This structure can screen smaller organisms through the screening hole 7, and can also replace the screening plate 6 with different sizes of the screening hole 7, thereby improving the screening effect of the crab cage, and effectively preventing the crab cage from overfishing smaller organisms and causing the depletion of fishery resources.
[0025] See also Figure 1-4 The top of the skeleton 1 is evenly fixed with hanging ears 4, and the number of the hanging ears 4 is three groups. The three groups of hanging ears 4 make it convenient for the user to connect the skeleton 1 with a rope. The inner wall of the bottom end of the skeleton 1 is symmetrically provided with limiting grooves 9, and the outer wall of the annular block 5 is symmetrically fixed with limiting blocks 8.

[0026] Embodiment 2
[0027] See also Figure 5A support rod 17 is fixedly installed inside the skeleton 1, and the support rod 17 improves the fixing effect of the bait box 18. The bait box 18 is fixedly installed inside the support rod 17. A cover 19 is installed on the top of the bait box 18, and the cover 19 improves the sealing effect of the bait box 18. The inner wall of the bait box 18 is evenly provided with emission holes 21, and the emission holes 21 improve the emission effect of the bait odor. The bait box 18 and the cover 19 are threadedly connected, and the fixing effect of the cover 19 is improved by the threaded connection. The outer wall of the cover 19 is evenly provided with anti-skid grooves 20, and the anti-skid effect when the cover 19 is rotated is improved by the anti-skid grooves 20. By setting up structures such as the support rod 17, the bait box 18, the cover 19 and the dispensing hole 21, the cover 19 is rotated and removed after a certain number of turns, and then the bait is placed in the bait box 18. After placing the bait, the cover 19 is restored to its original position. When the crab cage is then placed in water, the smell of the bait will be emitted from the dispensing hole 21. This structure improves the placement effect of the bait, facilitates the operator's use, and also improves the success rate of catching the crab cage.
[0028] Working principle: When using a crab cage, smaller organisms can be screened through the sieve holes 7, and larger organisms can be left in the crab cage after screening. When the user needs to use a crab cage with sieve holes 7 of different sizes, the triangular block 15 can be pulled at the same time, and the triangular block 15 can drive the fixed column 12 to move in the limiting hole 11. The fixed column 12 will drive the circular block 13 to move during the movement. The circular block 13 will push the reset spring 14 to the location of the limiting ring block 16 when moving. After pushing a certain distance, the fixed column 12 and the circular block 13 will release the restriction on the ring block 5. After releasing, the ring block 5 is separated from the frame 1, and the sieves with different sizes of sieve holes 7 are replaced after separation. After the split plate 6 is replaced, the limiting block 8 on the outer wall of the annular block 5 is aligned with the limiting groove 9 on the inner wall of the skeleton 1, and then the limiting block 8 is inserted into the limiting groove 9. After a certain distance, the triangular block 15 is pulled at the same time. By pulling the triangular block 15, the fixing column 12 and the circular block 13 release the restriction on the annular block 5, and then the skeleton 1 will slide down along the outer wall of the annular block 5. After sliding the limit distance, the triangular block 15 is released, and then the reset spring 14 will bounce the fixing column 12 and the circular block 13 into the deepest part of the limiting hole 11 to fix the annular block 5. When it is necessary to add bait to the crab cage, the lid 19 can be turned, and the lid 19 can be removed after a certain number of turns, and then the bait can be put into the bait box 18. After putting it in, the lid 19 is restored to its original position. When the crab cage is then put into the water, the smell of the bait will be emitted from the emitting hole 21, thereby increasing the success rate of capture.
