Description

Technical Field

[0001] This utility model relates to a knob-type fishing line knotter, belonging to the field of fishing gear technology. Background Technology

[0002] As people's living standards improve, fishing has gradually become a popular outdoor activity. Lure fishing, a relatively new fishing method, is gaining popularity among fishing enthusiasts in China. One of the main reasons is that lure fishing is often referred to as "water golf," an elegant sport that prioritizes environmental protection and optimizes the natural environment. Lure fishing, also known as artificial bait fishing, is a method that mimics small creatures to provoke larger fish. Throughout the fishing process, the angler engages in full-body exercise, a significant difference from traditional fishing methods. Furthermore, lure fishing is environmentally friendly, pollution-free, requires no baiting, does not pollute the water, and is easy to carry. Compared to platform fishing, it eliminates the hassle of carrying large bags, tying hooks, and adjusting floats, and also avoids the concerns of preserving and carrying live bait.

[0003] In lure fishing, a leader needs to be tied to the front end of the PE mainline by tying a GT knot. Currently, it is common to tie the knot by hand. However, for fishing novices, tying a GT knot to connect the mainline and the leader is a rather troublesome task. Not only is the knotting work inefficient and difficult to operate, but the line winding effect is also poor and it is easy for the line to loosen.

[0004] There are currently three main types of knotters sold in the domestic market for tying front conductors and PE main lines. All three types are designed and imported from Japan. Through repeated comparison and analysis, each of these three types of products has different defects and shortcomings. For example, the first type of manual knotter has an unreasonable weight, is not portable, has a limited range of applicable PE wire sizes, is troublesome to thread, has a high PE wire loss, is difficult to pull out during use, and produces loose knots, while also consuming a lot of time. The second type of manual knotter uses a plastic bow-shaped structure, is easily damaged, is too large, not portable, time-consuming to operate, and consumes a lot of wire. The third type of electric knotter is large, not easy to carry, has a strong plastic feel, low strength, is motor-driven, not waterproof, consumes batteries, and produces loose knots.
