[0032] A bearing 51 is disposed in the shaft hole 5 and matches with the rotating shaft portion 32 of the T-shaped threaded shaft 3 .

[0033] The working principle of the utility model: when in use, the attachment plate is rotatably arranged on the frame, and the attachment plate can swing slightly on the frame under the action of water flow, so that the light and water permeability between the attachment plates becomes better, which is beneficial to the reproduction of benthic diatoms, thereby improving the ecological environment. The rotation is achieved by the cooperation of the T-shaped threaded shaft and the shaft hole, and the detachable fixation is achieved by the cooperation of the T-shaped threaded shaft and the connecting block. The structure is simple and easy to use, and it is convenient to install and disassemble, and it is convenient to repair and replace the attachment plate, and it is convenient to carry out subsequent operations on the seedlings on the attachment plate; by arranging through holes on the corrugated attachment plate, the area of ​​the attachment plate is increased, the breeding area is increased, and the exchange flow effect of water, oxygen airflow and bait is greatly improved, so that the distribution of water flow, airflow and bait is more even, and the smooth flow of various substances in the nursery pond is guaranteed.
