[0050] In some other embodiments, the connecting assembly 420 includes a connecting sleeve, which is fixedly connected to the Y-direction moving assembly 320 and sleeved on the adjusting beam 411. When the X-driving member drives the X-moving plate and the Y-moving plate to move along the X-direction, the connecting sleeve slides on the adjusting beam 411, which can ensure the consistency of movement of the two ends of the Y-moving plate while preventing the adjusting beam 411 from being separated from the connecting sleeve.

[0052] In the above embodiment, the corresponding connection components 420 are all provided with limit components. After the relative position of the connection component 420 and the adjustment beam 411 is adjusted, the limit components limit the current relative position of the connection component 420 and the adjustment beam 411 to ensure the subsequent use effect of the pipetting device. Specifically, the limit components can be set as two limit buckles, and both limit buckles can be detachably connected to the adjustment beam 411. After the relative position of the connection component 420 and the adjustment beam 411 is adjusted, the two limit buckles are respectively set on both sides of the connection component 420 and are both connected to the adjustment beam 411, so as to prevent the connection component 420 from shifting along the X direction on the adjustment beam 411.

[0053] Preferably, the pipetting device further includes an intelligent control component, which includes a level sensor and a controller. The level sensor is disposed on the pipetting mechanism 300 , and the controller is connected to the level sensor and the adjustment mechanism 400 .

[0054] Specifically, the horizontal sensor is arranged on the Y movable plate, and is used to monitor the real-time horizontal state of the Y movable plate and transmit it to the controller. When the horizontal sensor detects that the Y movable plate is in a non-horizontal state, the adjustment signal is transmitted to the controller. The controller receives the adjustment signal and sends an adjustment instruction to the adjustment drive component. The adjustment drive component operates according to the received adjustment instruction to drive the adjustment member 412 and the adjustment beam 411 to rise and fall, so that the Y movable plate is adjusted to a horizontal state. After that, the horizontal sensor sends a stop signal to the controller, and the adjustment drive component stops operating, so that the adjustment member 412, the adjustment beam 411 and the Y movable plate remain in the current state. The intelligent control component can realize adaptive adjustment without manual operation, further improving the timeliness and adjustment accuracy of position adjustment.

[0055] In addition, in this embodiment, the pipetting mechanism 300 may also be connected to the controller to achieve linkage between the pipetting mechanism 300 and the adjustment mechanism 400 .
