Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to a squid fishing hook.

(Prior art and problems to be solved by the invention) In general, squid fishing hooks have a concave part _a2 formed at the bottom of the lure body A, as shown _in FIG. A slide tube B is installed inside through the slide tube B, and the slide tube B and the bait A are sandwiched between the stop ring 1 and the core body 4 to which the needle body 2 at the lower end of the connecting rod 3 is attached. It was devised so that it could be disassembled by removing the upper retaining ring 1 from the connecting rod 3 while keeping the body A pushed downward.

However, not only during disassembly but also when assembling, there is a restriction that one hand is required to hold the lure A downward while the other hand is used to remove and attach the retaining ring 1, which reduces work efficiency. In a very bad situation, there was a risk that the stop ring 1 would fall and be lost by mistake when replacing the lure A on board the ship, which requires particularly quick work.

The problem to be solved by this invention is to provide a fishhook that can simplify disassembly and assembly operations and prevent parts from falling and being lost during disassembly and assembly.

(Means for solving the problem) The technical means taken to solve the above problem is to provide a recess that communicates with the internal hole at the upper or lower end of the lure, and to install an elastic spring in the recess. A slide tube is installed inside through the slide tube, and a connecting rod for connecting a stop ring passing through an internal through hole is passed through the slide tube to connect the slide tube and bait to the stop ring and the needle at the lower end of the connecting rod. A gradually increasing inclined surface is held between the core rod and the attached core rod, and is attached to the outer end of the slide tube to fit and lock onto the inner surface of the recess when the slide tube enters the recess against the elastic force of the repulsive force. The purpose is to form the inner hole in a flat shape that rotates as the connecting rod rotates.

(Function) The effect of the technical means taken by the present invention is to move the slide tube into the recess formed at the upper or lower end of the bait object against the internal elastic force, and to gradually increase the slope of the outer end of the slide tube. is fitted and locked into the inner surface of the recess to cause the upper end of the connecting rod to protrude from the slide tube or bait lure.

(Example) The lure A is formed using a material such as hard synthetic resin or lead, and has an inner part for the connecting rod 3 that connects the stop ring 1 and the core rod 4 to which the needle body 2 is attached. A recess a that is of a well-known form and has a through hole _a1 , and has a slide tube B that passes through the connecting rod 3 and a resilient spring C that urges the slide tube B outward at the upper or lower end thereof. ₂ will be provided.

The recessed portion _A2 is formed to have a desired depth while communicating with the internal through hole _A1 , and is always urged outward by an elastic spring C inside and the spring C. Install slide tube B inside.

The slide tube B is made of a desired material such as synthetic resin or metal, and is formed with both ends open so that the connecting rod 3 passing through the internal through hole _A1 passes therethrough, and has a recessed portion at the outer end. a ₂ A flat hole b ₃ that forms a gradually increasing slope b ₁ that fits and locks on the inner surface, and partially or entirely rotates with the rotation of the connecting rod 3 in the inner hole b ₂
shall be.

The gradually increasing slope _b1 engages the slide cylinder B, which enters against the elastic force of the elastic spring C, with the inner surface of the recess _a2 during disassembly or assembly as shown in Figs. 5 and 6. It has the function of stopping the connecting rod 3 from protruding outward, and has a cross-shaped portion as shown in Fig. 8, which has a tapered surface so that the diameter gradually increases as shown in Fig. 2. The slide cylinder B is formed by a forming means such as having a wedge-shaped protrusion 5 protruding from a radial portion or by forming the slide cylinder B into a soft tube shape as shown in FIG. 9 and crushing it into a flat shape.

The flat hole _b3 is designed to transmit the rotational force of the stop ring 1 to the slide cylinder B after assembly, thereby releasing the engagement relationship with the inner surface of the recess part _a2 and restoring the slide cylinder B to its original position. Form in hole b ₂ .

When assembling and forming the squid fishing hook of the present invention, the slide tube B is fitted and locked into the inner surface of the recess _A2 by advancing against the repulsive force of the repulsive spring C, and the connecting rod 3 is assembled. Make the upper end protrude outward. Next, connect the connecting rod 3 equipped with the core rod 4 with the needle body 2 at the lower end through the internal through hole a ₁
and insert it through the inner hole _b2 . After that, the stop ring 1 is connected to the connecting rod 3, and the stop ring 1 is rotated to release the engagement relationship with the inner surface of the recess a ₂ of the slide tube B, thereby returning the slide tube B to its original state. Restore it to complete the assembly (Figure 5). On the other hand, when disassembling it, the assembly process can be performed in reverse (Fig. 6).

(Effects of the invention) Since the present invention is constructed as described above, it has the following advantages.

Since it is not necessary to keep the lure depressed with one hand, the stop ring can be attached and removed with both hands, and disassembly and assembly operations are extremely easy. Therefore, in the event that the fishing lines to which the artificial bait hooks are attached become entangled with each other in the field, disassembly and assembly can be carried out quickly when it is desired to replace the artificial bait itself with one of a different color.

Since disassembly and assembly can be performed with both hands, the risk of losing not only the stop ring but also the slide tube is reduced as much as possible.

Thus, the intended purpose can be achieved.
