Males can reach 40 cm in length and weigh 600 grams; females are slightly smaller, about 25 cm in length and weigh 200 grams. Their body color is pale bluish-green with brownish-yellow markings. Mature males often have a bright blue second walking leg that exceeds their body length. The body is divided into a cephalothorax and abdomen. The cephalothorax is large, tapering towards the abdomen, which has five pairs of walking legs, the first and second pairs being claw-like.

[0003] In existing technologies, when installing net cages for raising giant freshwater prawn larvae, it is usually necessary to prioritize water areas with clean water quality, stable water sources, and small waves. The net is then installed inside the frame. However, in order to improve the tightness of the installation, multiple sets of connecting structures are usually used for connection. When disassembling, workers need to disassemble each connecting structure in order to remove the net, which is quite cumbersome. Utility Model Content

[0022] The overall effect of Embodiment 1 is that when disassembling the net bag 2, the worker rotates the handle 26, which drives the first threaded rod 25 to rotate, causing the first threaded rod 25 to descend along the first threaded hole 24, thereby driving the lifting ring 27 to descend. At this time, the inclined surfaces of multiple push plates 28 contact multiple moving plates 19 respectively, and the push plates 28 can push the moving plates 19 to move, thereby driving the locking block 17 to leave the locking slot 23. At this time, the worker can pull the insert plate 22 out of the socket 13, thus removing the net bag 2 and improving the disassembly efficiency.

[0023] Example 2, as Figures 1-6 As shown, a protective frame 3 is further provided on the top of the frame 1, and a connecting plate 35 is fixedly installed on the outer wall of the protective frame 3. A connecting groove 36 is provided on the outer wall of the connecting plate 35.

[0024] Furthermore, a mounting base 4 is fixedly installed on the top of the frame 1. A control groove 29 is opened on the top of the mounting base 4. A fixing groove 30 is opened on the inner wall of the control groove 29. A second threaded hole 31 is opened through the inner wall of the fixing groove 30. A second threaded rod 32 is threadedly connected inside the second threaded hole 31. A handle 33 is fixedly installed on one end of the second threaded rod 32. A control block 34 is movably connected to the other end of the second threaded rod 32.

[0025] Furthermore, two support seats 5 are fixedly installed on both sides of the frame 1. A storage groove 37 is opened on the inner wall of the support seat 5. A second spring 38 is fixedly installed on the inner wall of the storage groove 37. A storage plate 39 is fixedly installed on one end of the second spring 38. A connecting rod 40 is fixedly installed on the outer wall of the storage plate 39. One end of the connecting rod 40 passes through the support seat 5 and is fixedly installed with a pull plate 41.

[0026] Furthermore, a support rod 6 is slidably installed inside the support base 5, and multiple evenly distributed adjustment grooves 42 are opened through the outer wall of the support rod 6.

[0027] Furthermore, a baffle 20 is fixedly installed on the outer wall of the movable plate 19 to prevent dust from entering the limiting groove 15.

[0028] Furthermore, a mounting plate 7 is fixedly installed on the outer wall of the frame 1, and two first mounting holes 8 are opened through the top of the mounting plate 7.

[0029] Furthermore, a mounting groove 10 is provided at the outer end of the frame 1 away from the mounting plate 7, and two second mounting holes 11 are provided on the inner wall of the mounting groove 10.

[0030] Furthermore, two positioning rods 9 are fixedly installed on the outer wall of the frame 1, and two positioning grooves 12 are opened at the outer end of the frame 1 away from the mounting plate 7 for easy positioning.

[0031] Furthermore, the outer wall of the lifting ring 27 is fitted against the inner wall of the frame 1 to prevent the lifting ring 27 from rotating when the first threaded rod 25 rotates.

[0032] The effect achieved by the entire embodiment 2 is that when installing the protective frame 3, the worker inserts the connecting plate 35 into the control groove 29, and then the worker turns the handle 33. The handle 33 drives the second threaded rod 32 to rotate, and the control block 34 moves along the fixing groove 30 until it enters the interior of the connecting groove 36. In this way, the connecting plate 35 can be fixed. At this time, the protective frame 3 can raise the frame 1, and the inclined inner wall can prevent the giant freshwater prawn from escaping.

[0033] Working principle: When installing frame 1, the worker inserts support rod 6 into the bottom of the water area, and then pulls pull plate 41. Pull plate 41 drives storage plate 39 into storage slot 37 through connecting rod 40. Second spring 38 is compressed, and support seat 5 is fitted onto the outer wall of support rod 6. When frame 1 is adjusted to a suitable height, the worker releases pull plate 41. The elastic force of second spring 38 pushes storage plate 39 into adjustment slot 42, thus completing the installation. Then, the worker places the net bag 2 inside the frame 1 and inserts the insert plate 22 into the socket 13. The insert plate 22 contacts the inclined surface of the locking block 17, and the locking block 17 is squeezed into the limiting groove 15. The first spring 16 is compressed. When the locking groove 23 moves next to the locking block 17, the elastic force of the first spring 16 pushes the locking block 17 into the locking groove 23, thus completing the installation. When installing the protective frame 3, the worker inserts the connecting plate 35 into the control groove 29, and then turns the handle 33. The handle 33 drives the second threaded rod 32 to rotate, and the control block 34 moves along the fixing groove 30 until it enters the connecting groove 36, thus fixing the connecting plate 35. At this time, the protective frame 3 can raise the frame 1, and the inclined inner wall can prevent the giant freshwater prawn from escaping. When connecting, the worker inserts the two positioning rods 9 on the other frame 1 into the two positioning grooves 12 respectively, and the mounting plate 7 enters the mounting groove 10. Then, the worker uses bolts to pass through the first mounting hole 8 and the second mounting hole 11, thus completing the connection. When disassembling the net bag 2, the worker rotates the handle 26, which drives the first threaded rod 25 to rotate, causing the first threaded rod 25 to descend along the first threaded hole 24, thereby driving the lifting ring 27 to descend. At this time, the inclined surfaces of multiple push plates 28 contact multiple moving plates 19 respectively, and the push plates 28 can push the moving plates 19 to move, thereby driving the locking block 17 to leave the locking slot 23. At this time, the worker can pull the insert plate 22 out of the socket 13, thus removing the net bag 2 and improving the disassembly efficiency.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
