  • Patent number: 8365461
    Abstract: Provided is a long line fishing that prevents a tubular sleeve from separating from the external circumference of a main line no matter how large force may be radially applied from the outside, reduces friction, and makes it possible to quickly and easily connecting a string to a simple connection hook of a swivel. The present invention may be implemented by fitting a plurality of tubular sleeve on a long main line at predetermined positions, disposing clover stoppers at both sides of the tubular sleeves at predetermined positions to prevent the tubular sleeve s from longitudinally moving, and protruding hook from the external circumference by striking the external circumference of the tubular sleeve with a punch through a hole.

  • Publication number: 20070031183
    Abstract: The present invention relates to a ball bearing swivel connector for realizing a maximum tensile strength and relative rotation efficiency by using a minimum number of constituent elements at a minimum cost, preventing a fishing line from being tangled, and facilitating simpler manufacturing and assembly processes The ball bearing swivel connector includes an upper pin and a lower pin respectively extending to upper and lower ends of a body and having respective connecting rings penetrating therethrough, and a plurality of ball bearings for supporting the two pins in the body so that the two pins may relatively rotate. A race is formed at one end of the body extended as a small diameter tube bearing to support the plurality of ball bearings, and the other end of the body where the upper pin is inserted is formed to correspond to a shoulder of the upper pin in a drawing process so that the two pins in the body may be rotatably formed.
