A first threaded hole 412 is provided on one side of the base 41, which is connected to the slide hole 411. A first jackscrew 413 is screwed into the first threaded hole 412. By tightening the first jackscrew 413, the slide rod 42 is fixed in the slide hole 411, thereby achieving bottom support.

[0021] In another embodiment, the centering mechanism 3 includes a support seat 31, on which a slide groove 32 is fixedly provided; a slider 33 is axially slidably provided in the slide groove 32, and a support sleeve 34 is longitudinally slidably provided; the support sleeve 34 is provided above the slider 33; a first inclined surface 331 is provided on the top of the slider 33, and a second inclined surface 341 adapted to the first inclined surface 331 is provided at the bottom of the support sleeve 34; studs 321 are fixedly provided at the four corners of the bottom of the slide groove 32, and a first through hole 342 adapted to the stud 321 is provided on the support sleeve 34; the stud 321 passes through the corresponding first through hole 342 and is screwed with a first nut 36; the A second threaded hole 322 is provided at both axial ends of the slide groove 32, the second threaded hole 322 is communicated with the interior of the slide groove 32, and a second top screw 37 is screwed into the second threaded hole 322; the second top screw 37 is used to limit the sliding position of the slider 33; the support sleeve 34 is provided with a second through hole 343 on the side away from the volute body 1, and the second through hole 343 is communicated with the interior of the support sleeve 34; a support rod 35 is slidingly provided in the support sleeve 34; one end of the support rod 35 is fixedly connected to the inner ring of the spherical bearing 22 on one side of the volute body 1, and the other end is fixedly connected to a screw 351; the screw 351 passes through the second through hole 343 and is screwed with a second nut 39.
