A limiting rod 10 is fixed to one side of the transmission plate 9. A through groove 11 is opened on the surface of the fixed sleeve 4. A plurality of limiting grooves 12 are opened on the surface of the connecting rod 5. One end of the limiting rod 10 penetrates through the through groove 11 and is slidably connected inside the limiting groove 12. Both sides at one end inside the adjustment groove 8 are fixed with second springs 24. The other end of the second spring 24 is fixed to the transmission plate 9. A sliding rod 16 is slidably connected inside the rotating rod 14. One end of the sliding rod 16 is fixed with a knob 15. A plug rod 18 is fixed to the side of the knob 15 close to the fixed block 7. A plug slot 17 is opened on the top of the fixed block 7. The inside of the plug slot 17 is sleeved with the plug rod 18. By pulling the knob 15 to drive the sliding rod 16 to move upward, the plug rod 18 is disengaged from the inside of the plug slot 17. Furthermore, the knob 15 can be rotated, so that the sliding rod 16 drives the rotating rod 14 to pull the elliptical plate 13 to rotate, so that the elliptical plate 13 no longer blocks the transmission plate 9, and the resilience of the second spring 24 is used to push the transmission plate 9 to drive the limiting rod 10 to disengage from the inside of the limiting groove 12. Then the user can adjust the height of the connecting rod 5, and at the same time, the impeller 6 can be adjusted to a proper position. Then through the above structure, the connecting rod 5 is quickly fixed, realizing the full mixing of water and air, accelerating the dissolution and diffusion of oxygen, improving the sewage treatment efficiency. Especially when treating high-concentration sewage, organic matters and pollutants can be removed faster. The structure is simple and the operation is convenient.
[0022] Referring to Figures 1 - 3 As shown in the figure, in this implementation scheme: second sliding grooves 22 are opened on both sides inside the adjustment groove 8. Second sliding blocks 23 are slidably connected inside the second sliding grooves 22. The other end of the second sliding block 23 is fixed to the transmission plate 9.

[0026] Working principle: The user drives the sliding rod 16 to move upward by pulling the knob 15, so that the insertion rod 18 disengages from the inside of the slot 17. Then, the knob 15 can be rotated, causing the sliding rod 16 to drive the rotating rod 14 to pull the elliptical plate 13 to rotate, so that the elliptical plate 13 no longer blocks the transmission plate 9. The resilience of the second spring 24 is used to push the transmission plate 9 to drive the limiting rod 10 to disengage from the inside of the limiting groove 12. Then, the user can adjust the height of the connecting rod 5 and at the same time adjust the impeller 6 to a proper position. Then, through the above structure, the connecting rod 5 is quickly fixed to achieve sufficient mixing of water and air, accelerate the dissolution and diffusion of oxygen, and improve the sewage treatment efficiency. Especially when treating high-concentration sewage, organic matters and pollutants can be removed faster. The structure is simple and convenient to operate. By setting the structure of the second chute 22 and the second slider 23, the moving direction of the transmission plate 9 can be ensured, and the phenomenon of the transmission plate 9 tilting can be avoided. By setting the structure of the first chute 19 and the first slider 20, the moving track of the sliding rod 16 can be restricted, and it can be avoided that the user pulls the knob 15 to drive the sliding rod 16 to disengage from the inside of the rotating rod 14. By setting the first spring 21, the acting force of the first spring 21 can play a restraining role on the insertion rod 18, and at the same time, when fixing the knob 15, manpower can be saved. By setting the structure of the third chute 25 and the third slider 26 and using the cooperation with the third spring 27, it can play an auxiliary moving role when the user adjusts the height of the connecting rod 5.
