[0002] Aquaculture is an important part of my country's agricultural economy, and live harvesting is a key step in the grading, sales, and transportation processes of aquaculture. Fishing traps are one of the most commonly used tools in this process.

[0003] Currently, most fishing cages used in aquaculture farms are fixed mesh cage structures. These fishing cages are usually made of metal or plastic frames covered with netting, or directly made of rigid materials with fixed-diameter holes. A search revealed a utility model patent with patent authorization announcement number CN216533362U, which discloses a fish and shrimp catching device for aquaculture, including a scoop ring and a sealing assembly. The scoop ring has a scoop net fixedly connected to its upper inner wall, and a scoop handle fixedly connected to its outer arc front end.

The scoop handle also includes a telescopic motor, a screw, and a battery, with the telescopic motor and battery both located at the front end of the outer sleeve.

[0004] However, when existing fishing gear catches live aquatic organisms in aquaculture ponds, various live aquatic organisms are caught together and then sorted, which is quite troublesome. In addition, traditional fishing cages are usually equipped with handles of fixed length, which is inconvenient when it is necessary to catch live aquatic organisms in the center of the aquaculture pond, deep in the net cage, or in a more distant area. Utility Model Content

[0005] The purpose of this utility model is to provide a live aquaculture trap that solves the problems of poor applicability, fixed length, and inconvenience of use of existing traps.

[0025] Please see Figures 1-5 A mesh adjustment mechanism 3 is provided between the large trap 1 and the small trap 2. This mechanism adjusts the mesh size after the through holes in the large trap 1 and the small trap 2 are misaligned. The mesh adjustment mechanism 3 includes an L-shaped frame 31 fixedly connected to the outer wall of the small trap 2. A locking pin 32 is slidably connected to the vertical part of the L-shaped frame 31, penetrating the L-shaped frame 31. One end of the locking pin 32 is inserted into the outer wall of the large trap 1, and the other end is fixedly connected to a connecting piece 33.

A protruding ring 36 is fixedly connected to the inner wall of the large trap 1, and a ring groove is formed on the outer wall of the small trap 2. The protruding ring 36 is slidably connected to the ring groove. The convex ring 36 provides a vertical limiting function between the large trap 1 and the small trap 2.

[0026] Please see Figure 4 , Figure 6A locking mechanism 8 is provided between the adjusting sleeve 6 and the hollow cylinder 5. The locking mechanism 8 prevents loosening of the adjusting sleeve 6, thereby improving the stability of the adjusting screw 7 after adjustment. The locking mechanism 8 includes a locking disc 81 fixedly connected to the outside of the adjusting sleeve 6, a locking sleeve 82 fixedly connected to the outside of the hollow cylinder 5, a pin 83 slidably connected inside the locking sleeve 82, the pin 83 passing through the locking disc 81 and slidably connected to it, a second spring 84 inside the locking sleeve 82, one end of the second spring 84 fixedly connected to the pin 83, and the other end fixedly connected to the inner surface of the locking sleeve 82, a lever 85 fixedly connected to the pin of the pin 83, and the lever 85 slidably connected to the locking sleeve 82.

[0027] The specific implementation process of this utility model is as follows: In use, firstly, pull the locking pin 32 using the pull ring 34, causing the locking pin 32 to be pulled out of the insertion hole on the outer wall of the large trap 1. At this time, the lock between the small trap 2 and the large trap 1 is released. The operator can rotate the L-shaped frame 31 on the small trap 2 or directly rotate the small trap 2 itself. As the small trap 2 rotates, its through hole misaligns with the through hole on the large trap 1, and the effective mesh size changes accordingly. When the mesh size is observed to meet the current aquatic product specifications for catching, release the pull ring 34. Under the rebound force of the spring 35, the locking pin 32 will automatically spring back and insert into the corresponding new insertion hole on the outer wall of the large trap 1, thereby relocking the small trap 2 and preventing it from rotating on its own. Additionally, if overall adjustment is required... To adjust the length, simply separate the rubber ball 88 from the locking sleeve 82, then release the restriction on the lever 85. The lever 85 then drives the pin 83 to overcome the elastic force of the second spring 84 and disengage it from the hole in the locking disc 81. Then, rotate the adjusting sleeve 6, and the adjusting screw 7 will move axially in the adjusting sleeve 6 under the guidance of the square rod 10. After adjusting to the required length, release the lever 85, and the second spring 84 will push the pin 83 back to its original position, allowing it to insert into the corresponding new hole on the locking disc 81. This will re-fix the adjusting sleeve 6 and the hollow cylinder 5 relative to each other.
