[0024] As a further embodiment, two fixing plates 9 are fixedly provided on the extension plate 2 , and an auxiliary wheel 10 is rotatably arranged between the two fixing plates 9 .

[0025] As a further embodiment, side handles 8 are fixedly provided on both sides of the mounting plate 4 , and a cross bar 7 is provided at the bottom of the mounting plate 4 .

[0026] As a further embodiment, a torsion spring is provided at the rotational connection position between the handle 3 and the extension plate 2 .

[0027] As a further embodiment, a slider 17 is provided in the internal sliding seal of the detection tube 12, a first spring 18 is connected between the carrier plate 20 and the slider 17, an air inlet 15 and an air outlet 16 are respectively provided at the upper end of the detection tube 12, an air pump 14 is fixed on the frame 1, and the air inlet 15 and the air outlet 16 are respectively connected to the air pump 14.

[0028] As a further embodiment, a retaining ring 23 is fixedly provided inside the lower end of the detection tube 12, and a movable ring 26 is slidably provided at the lower end of the detection tube 12. A second spring 25 is connected between the movable ring 26 and the retaining ring 23. An annular groove 30 is provided inside the movable ring 26, and a cleaning box is clamped in the annular groove 30.

[0029] As a further embodiment, the cleaning box includes a box body 24 and a cover plate 27, the cover plate 27 and the box body 24 are connected by threads, the shape of the cover plate 27 is adapted to the annular groove 30, and it is made of rubber material, and two through holes are provided on the cover plate 27 and the box body 24 so that the humidity detection probe 21 and the pH value detection probe 22 can pass through, and the box body 24 is filled with multiple absorbent cotton balls 28.
