Description

Technical Field

[0001] This utility model belongs to the field of fishing gear technology, specifically relating to a retractable, damage-free protection fishing line leader. Background Technology

[0002] Fishing gear is a general term for various tools used directly for catching and harvesting economically valuable animals in waters. It typically consists of fishhooks, bait, and fishing lines, and some may also be equipped with floats, sinkers, or other accessories. Fishing lines include the main line and the leader line. The main line is used to connect the fishing rod, and the leader line is used to connect the fishhook and the main line.

[0003] Current leader lines all have a knotted section to prevent damage at the connection point between the leader line and the main line. However, when the leader line is knotted, it becomes incomplete, resulting in damage at the knot and affecting its tensile strength. The knotted area is prone to breakage under high tension. In patent application number 2025217367172, entitled "A Knot-Free and Damage-Free Leader Line Fishing Line," the inventor proposed a knot-free leader line that uses a protective cord to avoid damage to the leader line's tensile strength caused by knots. However, the protective cord does not completely protect the leader line, leaving a portion exposed. Therefore, to overcome this deficiency, a retractable and adjustable, damage-free protective leader line is needed. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a retractable and adjustable non-damaging fishing line leader that anglers can adjust to fully or partially cover a single leader according to their needs, thus solving the technical problems mentioned in the background.

[0005] The purpose of this invention is achieved as follows: A retractable, damage-free protective fishing line leader includes a single leader body. The single leader body is surrounded by a layer of lines, including an inner layer (2, 3, 4, 5, or 6 layers) and an outer layer (5, 6, 7, 8, 9, 10, 11, or 12 layers). The outer layer is positioned centrally within the inner layer, and the wound layers form a convex shape. By using this layer, if full coverage of the entire leader is required, the angler can push the 7th or 8th outer layer to the sides, effectively flattening the convex shape. This elongates the layer, achieving full coverage of the leader. If only a portion of the leader needs protection, the layers are pushed towards the center, creating a convex shape. Anglers can adjust the protective section themselves, and it protects the leader line without damaging the individual leader line.

[0006] Furthermore, the line layer can be made of braided thread, which can be made of cotton, silk, polyester, nylon, etc. By using braided thread for the line layer, this structure gives the line higher strength and durability. When subjected to external force, the braided thread can better distribute the force, reducing the risk of breakage. This is crucial for fishing activities, as fishing often requires withstanding the struggle of fish, especially when catching large fish. The high strength of the braided thread can effectively prevent line breakage and improve the success rate of the catch.

[0007] Furthermore, the single sub-line is connected to the main line, and the main line is connected to the fishing rod. The fishing rod is a telescopic rod with a grip at the butt end, and the grip is covered with a soft rubber layer. One end of the main line is equipped with a swivel, and the main line itself includes a rubber line stop, a line indicator, a cushioning pad, and a float.

[0008] Furthermore, a protective cord is provided on the outside of each individual sub-line. The protective cord is used in conjunction with the line layer. The protective cord can be used in conjunction with the line layer, or the line layer can be used alone instead of the protective cord. In other words, the sub-line with the protective cord structure of the previous patent could be used alone, and the sub-line with the line layer of this application can also be used alone, or the protective cord can be used in conjunction with the line layer.

[0009] The beneficial effects of this invention are as follows: By setting a layer of lines on the outside of a single leader line, when full coverage of the entire leader line is required, the angler can push the 7 or 8 layers of the outer layer to both sides, in other words, flatten the "convex" structure of the layer. At this time, the layer extends, achieving full coverage of the single leader line. If only a portion of the single leader line needs protection, the layer is pushed towards the center, forming a "convex" structure. The angler can adjust the protective section by themselves, protecting the leader line without damaging the individual leader line. Attached Figure Description

[0013] like Figure 2 As shown in the figure, this embodiment discloses a retractable, damage-free protective fishing line leader, including a single leader body 1. The single leader body 1 is externally wound with a line layer, which includes an inner line layer 2 (2, 3, 4, 5, or 6 layers). An outer line layer 3 is externally wound around the inner line layer, which has 5, 6, 7, 8, 9, 10, 11, or 12 layers. The outer line layer 3 is positioned centrally within the inner line layer 2, and the wound line layer has a convex shape. By setting a line layer on the outside of the single leader body 1, when full coverage protection of the entire single leader body 1 is required, the angler can push the 7th or 8th layer of the outer line layer 3 to both sides, in other words, flatten the convex shape of the line layer. At this time, the line layer extends, achieving full coverage protection of the single leader body 1. If only a portion of the single leader line 1 is protected, the line layers are pushed together towards the center, forming a convex structure. The angler can adjust the protected section themselves, ensuring that the single leader line 1 is protected without damage. Example

[0014] like Figure 1 and 2 As shown in the figure, this embodiment discloses a retractable, damage-free protective fishing line leader, including a single leader body 1.
