Description

A lead sinker without bottom hanging

技术领域Technical Field

The utility model relates to the technical field related to lead sinkers, in particular to a lead sinker without a bottom hanging.

Background technique

Fishing is something that many fishing enthusiasts are addicted to, especially fishing in the wild. From the seaside and riverside to the lakeside and streamside, fishing enthusiasts can be seen everywhere. However, the most troublesome thing for anglers is that they are unfamiliar with the water environment when fishing in the wild. There are often stones, sand, and water plants at the bottom of the water. Fishes often prefer to live in places with many underwater stones, branches, roots, and water plants. Therefore, even if anglers know that there are these obstacles underwater, they are willing to fish in these places and make them their first choice of hook positions.

The use of lead sinkers is essential in fishing. When casting a long distance, anglers use their weight to quickly and accurately move the fishhook and bait to the target position. After entering the water, their weight can help balance the fishing group to prevent the fishing group from being washed away by the current. However, existing lead sinkers are easily stuck in underwater debris such as tree roots, water plants or underwater garbage, especially in the gaps between stones, which makes it almost impossible to recover the fish and the entire fishing group. This is also the most distressing thing for anglers and greatly reduces the fun of fishing.

The Chinese patent publication number is CN211746352U, and the authorization announcement date is October 27, 2020. It discloses a fishing gear with an anti-bottom hanging lead sinker, including a fishing rod, a first winding reel, a second winding reel, a first fishing rod line, a second fishing rod line, a first connecting ring, a second connecting ring, a third connecting ring, a lead sinker, a lead sinker hook, a fish hook line, a fish hook and a bait cavity; the first fishing rod line is connected to the first connecting ring, the lead sinker, and the second connecting ring in sequence; one end of the fish hook line is connected to the second connecting ring, and the other end is connected to the fish hook or the bait cavity; the second fishing rod line is connected to the second connecting ring and the lead sinker hook in sequence.

In the above patent, the lead sinker hook is set on the bottom surface of the lead sinker. When the lead sinker may get stuck on the bottom, the first fishing rod line and the second fishing rod line are set to change the force direction of the lead sinker to make the lead sinker escape from the bottom-hanging dilemma. This method is simple, but when encountering complex debris such as tree branches, the lead sinker is still difficult to recover, resulting in the loss of the lead sinker and the fishing gear, and also causing damage and pollution to the water environment; and if a plastic shell is used to protect the fish hook and the lead sinker to prevent it from getting stuck on the bottom, it is easy to be damaged and easily washed away by water when encountering fast water flow, and the positioning effect is poor.
