A support plate 5 is connected to the bottom end of the I-shaped support 1. A lifting assembly is connected to the lower end surface of the support plate 5, and a limit assembly is installed on the lifting assembly;

[0024] A T-shaped jack 15 penetrating through the I-shaped support 1 is opened in the middle of the I-shaped support 1. A T-shaped positioning pin 14 is inserted into the T-shaped jack 15. A hexagon socket head bolt 3 is screwed on the top of the T-shaped positioning pin 14. A compression gasket 4 is slidably sleeved on the outer wall of the hexagon socket head bolt 3. The top end of the T-shaped positioning pin 14 extends above the I-shaped support 1. The impeller body 2 is slidably sleeved on the part of the T-shaped positioning pin 14 above the I-shaped support 1. The bottom of the T-shaped positioning pin 14 is clamped at the bottom of the T-shaped jack 15 of the I-shaped support 1, and the bottom of the T-shaped positioning pin 14 is connected to the inside of the I-shaped support 1 by screws;

[0025] A fixing hole is opened at the bottom end of the I-shaped support 1, and the support plate 5 is connected to the support plate 5 through bolts from the fixing hole;

[0026] The lifting assembly includes a base plate 6 and two connecting columns 7 symmetrically fixed on both sides of the lower end surface of the support plate 5. Two support columns 12 are symmetrically fixed on the upper end surface of the base plate 6. Lock holes 16 are equally spaced on the two support columns 12. Striped holes 18 are opened on the two connecting columns 7. T-shaped blocks 13 are slidably clamped on the two striped holes 18.
