一般的釣竿，是以抽出形式或接續形式來將複數的竿 體連結成一支釣竿。來提供配合其用途具備有各種機能的 各種形式的釣竿。例如，釣香魚用的香魚竿或溪流竿等的 延伸竿，爲了要容易取得釣到的魚，需要具有能在釣魚操 作時儘快變更釣竿的長度的機能。A typical fishing rod is a combination of a plurality of scorpions into a fishing rod in a drawn or continuation form. To provide various types of fishing rods with various functions in accordance with their use. For example, in order to easily obtain the fish caught, it is necessary to have the function of changing the length of the fishing rod as soon as possible during the fishing operation.
例如’某種以往的香魚竿，是將其他的延伸竿連結在 主竿的竿根側端部。這種延伸竿，不管是在收容於主竿內 的狀態（收容狀態）、從主竿內抽出到手邊的狀態（延伸 狀態），都可連結固定於主竿。而且，可因應釣魚操作中 的狀況’將延伸竿伸縮來調整釣竿全體的長度來進行釣魚 (例如參照日本專利文獻1 )。 【專利文獻1】 曰本實用新案第3 02 2411號公報（第2圖、第3圖） 【發明內容】 (發明欲解決的課題） 如第6圖所示’上述的傳統的釣竿，在延伸狀態，爲 了使延伸竿1 01的前側端部嵌合於主竿〗00的竿根側端部 內周面’配置有稍小於主竿的內徑的管狀的嵌合構件1 〇2 一 4- (2) 1292697 。因此’在延伸狀態，延伸竿i 〇 1的周面與嵌合構件1 Ο 2 的落差部（△ X )會變得很大。該落差部，會導致髒東西 進入到主竿與插入竿之間，而且也有損外觀。 (用以解決課題的手段） 第1發明的釣竿，是依序連結筒狀體的複數竿體而成 的釣竿’是具備有··主竿、以及可自由出入於主竿內地連 結在主竿的竿根側，不管是收容於主竿內的收容狀態，或 是抽出於主竿的竿根側的延伸狀態，都可固定於上述主竿 的延伸竿。 主竿’是具有：作爲主體實施了前端較細的錐桿處理 的筒狀的主體部、以及是可裝卸地連結於主體部的竿根側 的管狀構件，主體部的內周面全體成爲越竿根側越小直徑 化的逆錐桿面的栓部。另一方面，延伸竿，是具有··形成 有在前側端部外周面形成爲較其他部分更大直徑的嵌合公 部，且出入於主竿內的插入部、以及連結於插入部的竿根 側的把手部。插入部的嵌合公部是可嵌裝於主竿的主體部 的軸方向中央附近的內周面及栓部的內周面。 該釣竿的延伸竿，不管是收容於主竿內的狀態（收容 狀態）、或是從主竿內抽出至手邊的狀態（延伸狀態）， 都可連結固定於主竿。在進行釣魚期間，可將延伸竿從主 竿抽出至手邊成爲延伸狀態，或者可將延伸竿壓入至主竿 內成爲收容狀態，可因應狀況來調整釣竿全體的長度來進 行釣魚。具體來說，在各狀況，主竿與延伸竿是以以下的 -5- (3) 1292697 方式連結固定。 首先，在收容狀態’從竿根側將延伸竿插入到主竿內 的話，由於主竿的前端較細的錐桿的關係，延伸竿的嵌合 公部會嵌裝於主竿的軸方向中央附近的內周面。另一方面 ，在延伸狀態，從主竿內將延伸竿抽出至竿根側的話，延 伸竿的前側端部會從主竿的竿根側到達栓部內，會嵌裝於 其內周面。在這種情況，栓部會位於主竿內而不會提供嵌 合面，會突出於主竿的竿根側提供嵌合面，相對的主竿與 延伸竿的落差部會變小。將栓部卸下的話延伸竿會容易從 主竿分離。而且，在長期使用產生磨耗的情況能夠容易交 換栓部，經過長時間也能維持嵌裝力。 這裡所謂的直徑沒有變化的部分，是在軸方向一定範 圍直徑沒有變化的部分，或直徑變化極小的部分。 第2發明的釣竿，是針對第1發明的釣竿，栓部，其 外周面是越朝竿根側越小直徑化的錐桿面。 是將位於主竿的竿根側的栓部的內外周面作成錐桿面 ，在外觀上也可盡量地讓主竿與延伸竿的落差變小。 桌3發明的釣竿’是針對第1或2發明的釣竿，又具 備有以抽出形式連結在主竿的前側的主上竿。該主上竿具 有可裝卸地安裝於前側端部且朝外徑方向伸出的凸緣構件 〇 在使延伸竿延伸於主竿的竿根側的狀態，要在抽出形 式將連結於主竿的前側的主上竿收容於主竿內的話，主上 竿可能會再從主竿達到延伸竿內。也就是說，主上竿會完 -6- (4) 1292697 全進入到主竿內，可能會很難取出。在這種釣竿，主上竿 的前側的凸緣構件會抵接於主竿的前側端面，可防止主上 竿進入到主竿內。 第4發明的釣竿，是針對第3發明的釣竿，主上竿具 有可自由裝卸地安裝於竿根側端部的底栓部，該底栓部會 封住主上竿的竿根側。For example, in some conventional squid squid, other extension ridges are connected to the root end side of the main raft. This extension 可 can be connected and fixed to the main raft regardless of the state (accommodating state) accommodated in the main raft and the state (extended state) drawn from the main raft to the hand. In addition, it is possible to perform fishing by adjusting the length of the entire fishing rod in accordance with the situation in the fishing operation. (For example, refer to Japanese Patent Document 1). [Patent Document 1] Japanese Patent Application No. 3 02 2411 (Fig. 2, Fig. 3) [Explanation] (The problem to be solved by the invention) As shown in Fig. 6, the above-mentioned conventional fishing rod is extended. In the state in which the front end portion of the extension 竿101 is fitted to the inner peripheral surface of the ridge root end portion of the main 竿00, a tubular fitting member 1 〇2 -4 (which is slightly smaller than the inner diameter of the main cymbal) is disposed. 2) 1292697. Therefore, in the extended state, the circumferential surface of the extension 竿i 〇 1 and the falling portion (ΔX) of the fitting member 1 Ο 2 become large. The drop portion causes dirt to enter between the main and the insertion, and also damages the appearance. (Means for Solving the Problem) The fishing rod according to the first aspect of the invention is a fishing rod which is connected to a plurality of carcasses of a cylindrical body in sequence, and is provided with a main body and is freely accessible to the main body. The root side of the crucible can be fixed to the extension of the main crucible regardless of whether it is accommodated in the main crucible or extended from the root side of the main crucible. The main body ′′ is a tubular main body portion that is subjected to a tapered rod end treatment as a main body, and a tubular member that is detachably coupled to the root portion side of the main body portion, and the entire inner peripheral surface of the main body portion becomes The smaller the diameter of the root, the smaller the diameter of the counter-cone face. On the other hand, the extension 竿 has an insertion portion in which the outer peripheral surface of the front end portion is formed to have a larger diameter than the other portion, and the insertion portion that enters and exits the main cymbal and the cymbal that is connected to the insertion portion The handle on the root side. The fitting male portion of the insertion portion is an inner circumferential surface that can be fitted in the vicinity of the center in the axial direction of the main body portion of the main jaw, and an inner circumferential surface of the plug portion. The extension of the fishing rod can be connected and fixed to the main raft regardless of whether it is accommodated in the main raft (in a state of being housed) or in a state of being pulled out from the main raft to the hand (extended state). During the fishing period, the extension 竿 can be taken out from the main raft to the hand to be extended, or the extension 竿 can be pushed into the main 成为 to be in a accommodating state, and the length of the entire fishing rod can be adjusted according to the situation to perform fishing. Specifically, in each case, the main 竿 and the extension 连结 are fixed by the following -5- (3) 1292697. First, when the extension 竿 is inserted into the main raft from the root side in the accommodating state, the fitting mortise of the extension 会 is fitted in the center of the main yoke in the axial direction due to the thin tapered rod at the front end of the main cymbal. Near the inner circumference. On the other hand, in the extended state, when the extension 竿 is pulled out from the main raft to the root side, the front end of the extension 到达 is reached from the root side of the main raft into the spigot, and is fitted to the inner circumferential surface. In this case, the plug portion will be located in the main jaw without providing a fitting surface, and the mating surface will be provided to protrude from the root side of the main jaw, and the falling portion of the opposing main jaw and the extension jaw will become smaller. If the plug is removed, it will be easily separated from the main jaw. Further, in the case where wear occurs for a long period of time, the plug portion can be easily exchanged, and the fitting force can be maintained over a long period of time. Here, the portion where the diameter does not change is a portion where the diameter does not change in the axial direction, or a portion where the diameter changes extremely. The fishing rod according to the second aspect of the invention is the fishing rod of the first aspect of the invention, wherein the outer peripheral surface of the fishing rod is a tapered surface that is smaller in diameter toward the root side. The inner and outer peripheral surfaces of the plug portion on the root side of the main jaw are formed into a tapered surface, and the difference in the appearance of the main jaw and the extension weir can be made as small as possible. The fishing rod of the invention of the table 3 is directed to the fishing rod of the first or second invention, and has a main upper cymbal attached to the front side of the main raft in a drawing manner. The main upper cymbal has a flange member that is detachably attached to the front end portion and protrudes in the outer diameter direction, and the extension 竿 extends to the root side of the main raft, and is to be connected to the main raft in the drawing form. If the main scorpion on the front side is contained in the main raft, the main scorpion may reach the extension 竿 from the main raft. In other words, the main captain will finish -6- (4) 1292697 all into the main squat, it may be difficult to take out. In this fishing rod, the flange member on the front side of the main upper jaw abuts against the front end surface of the main jaw, preventing the main upper jaw from entering the main jaw. The fishing rod according to the fourth aspect of the invention is directed to the fishing rod according to the third aspect of the invention, wherein the main upper casing has a bottom plug portion that is detachably attached to the end portion of the root side, and the bottom plug portion seals the root side of the main upper jaw.

[Embodiment] (First Embodiment) Hereinafter, a first embodiment of the present invention will be described with reference to the drawings, and a fishing rod according to a first embodiment of the present invention is used for fishing rods for fishing a fish, as shown in Fig. 1. As shown, it has a main 竿 1 ' and an extension 竿 2 that can be freely connected from the root side of the main raft 1 . On the front side of the main raft 1, the main 竿3 and the middle 竿4 are connected. These steroids are formed by baking a prepreg which immerses a synthetic resin in a reinforcing fiber such as carbon fiber. The corpus callosum of the anterior side of the main iliac crest 1 is connected in a so-called withdrawal form, and can be freely inserted and exited from the anterior humeral body into the iliac crest located on the iliac crest side. The outer peripheral surface of the root side end portion of the body on the front side can be fitted to the front inner peripheral surface of the body adjacent to the root side of the base to be fixed to each other. A line card stopper is disposed at the front end of the front fine cymbal (not shown) on the side of the foremost -7- (5) 1292697. Further, the main cymbal 1 and the extension 竿 2 located on the base of the crotch can be connected and fixed to each other, as will be described later, in the extended state and the accommodating state. (For the main cymbal 1) The main cymbal 1 is a cylindrical body that has been treated with a tapered rod that is smaller in diameter toward the front side. The inner peripheral surface in the vicinity of the center in the axial direction of the main cymbal 1 is provided with a portion where the inner diameter does not change in the axial direction (Fig. 3: reference X range). In other words, the main cymbal 1 is a cone-rod process in which the inner diameter gradually increases from the front side toward the crotch side. In some of them, the inner diameter will not change partially (X range). In the portion of the root side of the root that is continuous in the X range, in order to recombine the usual taper, a large tapered taper portion is formed. The portion X whose diameter has not changed is fitted to the front end portion of the extension 竿 2 to be described later in the accommodation state (see the third stiffness). As shown in Figure 2, in the main 竿! The side portion of the root of the file is detachably attached to the plug portion 5. A male thread portion is formed on the outer peripheral surface of the root side end of the main jaw 1, and the male thread portion is formed with a threaded groove. The plug portion 5 is a tubular member composed of a prepreg material (lightweight, using the same technique as the normal structure) or a hard synthetic resin similar to the structure constituting the cartridge body. The front side has an inner diameter which is a diameter which is a female thread portion which is encased in the root end portion of the main crucible 1 and which is screwed to the male thread portion of the main crucible 1. On the other hand, the inner peripheral surface of the root portion side of the plug portion 5 is continuous with the inner peripheral surface of the root end portion of the main jaw 1, and the front side has a portion where the diameter does not change, and the root side of the root portion is more toward the root side. Small diameter of the inverse cone winter (6) 1292697 rod part. In this embodiment, although an example is shown in which the portion where the diameter of the inner peripheral surface of the plug portion 5 is not changed is combined with the reverse tapered rod portion, only the reverse tapered rod surface may be left. The inner peripheral surface (reverse cone surface) of the root portion side of the plug portion 5 is fitted to the front end portion of the extending jaw 2 to be described later in the extended state (see Fig. 2). The outer peripheral surface of the plug portion 5 is preferably formed on the front end portion to match the outer peripheral surface of the main cymbal 1, and the reverse tapered shank surface which is gradually reduced in diameter to the root side is preferably formed. (For extension 竿 2) As shown in Figs. 1 to 3, the extension 竿 2 is an insertion portion 6 inserted from the root side of the main cymbal 1 into the inside thereof, and a root portion connected to the insertion portion 6 The handle portion 7 of the tubular member of the side having a large diameter is formed. The insertion portion 6 is a cylindrical body that can be inserted into the outer diameter of the main jaw 1 . The insertion portion 6 is a structure in which the taper does not change or a tapered rod which is made smaller toward the root side. The outer peripheral surface of the front end portion has a larger outer diameter than the other portions in a certain range in the axial direction, and is referred to as a fitting male portion 6a (see Figs. 2 and 3). The fitting male portion 6a is composed of a front side portion which is larger in diameter than the other portions and which has no change in diameter in the axial direction, and a reverse tapered rod portion which is smaller in diameter toward the root side than the root portion side. . The outer diameter of the portion of the fitting male portion 6a whose diameter does not change is a portion that is set to match the diameter of the main crucible 1, and the diameter of the counter-cone portion is the counter-cone portion of the conical portion 5. The inner diameter is set. The insertion portion 6 has a rubber case 8 -9 - (7) 1292697 disposed at the front end portion. The rubber outer casing 8 is a cylindrical member formed of a conventional elastic rubber and penetrating in the axial direction. The outer peripheral surface of the root side is a portion that has been cut off, and is inserted into the front end portion of the insertion portion 6 to be fixed by an adhesive. The inner diameter of the front side of the rubber casing 8 is a taper bar process in which the diameter is increased toward the front end portion. A "crack" is also formed in the axial direction from the end portion on the front side. The rubber casing 8 is a structure for smoothly guiding the main upper jaw 3 into the insertion portion 6 when the main upper jaw 3 connected to the front side of the main crucible 1 in the drawing form is housed in the main crucible 1 . On the other hand, the handle portion 7 is a tubular member having a larger diameter than the insertion portion 6 and a diameter matching the outer peripheral surface of the main rim 1. The fiber reinforced resin may be used in the same manner as the main rim 1 or the insertion portion 6, or may be composed of another metal material. In a state in which the insertion portion 6 is inserted from the front side, the handle portion 7 detachably attached to the insertion portion 6 is attached to the root end portion of the insertion portion 6. The handle portion 7 may be in a state in which the insertion portion 6 is completely inserted, or a state in which the insertion portion 6 is partially inserted into the front end portion of the handle portion 7^. Alternatively, the handle portion 7 may be fixed to the insertion portion 6 by adhesion. (For the main upper part 3) As shown in Fig. 4 and Fig. 5, the main upper jaw 3 is also a cylindrical body which is subjected to a tapered rod with a thin tip. As described above, it is connected to the front side of $ 竿1 by extraction. The mouth portion 1 is detachably attached to the front end portion of the main upper jaw 3, and the bottom plug portion 11 is detachably attached to the root end portion. -10- (8) 1292697
在主上竿3的前側端部外周面是成爲形成螺紋溝槽的 螺紋部分。口栓部1 〇是裝卸自如地螺合安裝在這裡。口 栓部1 〇 ’是由合成樹脂（例如彈性橡膠）或輕合金（鋁 等金屬）所構成而是在軸方向貫穿的中空的略管狀的構件 。中竿4等構件會插穿該口栓部10的中空部。口栓部10 ’在內周面具有螺合安裝於上述的主上竿3的螺母部分， 是以內包於主上竿3的前側端部的方式被安裝在主上竿3 。該口栓部1 0的外徑，是被設定成大於主竿i的前側端 部的內徑。也就是說，口栓部1 〇，在主上竿3的前側是 朝外方向伸出，來維持讓主上竿3不會進入到主竿1內的 情形。藉由安裝該口栓部1 0，例如在結束釣魚而要將釣 竿收起來時，不會不小心讓主上竿3深入到主竿1而產生 不便。The outer peripheral surface of the front end portion of the main upper cymbal 3 is a threaded portion which becomes a thread groove. The port plug 1 is slidably mounted here. The plug portion 1 〇 ' is a hollow, slightly tubular member that is formed of a synthetic resin (e.g., elastic rubber) or a light alloy (metal such as aluminum) but penetrates in the axial direction. A member such as the middle 4 is inserted through the hollow portion of the mouth portion 10. The port portion 10' has a nut portion screwed to the main upper jaw 3 on the inner peripheral surface, and is attached to the main upper jaw 3 so as to be wrapped around the front end portion of the main upper jaw 3. The outer diameter of the port plug portion 10 is set to be larger than the inner diameter of the front end portion of the main cymbal i. That is, the mouth plug portion 1 is extended outward in the front side of the main upper jaw 3 to maintain the main upper jaw 3 from entering the main jaw 1. By installing the port portion 10, for example, when the fishing rod is to be collected at the end of fishing, it is inconvenient that the main upper jaw 3 is not inadvertently penetrated into the main raft 1.
在主上竿3的竿根側端部內周面成爲直接形成螺紋溝 槽的螺母部分。在這裡是裝卸自如地螺合安裝著底栓部 1 1。底栓部1 1是由彈性橡膠或輕金屬所構成的栓部構件 。前側的外周面是成爲螺合安裝於主上竿3的竿根側端部 的螺紋部分，螺紋部分的竿根側是成爲配合主上竿3的外 徑的頭部分。底栓部1 1爲了輕量化也可以予以中空化， 也可形成貫穿於軸方向的空氣孔。在第5圖，是揭示了配 置有用來封閉底栓部1 1的前側的橡膠板的構造。該底栓 部11，其功能是作爲用來防止中竿4等插穿主上竿3朝 竿根側伸出來的栓部的功能。 -11 - (9) 1292697 (針對主竿1與延伸竿2的連結固定） 該釣竿的延伸竿2，不管是收容於主竿1內的狀態（ 收容狀態：第3圖）、或是從主竿1內抽出至手邊的狀態 (延伸狀態：第2圖），都可連結固定於主竿1。在進行 釣魚的期間，可調整成將延伸竿2從主竿1抽出至手邊的 延伸狀態，或是調整成將延伸竿2壓入至主竿1內的收容 狀態，可因應狀況來調整釣竿全體的長度來進行釣魚。 如第3圖所示，在收容狀態，如果從竿根側將延伸竿 2的插入部6插入到主竿1內的話，延伸竿2的插入部6 的嵌合公部6a的直徑沒有變化的部分，會嵌裝於主竿1 的軸方向中央附近所形成的直徑沒有變化的部分X。藉由 在收容狀態在主竿1的軸方向中央附近的內周面與延伸竿 嵌裝在一起，則不會搖晃且在使用中主竿不會落下。在嵌 裝面很難積存髒東西。 另一方面，如第2圖所示，在延伸狀態，如果從主竿 1內將延伸竿2抽出至竿根側的話，延伸竿2的前側端部 的嵌合公部6a會從主竿1的竿根側到達栓部5內，嵌合 公部6a的逆錐桿部分會嵌合安裝於栓部5的內周面（逆 錐桿部分）。在這種情況，栓部5位於主竿1內不會提供 嵌合面’突出於主竿〗的竿根側會提供嵌合面，相對的主 竿1與延伸竿2的插入部6的外周面的落差部會變小。栓 部5也作成越向竿根側越小直徑化的錐桿面，外觀上也較 不會看出落差。 如果將栓部5從主竿1卸下的話，延伸竿2就能容易 -12- (10) 1292697 k主竿1分離。如果由於長期使用而在栓部5產生磨耗時 ’只要將把手部7從插入部6卸下，將栓部5從插入部卸 下就目谷易父換’能長期維持嵌裝力。 (其他實施方式） (a)在上述栓部5的內周面（嵌合面），也可以貼 上由環氧樹脂所構成的薄膜。也能夠防止栓部5與嵌合公 部6 a在嵌裝時的相互的磨耗。 (b )由栓部5的竿根側端部起，在軸方向也可以因 應需要加入「裂紋部」。 (發明效果） 藉由本發明的釣竿，可以使主竿與延伸竿之間的釣竿 的長度變化，且可以解除主竿與延伸竿之間的較大的落差 〇 即使由於長期使用讓主竿與延伸竿的嵌合力降低，也 能容易地回復其嵌合力。 【圖式簡單說明】 第1圖是採用本發明的第一實施方式的釣竿的全體圖 〇 第2圖是示意性地顯示第1圖的主竿1與延伸竿2的 延伸狀態的圖面。 第3圖是不意性地顯示第1圖的主竿1與延伸竿2的 -13-The inner peripheral surface of the root end side of the main upper jaw 3 is a nut portion that directly forms a thread groove. Here, the bottom plug portion 1 1 is detachably attached to the bottom. The bottom plug portion 1 1 is a plug member composed of an elastic rubber or a light metal. The outer peripheral surface of the front side is a threaded portion that is screwed to the root end portion of the main upper jaw 3, and the root side of the threaded portion is a head portion that fits the outer diameter of the main upper jaw 3. The bottom plug portion 1 1 may be hollowed out for weight reduction, or an air hole may be formed through the axial direction. In Fig. 5, a configuration in which a rubber sheet for closing the front side of the bottom plug portion 1 1 is disposed is disclosed. The bottom plug portion 11 functions as a plug portion for preventing the middle jaw 4 or the like from being inserted through the main upper jaw 3 toward the root side. -11 - (9) 1292697 (fixed for the connection between the main raft 1 and the extension 竿 2) The extension 竿 2 of the fishing rod, whether it is housed in the main raft 1 (housing state: Fig. 3), or from the main The state in which the 竿1 is pulled out to the hand (extended state: Fig. 2) can be connected and fixed to the main 竿1. During fishing, it may be adjusted to extend the extension 竿 2 from the main raft 1 to the hand, or to adjust the extension 竿 2 into the accommodating state of the main raft 1, and adjust the overall fishing rod according to the situation. The length to go fishing. As shown in Fig. 3, in the accommodated state, if the insertion portion 6 of the extension 竿 2 is inserted into the main cymbal 1 from the root side, the diameter of the fitting male portion 6a of the insertion portion 6 of the extension 竿 2 does not change. In part, a portion X having a diameter which is not changed near the center of the main axis 1 in the axial direction is fitted. By being fitted to the extension 竿 in the accommodation state in the vicinity of the center of the main cymbal 1 in the axial direction, the main cymbal is not shaken and the main shovel does not fall during use. It is difficult to accumulate dirt on the embedded surface. On the other hand, as shown in Fig. 2, in the extended state, if the extension 竿 2 is pulled out from the main raft 1 to the root side, the fitting portion 6a of the front end portion of the extension 竿 2 will be from the main 竿 1 The root side of the hook reaches the plug portion 5, and the reverse taper portion of the fitting portion 6a is fitted and attached to the inner peripheral surface of the plug portion 5 (reverse taper portion). In this case, the plug portion 5 is located in the main jaw 1 and does not provide the fitting surface. The base side of the main protrusion 提供 provides a fitting surface, and the outer circumference of the opposite main ridge 1 and the insertion portion 6 of the extension 竿 2 The drop of the face will become smaller. The plug portion 5 is also formed as a tapered rod surface which is smaller in diameter toward the root side, and the drop is not seen in appearance. If the bolt portion 5 is detached from the main cymbal 1, the extension 竿 2 can be easily -12- (10) 1292697 k main 竿 1 separation. When the plug portion 5 is worn out due to long-term use, the handle portion 7 is detached from the insertion portion 6, and the plug portion 5 is removed from the insertion portion, so that the mounting force can be maintained for a long period of time. (Other embodiment) (a) On the inner peripheral surface (fitting surface) of the plug portion 5, a film made of an epoxy resin may be attached. It is also possible to prevent mutual wear of the plug portion 5 and the fitting portion 6a at the time of fitting. (b) From the root end side of the plug portion 5, a "crack portion" may be added in the axial direction as needed. (Effect of the Invention) With the fishing rod of the present invention, the length of the fishing rod between the main raft and the extension raft can be changed, and a large drop between the main raft and the extension raft can be released, even if the main raft and the extension are extended due to long-term use. The chimerism of the tendon is reduced, and the fitting force can be easily restored.
