DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage rod tube holding mechanism.

[0002]

2. Description of the Related Art In general, there is widely known a fishing rod in which a storage rod tube is housed in a former rod, and the storage rod tube is spouted for fishing during fishing.

[0003] In such a protruding rod, a butt plug having a fitting protrusion made of an elastic material at the inner end is provided at the base end of the original rod, and the base end of the tip rod stored in the fitting protrusion is provided. There is one in which the inner surface is fitted and held (Japanese Utility Model Application Laid-Open No. 52-5985).
issue).

In recent years, it has been possible to adjust the length of a fishing rod by swinging out a required number of front rods stored and held in a former rod according to the conditions of a fishing place, the state of fish, the manner of fishing, and the like. There are fishing rods that can be used.

[0005] However, the outer diameter of the fitting projection formed on such a tail plug is adjusted so that the inner surfaces of the proximal ends of the plurality of front rods accommodated in the original rod are retained. From the side to the inner end side, a small diameter is formed with a step corresponding to the inner diameter of the base end of the storage rod tube.

For this reason, when the tip of the storage rod tube whose inner surface at the base end is fitted and held by the fitting projection is gripped to move a fishing spot or transport a fishing rod, the fitting projection is used. There is a possibility that the portion and the inner surface of the base end of the storage rod tube may come off, the former rod may fall out, and the former rod or the buttocks attached to this base end may be damaged.

On the other hand, in order to solve the falling off of the former rod,
It is conceivable to increase the outer diameter of the fitting projection so that the fitting projection is in close contact with the inner circumference of the base end of the storage rod pipe. It is effective for such points, but when the storage rod tube is extended,
A large force is required to separate the base end of the storage rod tube from the fitting protrusion, and if it is forcibly removed, the rod tube or buttocks may be damaged. The diameter could not be increased. Further, the present invention is a drawing rod in which an auxiliary rod having a grip portion is provided so as to be able to advance and retreat with respect to the original rod, and a bottom plug is attached to a base end of the auxiliary rod. There is also a fishing rod in which a fitting projection made of an elastic material is formed to fit and hold an inner surface of a base end of a former rod stored in the rod.

However, in this type of fishing rod, if the entire outer periphery of the fitting projection of the butt plug is formed to have a large diameter in order to avoid the detachment of the butt plug from the base end of the original rod, the same reason as described above. This can cause damage to the original rod, auxiliary rod, and buttocks, and furthermore, it is not possible to release the fitting smoothly and quickly when switching from the contracted bear to the extended state, and there is a possibility that the fish being taken in may be released. there were.

On the other hand, if the fitting force of the fitting projection of the buttocks to the inner surface of the base end of the former rod is weakened, the stability of the auxiliary rod to the former rod in the contracted state of the rod is lacking, and the transport of the fishing rod is difficult. In such cases, the problem of the auxiliary rod falling off the former rod still remains.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems.
An object of the present invention is to provide a holding mechanism for a storage rod tube capable of effectively having an opposing function such as detachability.
