicating with each other.

Further, the fitting body 2 is a cylindrical body, and its head is provided with a concave hollow portion that fits into the convex portion of the fixed body 3, and is passed through the needle guide hole 2a along the axis.

The operation tube 1 is a hollow cylinder having an inner diameter slightly larger than the outer diameter of the two cylindrical bodies, and has a closed head and an air hole 1a.

The air hole 1a functions as an air discharge hole of the operation barrel 1.

Next, how to use it will be explained. First, urethane rubber is attached to the rubber attachment hole 3a, and the fitting body 2 is placed over the fitting body 2 so that the concave hollow body 2b is aligned with the convex portion 3A of the fixed body.

Thereafter, the needle 4 is stuck through the guide hole 2a of the fitting body 2, and the operation barrel 1 is placed over the needle and pushed.

At this time, the air in the operation tube 1 is discharged to the outside from the air hole 1a, and the needle is pressed smoothly.

Then, the needle pierces the urethane rubber along the central axis.

Next, take out the urethane rubber with the needle stuck in it,
Just hang it on the hook 4a at the head of 20 needles and pull it out with pliers or the like.

Since the present invention is configured as described above, it produces the following unique effects.

First, since the anti-floating rubber is fixed and the needle is guided in the axial direction from above, even if it is highly elastic and small like urethane rubber, the needle will be reliably aligned with the axis of the anti-floating rubber. It penetrates along the line and does not deviate.

In addition, since the operating barrel 1 is placed over the fitting body 2 and is slid in the axial direction to push the needle, a force is constantly exerted to push the needle in the axial direction, and no force is applied in other directions.

Therefore, there is less risk of the needle breaking.

Even if the needle should break, it is safe because it will happen inside the operation tube.

As described above, the present invention is an extremely practical invention.
