[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0025] Embodiment 1:

[0026] As Figures 1-5 shown, a seedling fishing device for crayfish farming includes a ground cage net body 1 and a ground cage skeleton 7 arranged inside the ground cage net body 1. A plurality of side inlets 2 are opened on the side of the ground cage net body 1. One end of the ground cage net body 1 is provided with a counterweight 4 through a first pull rope 3. The other end of the ground cage net body 1 is provided with an H-shaped floating block 6 through a second pull rope 5. The second pull rope 5 is wound around the outer surface of the H-shaped floating block 6. A third pull rope 14 is arranged on the outer surface of the H-shaped floating block 6. A card slot 8 for clamping the second pull rope 5 is opened on one side of the H-shaped floating block 6. An anti-loosening and anti-dropping component for preventing the second pull rope 5 from loosening and dropping is arranged in the card slot 8. When in use, the user lowers the ground cage into the water, and then ties one end of the third pull rope 14 to a tree branch or inserts a tree branch into the ground to achieve the fixing effect of the ground cage. At the same time, when in use, the user can release the second pull rope 5 wound around the outside of the H-shaped floating block 6 to facilitate adjusting the distance of the ground cage thrown into the water. By setting the H-shaped floating block 6, when the fixed end of the third pull rope 14 loosens and drops or the third pull rope 14 slips out of the user's hand during the process of throwing the ground cage, it floats on the water surface under the action of the H-shaped floating block 6, which is convenient for the user to fish for the ground cage, effectively avoiding the ground cage and the third pull rope 14 from sinking to the bottom of the water and making it inconvenient for the staff to fish.

[0027] Further, the anti-loosening component includes a C-shaped external thread cylinder 11 and a C-shaped internal thread cylinder 10 fixedly arranged inside the card slot 8. The C-shaped external thread cylinder 11 is threadedly connected to the C-shaped internal thread cylinder 10. At both ends of the outer surface of the C-shaped external thread cylinder 11, stop blocks 9 are fixedly arranged. At both ends of the inner wall of the C-shaped external thread cylinder 11, clamping blocks 12 for clamping the second pulling rope 5 are fixedly arranged. During use, when it is necessary to release or wind up the second pulling rope 5 to adjust the length, the user rotates the C-shaped external thread cylinder 11 so that one of the stop blocks 9 abuts against the end of the C-shaped internal thread cylinder 10. At this time, the opening sides of the C-shaped external thread cylinder 11 and the C-shaped internal thread cylinder 10 are aligned. Then, the second pulling rope 5 can be pulled outwards, and then the second pulling rope 5 is wound up or released. After the adjustment is completed, the second pulling rope 5 is inserted into the clamping block 12 again, and then the C-shaped external thread cylinder 11 is rotated in the reverse direction so that the other stop block 9 abuts against the end of the C-shaped internal thread cylinder 10. At this time, the opening side of the C-shaped internal thread cylinder 10 is closed by the C-shaped external thread cylinder 11, and the second pulling rope 5 is looped between the C-shaped internal thread cylinder 10 and the C-shaped external thread cylinder 11, effectively preventing the second pulling rope 5 from loosening and falling off under the action of external force.

[0028] Further, a plurality of counterweight weights are evenly arranged on both sides of the lower end of the cage net body 1, effectively ensuring that the cage is thrown into the water surface and sinks to the bottom.

[0029] Further, chamfers are provided at the ends of the two stop blocks 9 and the clamping blocks 12, facilitating the insertion of the pulling rope into the clamping block 12.

[0030] Embodiment 2:

[0031] As Figures 1-5 shown, the cage framework 7 is square and both sides are bent to form a V-shaped groove 13. During use, when the user puts away the cage, after the cage is folded, by winding and binding the second pulling rope 5 along the surface of the folded cage, and then inserting the H-shaped floating block 6 into the inner side of the wound second pulling rope 5, the effect of folding and binding the cage can be achieved, avoiding the cage from being scattered and stacked, which takes up a large amount of space.

[0032] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
