AI Technical Summary

Technical Problem

The existing sub-wires are easily damaged at the knot, affecting the tensile strength and making them prone to breakage.

Method used

The protective rope, with its hollow structure, connects to the main line via a figure-eight loop in an arc-shaped design to prevent the sub-line from tangling. Combined with the design of annular grooves and threaded grooves, it facilitates quick breaking of the protective rope and insertion of sub-lines.

Benefits of technology

Protects the integrity of the sub-line, prevents damage, maintains tensile strength, and is simple and quick to operate.

Abstract

This invention discloses a knot-free and damage-free leader fishing line, belonging to the field of fishing tackle technology. It includes a line body comprising a main line and a leader. A protective line rope is detachably connected to the end of the leader away from the hook. The protective line rope has a hollow structure with an internal cavity. The inner diameter of the cavity is larger than the diameter of the leader. The leader slides into the cavity and passes through the protective line rope. This invention, by setting a protective line rope on the outside of the leader and utilizing the arc-shaped rope's connection to the figure-eight loop of the main line, eliminates the need for knotting the leader, protecting its integrity and preventing damage from knots, thus protecting the leader's tensile strength.
