Meanwhile, excessive bending of the suction tube 100 to be tested caused by excessive movement of the swinging rod 301 is avoided, and accuracy of test data is affected.

Further, the second inductive element is provided as a position sensor.

In one embodiment, as shown in FIG. 1, a printer 9 and a display screen 10 are provided on the pipette detection device.

Specifically, the display screen 10 displays information such as batch, date and the like of the suction tube 100 to be tested so as to be convenient to record; by installing the printer 9, i.e., the micro thermal printer, it is convenient to print and record the above information.

Although embodiments of the present utility model have been described in connection with the accompanying drawings, various modifications and variations may be made by those skilled in the art without departing from the spirit and scope of the utility model, and such modifications and variations fall within the scope of the utility model as defined by the appended claims.
