In the process of implementing this solution, it was discovered that the following problems existed in the prior art, which were not well solved: This device places the medicine bottle on the upper end of the base, and then retracts the telescopic end of the hydraulic telescopic rod to drive the lifting plate down and up and down. The lowering of the plate drives the sleeve to move downward, and the downward movement of the sleeve drives the suction cup to move into the medicine bottle to sample the medicine. However, the medicine bottle and the suction cup need to be aligned to promote the suction cup to be accurately inserted into the inside of the medicine bottle, and the medicine bottle is placed directly on the base. When the device shakes or the operator accidentally touches the medicine bottle, its position is prone to shift, causing the suction cup and the medicine bottle to be misaligned, making it difficult for the suction cup to accurately insert the medicine bottle into the medicine bottle to absorb the medicine.
