[0022] In the above structure, by installing the support ring 3 on the outer wall of the support rod 2, the outer wall of the rotating seat 4 can be restricted under the action of the support rings 3 on the upper and lower sides, so that the outer wall of the rotating seat 4 can only rotate on the outer wall of the support rod 2, thereby making it possible to flexibly adjust the use angle of the rotating seat 4.

[0023] In a preferred embodiment, the inner wall diameter of the rotating seat 4 matches the outer wall diameter of the support rod 2 , and the outer wall diameter of the support ring 3 is larger than the inner wall diameter of the rotating seat 4 .

[0024] In the above structure, the support ring 3 is arranged on the outer wall of the support rod 2, and the outer wall of the rotating seat 4 can be supported and restricted under the action of the support ring 3, so that the rotating seat 4 can only rotate left and right on the outer wall of the support rod 2, thereby realizing flexible adjustment of the use position of the rotating seat 4.

[0025] In a preferred embodiment, an inner wall of the lifting plate 11 is provided with an internal thread, and the inner wall thread of the lifting plate 11 is engaged with the outer wall thread of the driving screw 10 .

[0026] In the above structure, through the internal thread opened on the inner wall of the lifting plate 11, when the servo motor 9 rotates, it can drive the driving screw 10 to rotate. At this time, the lifting plate 11 can be driven under the action of the rotation of the driving screw 10, so that the lifting plate 11 can move up and down along the outer wall of the driving screw 10, so that the outer wall of the culture dish 12 is closer to the bottom of the pipetting device 7.

[0027] In a preferred embodiment, a movable hole is formed in the inner cavity of the lifting plate 11 , and the inner wall diameter of the movable hole matches the outer wall diameter of the limiting rod 8 .

[0028] In the above structure, a movable hole is opened in the inner cavity of the lifting plate 11, and the outer wall of the limit rod 8 passes through the inner cavity of the lifting plate 11, thereby restricting the lifting plate 11, so that the lifting plate 11 can only move up and down along the outer wall of the limit rod 8 under the drive of the driving screw 10 to adjust the use height of the lifting plate 11.

[0029] In a preferred embodiment, the height of the support platform 13 is less than the support height of the support frame 6 , there are two support platforms 13 , and the two support platforms 13 are respectively installed on both sides of the outer wall of the support base 1 .

[0030] In the above structure, the support platforms 13 are arranged on both sides of the outer wall of the support base 1, and the height of the support platforms 13 is lower than the support height of the support frame 6. When the rotating seat 4 rotates, after rotating ninety degrees, the top of the pipetting device 7 can be aligned with the slide 14 on the top of the support platform 13. At this time, the cell fluid can be dropped onto the top of the slide 14 through the pipetting device 7 to realize the extraction of the cell fluid.

[0031] In a preferred embodiment, a control board is installed on the top of the support base 1 , and the control board is electrically connected to the servo motor 9 , and the driving screw 10 passes through the outer wall of the rotating base 4 and is connected to the power output shaft of the servo motor 9 .

[0032] In the above structure, the servo motor 9 can be controlled by a control board installed on the top of the support base 1. When the cell fluid is extracted by the pipetting device 7, the support height of the lifting plate 11 is adjusted under the action of the servo motor 9, so that the lifting plate 11 is closer to the bottom of the pipetting device 7. When the cell fluid needs to be dropped onto the top of the slide 14, the height of the lifting plate 11 is lowered and the rotating seat 4 is rotated.

[0033] Working principle: During the use of the above-mentioned device, when it is necessary to extract the cell fluid, the cell fluid in the inner cavity of the culture dish 12 needs to be extracted and dripped onto the top of the slide 14. At this time, the rotating seat 4 is rotated so that the outer wall of the rotating seat 4 is staggered with the outer wall of the support platform 13. Then, the servo motor 9 is started, and the driving screw 10 is driven to rotate under the action of the servo motor 9, so that the lifting plate 11 moves upward along the outer wall of the driving screw 10, so that the outer wall of the culture dish 12 is close to the bottom of the pipetting device 7. At this time, the cell fluid can be aspirated very conveniently. Take, then, start the servo motor 9 again, and lower the height of the lifting plate 11 under the action of the servo motor 9, but at this time the outer wall of the lifting plate 11 and the bottom of the pipetting device 7 are still in the same vertical plane. If the cell fluid remaining at the bottom of the pipetting device 7 drips downward, it will still drip into the inner cavity of the culture dish 12, and then rotate the rotating seat 4. When the bottom of the pipetting device 7 rotates to coincide with the top of the support platform 13, the pipetting device 7 is pressed at this time to make the cell fluid in the inner cavity of the pipetting device 7 drip onto the top of the slide 14, thereby realizing the extraction of the cell fluid.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
