The extrusion push rod (36) is connected to the sliding groove of the push plate gear (38), and the push plate gear (38) is connected to the matching pin (37) by rotation, so that the push plate gear (38) forms a toggle guide around the matching pin (37) under the toggle of the extrusion push rod (36). The first rack (33) is driven to derive the bidirectional derivation rack (39) for displacement by meshing the push plate gear (38) with the first rack (33), and the bidirectional derivation rack (39) is meshed and connected with the second toggle gear shaft (41). The second shifting gear shaft (41) is rotated under the meshing and shifting of the bidirectional derivation rack (39), and the meshing connection between the second shifting gear shaft (41) and the second rack (42) is utilized so that the second rack (42) drives the bidirectional push rod (43) under the rotational derivation of the second shifting gear shaft (41), so that the bidirectional push rod (43) is squeezed into the inside of the pressurized air bag (44) and then gradually expands, so that an internal suction negative pressure is formed inside the pressurized air bag (44), so that the computer piston contracts the push rod (46) to rise inside the sampling tube (47) and the guide air pipe (45), thereby forming an auxiliary pumping pressure, and the water sample is sucked into the inside of the sampling tube (47), thereby completing the sampling.
