Further, the pipettor placing part comprises a plurality of U-shaped clamping grooves, the sizes of the U-shaped clamping grooves can be set according to actual conditions, and the sizes of the U-shaped clamping grooves can be the same or different, so that the pipettors with different specifications and functions can be suitable for the pipettors with different specifications and functions.

Further, a clamping piece groove is formed in the inner side of the pipettor placing portion, a clamping piece used for clamping the pipettor is arranged in the clamping piece groove, the clamping piece is connected with the clamping piece groove through a spring, the clamping piece protrudes outwards from the clamping piece groove in a natural state, and when the pipettor is fixed, an internal spring is compressed, and the clamping piece is inwards concave and clamped to clamp the pipettor.

Preferably, the clamping piece is in a double-sphere shape, so that the contact area of the liquid transfer device can be increased, the friction force is improved, the liquid transfer device can be more stably fixed in the U-shaped clamping groove, and the clamping piece can also adopt other shapes which are attached to the liquid transfer device.

Furthermore, the clamping piece is made of elastic materials, deformation can be generated by extrusion, the clamping piece can be better used for pipettors of different specifications, and the clamping piece is coated with a layer of smooth rubber to avoid scraping the surface of the pipettor.

The utility model has the following advantages:

the pipettors of different specifications and models can be placed as required, the pipettors can be fixed on the pipettor frame, the pipettors are prevented from falling and being damaged under the conditions of taking the pipettors, cleaning, moving the pipettor frame and the like, and the two purposes are achieved at one stroke. Simultaneously, the pipettor portion of placing on the pipettor backup plate can be controlled according to the use needs and adjust, can furthest improve the utilization ratio of pipettor frame, and the laboratory space is saved in placing of the great multichannel pipettor of adaptation single channel or width simultaneously.
