Taking the embodiment shown in fig. 1 as an example, the pipette 200 is U-shaped in overall shape and includes two opposing side arms, one forming a handle 201 and the other forming a muzzle 204. Wherein, a first switch 202 and a second switch 203 are arranged on the handle 201. When the handle 201 is held in the hand, the first switch 202 is preferably located below the second switch 203. And in order to accommodate the normal thinking of the operator, it is preferable that the first switch 202 is set as a low speed switch and the second switch 203 is set as a high speed switch. When the first switch 202 is pressed, it corresponds to drawing liquid at a lower speed, or to drawing liquid of a lower viscosity. When the second switch 203 is pressed, it corresponds to sucking the liquid at a higher speed, or to sucking the liquid of a higher viscosity.
When the pipette gun 200 is laid flat on the base 101, the muzzle 204 extends in a horizontal direction, so that the pipette 300 placed on the muzzle 204 is also placed in a horizontal direction. At this time, a droplet which may be dropped from the liquid outlet of the pipette 300 will be received by the liquid receiving device 103, so as not to be dropped and cause pollution.
In this embodiment, the pipette gun rack 100 further includes a telescopic structure 102, one end of the telescopic structure 102 is connected to the base 101, and the other end of the telescopic structure 102 is connected to the liquid receiving device 103, and the liquid receiving device 103 is driven to move away from or close to the base 101 by the telescopic structure 102.

In another embodiment, the telescopic structure 102 is a telescopic rail, which includes a plurality of sub-rails stacked on each other, and the telescopic rail can be stretched and contracted by matching the plurality of sub-rails. The liquid receiving means 103 is arranged to be slidable along said telescopic guide. During operation, the telescopic guide rail is pulled open to a proper length, and then the liquid receiving device 103 slides to the lower part of the liquid outlet of the pipette 300 along the telescopic guide rail to receive liquid. Optionally, the adjustment of the position of the liquid receiving device 103 by the telescopic guide rail is one-dimensional, that is, the telescopic guide rail can only be extended or retracted in the horizontal direction, so that the liquid receiving device 103 can only be moved in the horizontal direction under the guidance of the telescopic guide rail, so as to reduce the interference between the pipette 300 and the liquid receiving device 103.
Further, in the present embodiment, the base 101 is provided with a receiving opening 104, and the liquid receiving device 103 can be received in the base 101 through the receiving opening 104.
