AI Technical Summary
Existing sinkers used for catching soft-shelled turtles are prone to swaying due to water flow during retrieval, causing the hook to deviate from its original path and reducing the probability of being hooked.
By setting a flow guide notch or installing a spiral fan blade on the plumb bob body, the plumb bob is rotated instead of oscillating by the impact force of the water flow. The impact force of the water flow is converted into rotational power through the flow guide notch or spiral fan blade, reducing the oscillation amplitude.
The sinker should be kept in a straight path during retrieval to increase the probability of catching a fish.

TECHNICAL FIELD
[0001] The utility model relates to the technical field of lead sinkers, and particularly relates to a lead sinker for catching soft-shelled turtles. BACKGROUND
[0002] Soft-shelled turtle catching is an activity for catching soft-shelled turtles by using specific skills. The main method is to catch soft-shelled turtles when they surface to breathe. The angler needs to throw the soft-shelled turtle hook beyond the soft-shelled turtle, and then quickly retrieve the soft-shelled turtle hook to hook the soft-shelled turtle on the retrieval path, so as to achieve the purpose of catching the soft-shelled turtle.
[0003] Because the soft-shelled turtle hook is light in weight, a lead sinker is connected to the front line by a pin connector during use. The lead sinker can help control the speed of the fishing set during fishing, and can also make the fish hook maintain a relatively stable forward path when being thrown and be thrown farther.
[0004] Most of the lead sinkers used for soft-shelled turtle catching are bullet-shaped, and the circular ring for binding the front line is arranged at the round end of the lead sinker. This results in the round end of the lead sinker being impacted by the water flow during the rapid retrieval of the fishing line. Due to the interaction between the surface of the lead sinker and the water, including friction, water flow speed difference, and unevenness of the surface of the lead sinker, the round end of the lead sinker is prone to uneven stress, which further causes the lead sinker to swing during retrieval, and further causes the soft-shelled turtle hook to deviate from the original fishing line path, greatly reducing the hooking probability. SUMMARY
[0005] To solve the above problems, that is, the lead sinker used for soft-shelled turtle catching is prone to swinging during retrieval, the utility model provides a lead sinker for soft-shelled turtle catching, which comprises a lead sinker body, a connecting ring is arranged at the top end of the lead sinker body, a plurality of flow guide notches are uniformly arranged at the top end of the lead sinker body along the circumferential direction thereof, and the flow guide notches are arranged in the shape of spiral vanes.
[0006] The utility model also provides a lead sinker for soft-shelled turtle catching, which comprises a lead sinker body, a mounting column is coaxially arranged at the top end of the lead sinker body, a connecting ring is arranged at one end of the mounting column away from the lead sinker body, and three spiral vanes are mounted on the side surface of the mounting column and uniformly arranged along the circumferential direction of the mounting column.
[0007] The utility model discloses a beneficial effect is: through setting up the flow guide gap or installing spiral fan blade, can make the lead drop body in the process of being recycled under the action of water flow impact force and rotate, and then make the water flow impact force mostly be converted as the rotation of lead drop body, and is not the swing of lead drop body, greatly reduce the swing amplitude of lead drop body, make lead drop body when being recycled can keep on relatively straight recovery route.

[0014] The preferred embodiments of the utility model are described below with reference to the drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the utility model, and are not intended to limit the protection scope of the utility model.
[0015] Example 1
[0016] The utility model discloses a kind of lead drop for hitting soft-shelled turtle, including lead drop body 1, the top of lead drop body 1 is welded with circular connecting ring 11, connecting ring 11 is connected with front lead by pin connector, it needs to be explained, pin connector needs to select with flexible swivel, flexible swivel can realize the purpose of 360 degrees free rotation, i.e. It can guarantee the purpose of the free rotation of lead drop body 1 relative to front lead.
[0017] The top end of the lead plummet body 1 is uniformly provided with four flow guide notches 12 along the circumference thereof, the flow guide notches 12 are arranged in the shape of spiral vanes 21, that is, when the water flow impacts on the top end of the lead plummet body 1, the water flow can be contacted with the flow guide notches 12, and then the acting force of the water flow is directly applied to the flow guide notches 12, under the action of the four flow guide notches 12, the impact force of the water flow can push the lead plummet body 1 to rotate, and further, the impact force of the water flow is converted into the acting force for pushing the lead plummet body 1 to rotate, instead of pushing the lead plummet body 1 to swing, so that the swing range of the lead plummet body 1 can be greatly reduced, the recovery path of the lead plummet body 1 is relatively straight, and the fish catching probability is improved.
[0018] Embodiment 2
[0019] The utility model discloses still put forward a kind of beat soft-shelled turtle lead plummet, including lead plummet body 1, the top end of lead plummet body 1 is welded with cylindrical mounting column 2, mounting column 2 is coaxially arranged with lead plummet body 1, mounting column 2 is welded with circular connecting ring 11 away from the one end of lead plummet body 1, connecting ring 11 is connected with front wire through pin connector, it needs to be explained, pin connector needs to select with flexible swivel, flexible swivel can realize 360 degrees free rotation purpose, that is, it can guarantee that lead plummet body 1 relatively front wire free rotation purpose.
[0020] The side surface of mounting column 2 is welded with three spiral vanes 21, the three spiral vanes 21 are uniformly arranged along the circumference of mounting column 2, when water flow impacts on the top end of lead plummet body 1, it will first impact on spiral vane 21, contact with spiral vane 21, and then the acting force of water flow is applied to spiral vane 21, under the action of the three spiral vanes 21, the impact force of water flow can push lead plummet body 1 to rotate, and since spiral vane 21 face cancels most of the acting force of water flow, and the flow guiding effect of spiral vane 21, so that the acting force directly applied to the top end of lead plummet is relatively small, that is, most of the impact force of water flow is applied to spiral vane 21 and converted into the acting force for pushing spiral vane 21 to rotate, instead of pushing lead plummet body 1 to swing, so that the swing range of lead plummet body 1 can be greatly reduced, the recovery path of lead plummet body 1 is relatively straight, and the fish catching probability is improved.
[0021] In conclusion, the utility model can make lead plummet body 1 rotate under the action of water flow impact force in the process of being recovered, and then most of the impact force of water flow is converted into the acting force for pushing lead plummet body 1 to rotate, instead of pushing lead plummet body 1 to swing, so that the swing range of lead plummet body 1 is greatly reduced, and lead plummet body 1 can keep on relatively straight recovery route when being recovered.
