[0030] Working principle: When it is necessary to adjust the distance between the detection box 201 and the top cover 202, the two sets of second bevel gears 209 can be driven to rotate by rotating the connecting rod 210, and then the second bevel gear 209 can drive the threaded rod 205 to rotate through the first bevel gear 207, so that the threaded rod 205 and the top cover 202 are threadedly rotated, so as to adjust the distance between the detection box 201 and the top cover 202, avoiding the problem that the existing adjustment method is more cumbersome. When it is necessary to test different pressure differences in the two notches 213, the bidirectional screw 303 can be driven to rotate by rotating the handle 302, so that the two sets of moving blocks 304 simultaneously push the support rod 306 to move, thereby realizing the height adjustment of the water tank 311 and realizing the pressure difference test in the two notches 213 at different heights, avoiding the problem of adjusting the height of the water tank 311 by raising the water tank 311 with other materials, thereby improving the convenience of adjusting the height of the water tank 311.
