AI Technical Summary
Existing fishing sinkers are prone to snagging in swift currents, leading to the loss of the fishing rig, which affects the fishing experience and increases economic losses. In addition, existing anti-snagging devices are complex in structure or not easy to detach quickly.
A sinker detachment and anti-snagging device was designed, comprising a sleeve, a first connecting rod, a compression spring, and a second connecting rod. The compression spring separates the sinker from the connecting rod, and the ball head and ball head seat form an angle to prevent the fishing rig from tangling and achieve rapid separation.
The simplified device structure improves stability and success rate in complex waters, reduces the frequency of snagging the sinker, lowers the risk of losing the fishing rig, and enhances the fishing experience.

TECHNICAL FIELD
[0001] The utility model mainly relates to fishing equipment technical field, concretely is a fishing sinker separation anti -hanging bottom device for fishing. BACKGROUND
[0002] When fishing in natural water areas such as large rivers, large rivers and oceans, the water flow condition has a significant influence on the selection of fishing equipment. Generally, the more turbulent the water flow, the heavier the sinker that needs to be used to ensure that the bait can be stabilized at the predetermined position. However, the use of a heavier sinker can cause a series of problems. When the angler successfully catches a fish, the fish will instinctively flee to an area with more obstacles, at which time the sinker is easily stuck in the crevices of the reef or trapped in the water bottom debris, resulting in frequent occurrence of the bottom hanging phenomenon.
[0003] Once the bottom hanging occurs, not only will the fish escape, but more seriously, the entire fishing group may be lost due to the sinker's bottom hanging. Especially when fishing for large fish, since large fish have a strong fleeing force, they are more likely to drag the sinker into the obstacle area, greatly increasing the probability of sinker bottom hanging. This situation not only causes economic losses to the angler, but also greatly affects the fishing experience and reduces the enjoyment of fishing activities.
[0004] Currently, although there are some devices on the market that prevent the sinker from hanging on the bottom, most of them have complex structures and are inconvenient to operate. Moreover, in actual use, some devices cannot quickly and effectively separate the sinker from the fishing group when the sinker is hanging on the bottom, resulting in the risk of the fishing group still being difficult to avoid loss. To solve the above problems, the present application provides a sinker separation anti -hanging bottom device for fishing. CONTENT OF THE UTILITY MODEL
[0005] To achieve the above purpose, the utility model realizes the following technical scheme:
[0006] A sinker separation anti -hanging bottom device for fishing, comprising a sleeve, a sinker, a first connecting rod, a compression spring, a second connecting rod and a sleeve ring.
[0007] The first connecting ring is fixedly arranged at one end of the sleeve, and the other end is threadedly connected with a cover. The first connecting rod passes through the cover. A through hole is formed in the outer ring of the sleeve near the middle position. The sinker passes through the through hole. A stop ring is fixedly arranged on the inner wall of the sleeve near the through hole. A stop block is fixedly arranged on the outer ring of the first connecting rod. The stop block abuts against the stop ring. One end of the compression spring abuts against the stop block, and the other end abuts against the inner wall of the cover.
[0008] The first connecting rod end is fixedly provided with a ball head, the second connecting rod end is fixedly provided with a ball head seat, the ball head abuts against the inner wall of the ball head seat, a groove is formed in the outer ring of the second connecting rod near the sleeve ring position, a clamping ring is fixedly arranged in the inner ring of the sleeve ring, the clamping ring abuts against the groove, and a second connecting ring is fixedly arranged at the end of the sleeve ring.
[0009] Compared with the prior art, the utility model has the beneficial effects that:
[0010] 1、The utility model discloses simple structure, convenient to install and use, can stably work under various water environment, especially in the complex water bottom structure or the water area of more torrent, can effectively reduce the occurrence frequency of the fishing weight hanging bottom, improve the success rate and experience of angling.
[0011] 2、Through the compression spring structure between the first connecting rod and the fishing weight, when the first connecting rod is pulled by external force, the fishing weight separates from the first connecting rod quickly, the weight of the fishing weight is reduced, the probability of the fishing weight hanging bottom is reduced, the whole fishing group is avoided to lose together, and the economic loss of the fisher is reduced.
[0012] 3、The ball head and the ball head seat between the first connecting rod and the second connecting rod are designed to form a proper included angle, the fishing group subline is avoided to be wound on the sleeve, and the stability and convenience during use are further improved.
