When the user needs to adjust the sampling depth according to the usage requirements, the user can pull out the pin 98 and control the rotation of the rotating disk 97, so that the pulling rope 93 outside the winding roller 92 can be unwound. At the same time, the coiled pipe 95 and the pulling rope 93 are released synchronously, so that the mounting plate 94 drives one end of the coiled pipe 95 to move underwater under the cooperation of the counterweight, thereby adjusting the sampling depth. At the same time, after adjusting the depth, the user can drive the threaded rod 86 to rotate by turning the handwheel. The threaded rod 86 can drive the connecting hose 85 to move through the cooperation of the threaded plate 87 and the support plate 88. And at the same time, the user replaces and adjusts another collection box 71 through the connection head on the connecting hose 85 to collect the water sample, flexibly replaces and connects to different collection boxes 71 to meet different sampling requirements.
