[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0017] It should be noted that in the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "inner", "outer", "upper", "lower", "both sides", "one end", "the other end", "left", "right", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present utility model.

[0018] Please refer to Figures 1-4, the present utility model provides a technical solution: a metal gear blade that is easy to adjust, including a gear 1, a chute 2, a clamping groove 3, a blade 4, a locking bolt 5, and a sliding plate 6. A plurality of chutes 2 are evenly arranged along the radial direction on both sides of the gear 1. The outer ends of the chutes 2 are all connected to the outside of the gear 1. Clamping grooves 3 are arranged on both sides of the chute 2. There are a plurality of blades 4, and the blades 4 are slidably arranged in each chute 2 and fixed by locking bolts 5. Sliding plates 6 are respectively arranged on both sides of the blade 4. The sliding plates 6 on both sides of the blade 4 are slidably arranged in the clamping grooves 3 on both sides of the chute 2. The thickness of the sliding plate 6 is the same as the thickness of the clamping groove 3, and the width of the sliding plate 6 is the same as the width of the clamping groove 3. The cross-section of the blade 4 is an "L" - shaped structure. At least two screw holes 7 are opened at one end of the blade 4 that cooperates with the chute 2. The locking bolt 5 cooperates with the screw holes 7 opened on the blade 4. The width of one end of the blade 4 that cooperates with the chute 2 is the same as the width of the chute 2. A drain hole 8 is opened at one end of the blade 4 perpendicular to the gear 1. A shaft hole 9 is penetrated and opened at the central position of the gear 1. Fixing holes 10 are also penetrated and opened on both sides of the gear 1 at the shaft hole 9.

[0019] Usage method and principle: Insert each blade 4 into the chute 2 from the outside to the inside, and make the sliding plates 6 on both sides of the blade 4 slide into the clamping grooves 3 on both sides of the chute 2. Subsequently, according to specific requirements, that is, the moving speed of the aerator in the water, adjust the positions of each blade 4. The farther the blade 4 is from the outer end, the faster the moving speed. Then, fix each blade 4 in the chute 2 through the locking bolt 5. Finally, connect the gear 1 to the drive shaft. Drive the gear 1 to rotate through the drive shaft, and then pump water through the blade 4, so that while the blade 4 is used as the moving main body, oxygenation can be achieved. The structure of the present utility model is reasonable. Chutes 2 are arranged on both sides of the gear 1, clamping grooves 3 are arranged on both sides of the chute 2. The blade 4 is slidably arranged in the chute 2 through the sliding plate 6 and fixed by the locking bolt 5. The radius of the blade 4 can be adjusted, so that the water pumping depth of the blade 4 can be adjusted, and thus the overall moving speed and oxygenation depth can be adjusted. The operation convenience is greatly reduced, and the flexibility is greatly improved.
