[0030] Working principle: When sampling vegetation, the support frame 1 is connected to the handle 2 and the support frame 1 is connected to the rotating wheel 3 to change the position of the support frame 1.

Under the action of the telescopic rod 16 and the tension spring 15, the plate 13 and the pressing ring 12 are tightly abutted. When the plate 13 is adjusted to a suitable position, the plate 13 is adjusted to the corresponding position. Continue to change the action position of the pressure ring 12 so that the pressure ring 12 is pressed tightly against the ground, and finally start the stepper motor 6 to rotate the screw rod 7 and change the action position.
