[0022] A cavity 211 is provided at the top of the burette 21 , one side of the cavity 211 is connected to a first rotating motor 24 , a driving end of the first rotating motor 24 is connected to a worm 25 , the top of the worm 25 is meshed with a worm wheel 26 , and one side of the worm wheel 26 is meshed with a gear rod 22 .

[0023] It should be noted that, in the embodiment, the first rotating motor 24 drives the worm 25 to rotate, thereby driving the worm wheel 26 to rotate, and further driving the gear rod 22 to rise and fall, thereby achieving the entry and outflow of liquid.

[0024] For example, please refer to Figure 3 The flow control assembly 40 includes a second rotating motor 41 connected to one side of the bottom of the bracket 10 and a semicircular ball 42 connected to the driving end of the second rotating motor 41.

[0025] It should be noted that, in the embodiment, the second rotating motor 41 drives the semicircular ball 42 to rotate, thereby controlling the titration speed.
