A plurality of groups of U-shaped support frames 10 are provided on the outside of the threaded shaft 3. Position adjustment components are connected between the outside of the threaded shaft 3 and the plurality of groups of U-shaped support frames 10. The position adjustment components drive the U-shaped support frames 10 to move closer to and away from the outside of the threaded shaft 3.

[0025] The position adjustment assembly includes a positioning ring 5, a threaded ring 6, multiple groups of first brackets 8 and second brackets 9. The positioning ring 5 is fixedly mounted on the outside of the threaded shaft 3 away from the lathe connecting plate 1. The threaded ring 6 is fitted with a threaded movable sleeve on the outside of the threaded shaft 3. Three groups of connecting ears 7 are respectively provided on the outside of the positioning ring 5 and the threaded ring 6. The lower end of the first bracket 8 is rotatably connected to the connecting ear 7 on the outside of the positioning ring 5.

The upper ends of the first bracket 8 and the second bracket 9 are respectively rotatably connected to the bottom of the U-shaped support frame 10.

[0026] Through the above structure, the three groups of U-shaped support frames 10 enter the interior of the pump body, and the driving motor 4 drives the threaded shaft 3, which rotates and drives the threaded ring 6 to move, so that the threaded ring 6 is close to or away from the positioning ring 5. When the threaded ring 6 moves, it drives the three groups of first brackets 8 and second brackets 9 to adjust simultaneously. The specific structure is as follows:

[0027] Combined with attachment Figure 1 and attached Figure 3As shown, a limiting cylinder 13 is integrally formed on the inner side of the bottom of the U-shaped support frame 10, and a limiting rod 14 slides inside the limiting cylinder 13. Three groups of limiting grooves 16 are provided on the lathe connecting plate 1. A disc 15 slides inside the limiting groove 16.

[0034] The specific usage is as follows:

[0035] When the pump casing is clamped and positioned, a pre-positioning wheel 17 of appropriate size is inserted into the inlet and outlet pipes of the pump casing so that the pump casing is sleeved on the outside of the three groups of U-shaped support frames 10. The three groups of U-shaped support frames 10 are driven to move simultaneously by the position adjustment component, and the anti-slip ridges 11 on the two side walls of the U-shaped support frames 10 are supported on the inner side of the pump casing to clamp and position the pump casing.
