When the swab is needed to be smeared, the rod end of the sampling swab 20 is installed on the quick-release interface 13, liquid in liquid discharging flows to the swab part of the sampling swab 20 through the drainage effect of the rod end of the sampling swab 20, and an operator can perform smearing work required by an experiment through the swab part; when the sampling swab 20 is not needed and only the pipetting function of the rapid pipette is needed, the rod end of the sampling swab 20 is detached from the quick release interface 13, and the operator can perform a conventional pipetting operation. Adopt the technical scheme of the utility model, can let operating personnel conveniently paint work when moving the liquid, let operating personnel be convenient for carry out the experiment operation.

As a preferred embodiment, as shown in fig. 1, in the embodiment 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. The contact area between the operation opening 11 and the fingers can be increased by pressing the boss 13, which is helpful for the operator to block the operation opening 11 by the fingers.

More preferably, as shown in fig. 1, in the technical solution of embodiment 1, a tapered structure is formed at the bottom of the tube body 10 from top to bottom, the bottom of the tapered structure is connected to the liquid transfer port 12, and the tapered structure helps the liquid to flow out uniformly and in small strands, thereby facilitating the orderly experiment.

In the embodiment of embodiment 1, it is more preferable that the tube 10 is formed with a scale mark 15, and the operator can see the volume of the liquid in the tube 10 through the scale mark 15 to perform quantitative pipetting.

Preferably, the quick disconnect 13 is a socket corresponding to the end of the sampling swab 20, and the bore of the socket corresponds to the bore of the end of the sampling swab 20, so as to fit the end of the sampling swab 20 in an interference fit.

In the solution of example 1, the swab part is made of flocked, cotton, or a composite material. Specifically, when in use, the material of the wiper portion, in addition to the above materials, may be selected according to actual needs.

Except for the above-mentioned technical scheme of embodiment 1, the utility model provides a technical scheme of embodiment 2 still, in the technical scheme of embodiment 2, the pipette includes body 10, and the top of body 10 is provided with operation mouth 11, and the bottom of body 10 is provided with moves liquid mouth 12, and the bottom of body 10 still is provided with quick detach interface 13, and quick detach interface 13 is close to with moving liquid mouth 12, and the pipette still includes the sampling swab, and the sampling swab is installed on quick detach interface 13. The difference between this embodiment 2 and the above embodiment 1 is that in the technical solution of embodiment 2, the pipette is provided with a sampling swab, and when the liquid taking operation of the liquid outlet 12 can be realized by the finger fitting with the operation port 11, the sampling swab does not affect the liquid taking of the tube body 10. When the swab is needed to be used for smearing, liquid flowing out flows to the swab part of the sampling swab 20 through the drainage effect of the rod end of the sampling swab 20, and an operator can perform smearing work required by an experiment through the swab part; when the sampling swab 20 is not needed and only the pipetting function of the rapid pipette is needed, the rod end of the sampling swab 20 is detached from the quick release interface 13, and the operator can perform a conventional pipetting operation.

As a preferred embodiment, in the solution of example 2, the sampling swab 20 is provided with a frangible portion at the end of the wand. When the sampling swab 20 is not needed to be used and only the pipetting function of the rapid pipette is needed to be used, an operator can also directly perform the conventional pipetting operation by breaking the easy-folding part at the rod end of the sampling swab 20, and the influence of the swab part of the sampling swab 20 on the pipetting function of the rapid pipette is avoided. More preferably, the frangible portion of the rod end of the sampling swab 20 is disposed proximate to the quick release interface 13.

Except for the above-mentioned technical scheme of embodiment 1, the utility model provides a technical scheme of embodiment 3 still, in the technical scheme of embodiment 3, the pipette includes body 10, and the top of body 10 is provided with the operation that is linked together with the inside of body 10 and glues head 16, and the bottom of body 10 is provided with moves liquid mouth 12, and the bottom of body 10 still is provided with quick detach interface 13, and quick detach interface 13 is close to with moving liquid mouth 12, and quick detach interface 13 is used for installing the stick end of sampling swab 20. The difference between this embodiment 3 and the above embodiment 1 is that the liquid taking and discharging operations are performed by directly pressing the rubber head 16 instead of closing the operation opening with a finger. Otherwise, the usage is the same as that of embodiment 1, when the swab is needed to be applied, the rod end of the sampling swab 20 is mounted on the quick-release interface 13, the liquid flowing out will flow to the swab part of the sampling swab 20 by the drainage effect of the rod end of the sampling swab 20, and the operator can perform the application work needed by the experiment through the swab part; when the sampling swab 20 is not needed and only the pipetting function of the rapid pipette is needed, the rod end of the sampling swab 20 is detached from the quick release interface 13, and the operator can perform a conventional pipetting operation. Adopt the technical scheme of the utility model, can let operating personnel conveniently paint work when moving liquid, let operating personnel be convenient for carry out the experiment operation.

Except for the above-mentioned technical scheme of embodiment 1, the utility model provides a technical scheme of embodiment 4 still, in the technical scheme of embodiment 4, the pipette includes body 10, the top of body 10 is provided with the operation that is linked together with the inside of body 10 and glues head 16, the bottom of body 10 is provided with moves liquid mouth 12, the bottom of body 10 still is provided with quick detach interface 13, quick detach interface 13 is close to with moving liquid mouth 12, the pipette still includes the sampling swab, the sampling swab is installed on quick detach interface 13. This embodiment 4 differs from the above-described embodiment 3 in that the pipette is provided with a sampling swab. The operation of taking and discharging liquid is directly realized by pressing the operating rubber head 16, when the swab is required to be used for smearing, the liquid during discharging liquid flows to the swab part of the sampling swab 20 by virtue of the drainage effect of the rod end of the sampling swab 20, and an operator can perform smearing work required by an experiment through the swab part; when the sampling swab 20 is not needed and only the pipetting function of the rapid pipette is needed, the rod end of the sampling swab 20 is detached from the quick release interface 13, and the operator can perform a conventional pipetting operation.

As a preferred embodiment, in the technical means of the example 4, the rod end of the sampling swab 20 is provided with a folding part. When the sampling swab 20 is not needed to be used and only the pipetting function of the rapid pipette is needed to be used, an operator can also directly perform the conventional pipetting operation by breaking the easy-folding part at the rod end of the sampling swab 20, and the influence of the swab part of the sampling swab 20 on the pipetting function of the rapid pipette is avoided. More preferably, the frangible portion of the rod end of the sampling swab 20 is positioned proximally adjacent to the quick release interface 13.

By adopting the technical scheme of the invention, when the swab is required to be smeared, an operator can dip liquid in the swab part of the sampling swab 20 to smear required by an experiment, and after smearing is finished, the sampling swab is taken down and restored to a pipette, so that the sampled liquid can be accurately transferred to a certain volume for detection.
