[0021] Among them, a conical leg pendant is provided at the lower end of the leg 2, and the two ends of the sling 3 are respectively arranged on both sides of the stepper motor 4; in this way, when the device is placed into the silt using a crane, the blood stasis suction group will be in a vertical state, and the heavy leg pendant can ensure that the device is vertically inserted into the silt and will not fall over when the device is running;

[0022] Among them, when the output shaft of the stepper motor 4 is the longest, the lowermost end of the auger blade 5 does not exceed the lowermost end of the leg 2, so that the auger blade 6 is damaged;
