[0026] Specifically, a plurality of baffles 23 are arranged in a vertical row on the hatching plate 2, and a plurality of grooves are formed between the plurality of baffles 23, which are convenient for fish to lay eggs, and the fish eggs are stored in the grooves. The hatching plates 2 arranged up and down are arranged in layers, which increases the spawning area and is more convenient for water flow, keeps the hatching plate 2 clean, and is convenient for fish egg hatching. The engaging teeth 14 on the support tube 12 can cooperate with the inner tooth grooves 22 in the sleeve 21 to limit the hatching plate 2 and maintain the angle of the hatching plate 2, which can be more convenient for water flow.

[0027] like Figure 3 , Figure 4 , Figure 5A center roller 15 is sleeved inside the support tube 12 shown. A cam 16 is sleeved on the center roller 15 that coincides with the position of the sleeve 21. The cam 16 cooperates with the inner end of the through slot 13. One end of the center roller 15 passes through the side plate 11, and a knob 17 is installed on the outer end of the center roller 15. A limit through hole 131 is also provided inside the through slot 13, and a limit rod 132 is slidably provided inside the limit through hole 131. The limit rod 132 is fixedly connected to the support tube 12. In addition, in order to facilitate the adjustment of the hatching plate 2, the knob 17 can be rotated, so that the cam 16 can be pushed to rotate by the center roller 15. When the cam 16 rotates to be opposite to the through slot 13, the engaging teeth 14 can be pushed outward, so that the engaging teeth 14 are engaged with the inner tooth groove 22, and the hatching plate 2 is locked, which is convenient to adjust.

[0028] like Figure 1 , Figure 2 As shown, an aeration pipe 18 is also installed on the top surface of the base 1.

[0032] When in use, first turn the knob 17, the knob 17 can push the center roller 15 to rotate, and the cam 16 on the center roller 15 will rotate with the center roller 15. When the cam 16 rotates to be opposite to the through slot 13, the bite teeth 14 can be pushed outward, so that the bite teeth 14 are engaged with the inner tooth grooves 22 on the inner wall of the sleeve 21, so that the sleeve 21 and the hatching plate 2 can be restricted to keep the hatching plate 2 stable. When the center roller 15 is rotated in the opposite direction, the cam 16 will be staggered with the through slot 13. At this time, when the bite teeth 14 are contracted into the through slot 13, the restriction of the hatching plate 2 can be released, and the angle of the hatching plate 2 can be adjusted conveniently.

[0033] In addition, in order to make the fish eggs adhere to the hatching plate 2, a plurality of baffles 23 are arranged in a vertical row on the hatching plate 2, and a plurality of grooves are formed between the plurality of baffles 23, so that the fish can lay eggs conveniently, and the fish eggs can be stored in the grooves. The hatching plates 2 arranged up and down are arranged in layers, which increases the spawning area and facilitates the water flow, keeps the hatching plate 2 clean, and facilitates the hatching of fish eggs. The engaging teeth 14 on the support tube 12 can cooperate with the inner tooth grooves 22 in the sleeve 21 to limit the hatching plate 2, maintain the angle of the hatching plate 2, and facilitate the water flow.

[0034] Furthermore, an aeration pipe 18 is installed on the base 1, and the aeration pipe 18 can transport air to the hatching plate 2, thereby increasing the oxygen content in the water and increasing the hatching success rate of the fish eggs.
