2. A portable sampling device for water treatment according to claim 1, the method of which comprises the steps of first, rotating; step two, placing; step three, fastening; step four, using; the method is characterized in that:

in the first step, firstly, the lead screw (8) is driven to rotate manually through the rotating block (7), the lead screw (8) is matched and connected with a ball nut embedded and installed on the moving block (16), so that the moving block (16) is driven to be positioned on the lead screw (8) to move by utilizing the rotation of the lead screw (8), meanwhile, the moving block (16) is positioned on the limiting rod (17) to move, so that the moving plate (15) is driven to move by utilizing the rotating movement of the moving block (16), and when the moving block (16) is attached to the bottom end of the limiting rod (17), the rotating block (7) can be stopped rotating;

in the second step, the bottom end of the collecting bottle (14) is manually placed above the top end of the moving plate (15), the bottom end of the collecting bottle (14) is positioned between two limiting strips (31) which correspond to each other, and the collecting bottle (14) is placed between two elastic arc-shaped plates (13) which correspond to each other;

in the third step, the manual reverse rotation rotating block (7) drives the screw rod (8) to rotate reversely, so that the moving block (16) and the moving plate (15) are moved to move reversely, then the collecting bottle (14) placed on the moving plate (15) is driven to move, when the top end of the collecting bottle (14) is located on the inner side of the limiting pipe (12) and one end of the water outlet pipe (10) is located inside the collecting bottle (14), the reverse rotation rotating block (7) can be stopped, so that the collecting bottle (14) and the limiting pipe (12) are clamped and fixed relatively, and the moving plate (15) and the collecting bottle (14) are fixed relatively;

in the fourth step, the bottom cover (21) is manually rotated, the rotation of the bottom cover (21) is utilized to respectively drive the connecting column (23) and the nut block (26) to rotate, the nut block (26) is matched with a thread groove formed in the inner side of the sleeve (24) to drive the nut block (26) to be positioned in the sleeve (24) to rotate and move, so that the distance between the bottom end of the bottom cover (21) and the bottom end of the sleeve (24) is adjusted, and along with the rotation of the nut block (26), the sliding block (30) is positioned in a circular sliding rail fixedly arranged on the nut block (26) to move, the indicating rod (29) and the indicating block (28) are driven to move, and meanwhile, the moving position of the indicating rod (29) is limited by utilizing the arranged sliding hole (18), and then through the distance between the scale mark carved on the through sleeve pipe (24) and the instruction block (28), after the distance between the bottom of bottom (21) and the bottom of sleeve pipe (24) is adjusted, the manual work can stop rotating bottom (21), then the manual work places bottom (21) in the water source that needs to take a sample, and through making the bottom of sleeve pipe (24) and the horizontal plane laminate, make bottom (21) and joint (20) be located in the aquatic, then the manual work opens operation hole (4) and makes power supply (3) carry out power supply treatment to miniature suction pump (1), then utilize miniature suction pump (1) of installation to make the sample water in the water source pass through joint (20) ) The utility model discloses a sampling device, gooseneck (25), miniature suction pump (1) and outlet pipe (10) enter into the inside of receiving flask (14) can, after the sample is accomplished, artifical can stop power (3) carry out power supply treatment to miniature suction pump (1), artifical messenger's the device and sample water source separation afterwards, then drive the removal of movable plate (15) and receiving flask (14) through rotatory turning block (7), can stop rotatory turning block (7) when the top of receiving flask (14) is located the bottom below of spacing pipe (12), make artifical messenger receiving flask (14) and movable plate (15) separation can accomplish sample work afterwards.
