The first pole guiding chute sections are for guiding the lock part of the slider latch to first pole slot, institute It states the first pole slot and is used for limiting the relative displacement of the lock part of the slider latch to the right, the locking guiding chute sections In being guided the lock part of the slider latch to the lock groove by first pole slot, the lock groove is used for institute The lock part for stating slider latch carries out reverse limit locking, and the second pole guiding chute sections are used for the sliding latch The lock part of part is guided to second pole slot, second pole slot be used to limit the lock part of the slider latch to Right relative displacement, the reset guiding chute sections are for being drawn the lock part of the slider latch by second pole slot It is directed at the first pole guiding chute sections.

6. portable fluid impedometer as claimed in claim 5, it is characterised in that：First pole guides chute sections Downstream part extend to first pole slot, the glide direction phase of extending direction and the slide lock stopping seat from left to right It hands over；

The upstream portion of the locking guiding chute sections is extended using first pole slot as starting point to the left, extending direction and institute The glide direction for stating slide lock stopping seat is parallel, and the downstream part of the locking guiding chute sections extends to the locking from right to left Slot, extending direction intersect with the glide direction of the slide lock stopping seat；

The upstream portion of the second pole guiding chute sections extends to the right using the lock groove as starting point, extending direction and institute The extending direction for stating slide lock stopping seat is parallel, and it is described that second pole guides the downstream part of chute sections to extend to from left to right Second pole slot, extending direction intersect with the extending direction of the slide lock stopping seat；

The upstream for resetting guiding chute sections is extended using second pole slot as starting point to the left, extending direction and the cunning The extending direction of dynamic locking seat is parallel, and the terminal point for resetting guiding chute sections is equipped with non-return boss, and the non-return boss is high Go out the bottom of the first pole guiding chute sections and along the opposite glide direction of the slider latch inversely to the annular The bottom of slideway seamlessly transits, and the end face of the non-return boss guides the right side wall of chute sections to be adapted with first pole.

7. portable fluid impedometer as claimed in claim 5, it is characterised in that：The slider latch is locked for U-shaped One end of only bar, the U-shaped locking rod is rotatably dispose in the fixture base, and the free end sliding of the U-shaped locking rod is set It is placed in the annular groove.

8. portable fluid impedometer as described in any one of claim 1 to 7, it is characterised in that：The response element For the golden finger circuit board equipped at least two pins, and it detects stoste receiving terminal and is equipped with reaction enzymes.

9. portable fluid impedometer as described in any one of claim 1 to 7, it is characterised in that：The response element For the screen printing electrode equipped at least two electrodes, and it detects stoste receiving terminal and is equipped with reaction enzymes.

10. portable fluid impedometer as described in claim 1, it is characterised in that：The human-computer interaction module be by The combination of one or both of key and touch screen.
