[0025] Specifically, by placing the container in the placement slot 6 in the placement table 5, and then driving the fixing seat 203 to rotate through the driving part, and then driving the metering tube 4 to rotate so that its nozzle is facing downward to the container, the liquid in the metering tube 4 is poured into the container, thereby improving work efficiency.

[0026] The driving part includes a motor 204 fixedly mounted on the bracket 201, the output end of the motor 204 is fixedly connected to the transmission shaft 205, the transmission shaft 205 and the rotating shaft 202 are respectively fixedly connected to the main gear 206 and the slave gear 207, a gear plate 208 is slidably mounted on the bracket 201, the gear plate 208 is meshed with the main gear 206 and the slave gear 207, and the motor 204 is electrically connected to the external power supply.

[0027] Specifically, by starting the motor 204, the metering tube 4 is driven to rotate under the transmission of the transmission shaft 205, the main gear 206, the tooth plate 208, the slave gear 207, the rotating shaft 202 and the fixed seat 203, and the angle is adjusted.
