Technical Field
[0001] This utility model relates to the field of welding devices, and in particular to a novel telescopic hook shank mackerel hook. Background Technology
[0002] Spanish mackerel is highly favored by consumers for its delicious and nutritious meat, and it is an important fishing and aquaculture target in coastal areas of China. Spanish mackerel is mainly caught using fishing gear such as trawls, purse seines, and gillnets. Due to its strong migratory nature, the fishing season is mainly concentrated in spring and autumn. In recent years, with the increase in market demand, the Spanish mackerel aquaculture industry has also gradually developed.
[0003] However, existing fishhooks still have some shortcomings and areas for improvement in practical use. Short hook shanks are prone to line breakage and fish escape. After the line breaks, the hook remains in the fish's mouth, making it difficult for the fish to survive and resulting in unnecessary waste of resources. If the hook shank is lengthened, the exposed part is too long, making the fish wary and unwilling to bite. If the hook shank is shortened by inserting it deeper into the lure, the hook point will be at the tail of the bait. Since mackerel's feeding habit is to attack the head of the bait fish, the hook will remain outside the fish's mouth and cannot be pierced. Therefore, those skilled in the art provide a new type of telescopic hook shank mackerel hook to solve the problems mentioned in the background art. Utility Model Content
