Two L-shaped plates 3 are fixedly connected to the left and right sides of the horizontal plate 25.

[0019] Working principle: When the device starts working, the operator holds handle 2, which moves the electrochemical sensor detection device body 1. When the electrochemical sensor detection device body 1 moves to the octagon, the horizontal plate 25 is placed on the surface of the fixed plate 30. Then, the threaded rod 31 is taken out and threaded through the fixed plate 30 and the horizontal plate 25 to install the horizontal plate 25. The horizontal plate 25, together with the four L-shaped plates 3, will support the electrochemical sensor detection device body 1. Then, a small amount of octagon is taken and inserted into the connecting cylinder 6 through the opening between the cross plate 12 and the connecting cylinder 6. The octagon is placed on the top of the filter disc 16. The motor 10 is started, and the motor 10 drives the transmission rod 11 to rotate. The transmission rod 11 drives the fixed ring 17. The crushing rod 13 rotates, crushing the octagon inside the connecting cylinder 6 to homogenize it and increase the reaction contact area. Then, one of the safety acid-adding bottles 20 is removed from inside the semi-circular block 8. The safety acid-adding bottle 20 moves the connecting ring 21 and the sealing plug 22. The safety acid-adding bottle 20 contains a single-use dose of acid. This single-use dose of acid is slowly poured into the connecting cylinder 6. Organic matter in the octagon, such as cellulose, oils, and proteins, will be decomposed, and heavy metal elements will be released and converted into soluble ionic forms. After cooling for a period of time, ultrapure water is added into the connecting cylinder 6, and the motor 10 is started. The motor 10 drives the transmission rod 11 and the crushing rod 13 to proceed... The motor 10 rotates, and the crushing rod 13 stirs and mixes the material inside the connecting cylinder 6. Then, the motor 10 is turned off, allowing the material inside the connecting cylinder 6 to settle. After a period of settling, the motor 10 is moved upward. The motor 10 drives the cross plate 12 upward through the fixing ring 17. The motor 10 drives the transmission rod 11 and the crushing rod 13 upward. After the transmission rod 11 reaches its limit position, the fixing plate 19 contacts the bottom of the cavity inside the transmission rod 11. The transmission rod 11 then drives the connecting rod 18 upward through the fixing plate 19. The connecting rod 18 drives the filter plate 16 upward. The filter plate 16 removes and filters the impurities inside the connecting cylinder 6, leaving the filtered liquid sample inside the connecting cylinder 6. Finally, the operator moves upward. The connecting cylinder 6, which moves the elastic belt 23, is positioned at the top of the electrochemical sensor detection device body 1. The bottom end of the tapered tube 28 is placed in the detection groove 4. The Z-shaped plate 14, in conjunction with the first arc-shaped plate 7, supports the connecting cylinder 6. The first bolt 15 facilitates the installation and removal of the Z-shaped plate 14. The valve 29 is opened, allowing the liquid sample inside the connecting cylinder 6 to enter the electrochemical sensor detection device body 1 through the detection groove 4. The electrochemical sensor detection device body 1 then detects the liquid sample, and the detection data is displayed on the front screen. The interface 5 transmits the detection data and charges the electrochemical sensor detection device body 1. During the crushing operation of the octagon by the connecting cylinder 6…The second arc-shaped plate 24, in conjunction with the arc-shaped block 32, limits the position of the connecting cylinder 6. After the operation is completed, the Z-shaped plate 14 is disassembled, and the semicircular block 8 is moved upward. The semicircular block 8 drives the T-shaped block 9 to move upward, and the semicircular block 8 drives the safety acid-adding bottle 20 to move. At the same time, the second bolt 27 is rotated and removed from the inside of the electrochemical sensor detection device body 1 and the elastic band 23, allowing the connecting cylinder 6 to be disassembled and its interior cleaned.
