The motor drives the positioning and clamping module 4 to reset; and repeating the above process to enable the pipetting tips on the plurality of middle plates to be arranged in the box body 3-2 in a stacked manner, thereby completing the stacking and boxing of the pipetting tips.
When the middle plate 2 loaded with 200 mul of the pipette tip 6 is stored, the positioning pins 4-2-2 in the positioning holes are taken out, so that the distance between the two limit clamps 4-2-1 is reduced when the positioning clamp module 4 is in the clamped state to accommodate the middle plate with smaller size. The boxing process of the middle plate 2 corresponding to the 200 mu L pipetting tip 6 is the same as the boxing process of the middle plate 2 corresponding to the 1000 mu L pipetting tip 6, and will not be described here.
