[0008] Furthermore, there are several placement slots, which are arranged in a circular array on the placement rack.

[0009] Furthermore, the placement groove is provided with a sliding groove, and the sliding pad is provided with a slider, and the sliding groove and the slider are slidably connected.

[0010] Furthermore, a limiting protrusion is provided at the bottom of the placement groove.

[0011] Furthermore, a first magnet is fixedly provided at the top of the first electric actuator, and a second magnet is fixedly provided at the bottom of the sliding pad. The first electric actuator is located below the through hole.

[0012] Furthermore, the drive motor is a servo motor.

[0013] Furthermore, the drive assembly includes a first lug fixedly mounted on the top of the cylinder, a second lug fixedly mounted on the cover, and a second electric actuator hinged between the first lug and the second lug.

[0014] The beneficial effects of this utility model are as follows:

[0015] This utility model discloses a pipette holder, which uses a drive motor to drive a rotating holder and is combined with a first electric push rod to lift, so as to achieve precise positioning and automatic lifting of the pipette.
