The pipette further comprises a foldable swab 20, the foldable swab 20 comprises a hollow first rod end 21 and a first swab part 22 arranged at the head of the first rod end 21, the tail of the first rod end 21 is arranged on the liquid outlet 12 and communicated with the liquid outlet 12, and a foldable part is arranged near the tail of the first rod end 21.

By applying the technical scheme of the utility model, the liquid taking operation and the liquid discharging operation of the liquid outlet 12 can be realized by matching the fingers with the operation port 11. When the swab is required to be used for smearing, the swab is used for dipping liquid and then smearing the liquid; after the smearing is finished, when the pipetting function of the quick pipette is needed, the foldable swab 20 can be separated from the tube body 10 by breaking the easily-folded part at the tail part of the first rod end 21, and the operator can perform conventional pipetting by opening the liquid outlet. By adopting the technical scheme of the utility model, the pipetting operation can be conveniently carried out after the smearing by an operator, and the experimental operation can be conveniently carried out by the operator.

As an alternative implementation manner, in the technical solution of this embodiment, the first rod end 21 is only hollow at the tail, where the hollow structure has the function of enabling the first rod end 21 left in the liquid outlet 12 to be discharged after the frangible portion is broken. As another alternative embodiment, the first rod end 21 may be entirely hollow.

As a preferred embodiment, as shown in fig. 1, in the technical solution of example 1, the operation port 11 is formed with a pressing boss 13, and the pressing boss 13 is used for pressing contact with a finger.
