Fixed sleeve 411 outer wall is fixed with threaded sleeve 414, threaded sleeve 414 inner wall is threadedly connected with threaded rod 416, movable sleeve 413 outer wall is provided with two groups of holes 415 corresponding with threaded rod 416, two groups of holes 415 are distributed above and below, by rotating threaded rod 416 can make threaded rod 416 respectively embedded in the hole 415 of different height, when movable sleeve 413 is embedded in the chamber 412 inside, can be fixed, when movable sleeve 413 is stretched upwards, also can be fixed.

[0025] The inner part of the fixed baffle 411 is provided with a backing plate 511, which can be used to support the centrifugal pump, and the bottom end of the backing plate 511 is fixed with a movable rod 512 which penetrates the inner part of the detection table 1. By pushing the movable rod 512 upwards, the backing plate 511 can be lifted and the centrifugal pump after pressure detection can be pushed out, which is convenient for the staff to take. The bottom end of the movable rod 512 is fixed with a movable block 513, and the inner part of the movable block 513 is rotatably connected with a roller 515. By pushing the roller 515, the movable block 513, the movable rod 512 and the backing plate 511 can be lifted to achieve better stability. The outer wall of the movable rod 512 is wound with a spring 514, one end of which is connected to the movable block 513 and the other end is connected to the bottom end of the detection table 1. The spring 514 can provide good elasticity. After the movable block 513 is pushed upwards, the spring 514 can be compressed.
