Since the process of inserting the puncture needle into the package only needs to control the pressurization between the drive structure and the upper seat outer sleeve and the extraction device upper seat, the operator is more convenient to use, and the operation space for controlling the insertion of the puncture needle into the package is also reduced.

[0009] As a preferred embodiment, the drive structure includes an annular groove arranged on the outer wall of the extraction device upper seat, which forms a sealed hydraulic chamber with the upper seat outer sleeve. A water supply component is arranged on the upper seat outer sleeve to supply water to the hydraulic chamber. A limiting component is arranged above the upper seat outer sleeve to prevent the extraction device upper seat from being lifted upward when the water supply component supplies water.

[0010] With the above scheme, the water supply component can supply water to the hydraulic chamber to increase the hydraulic pressure inside the hydraulic chamber. When the hydraulic pressure in the hydraulic chamber increases, the upper seat outer sleeve will be pressed to move towards the extraction device lower seat.

[0013] As a preferred embodiment, the limiting component includes at least one limiting rod arranged above the extraction device upper seat. The limiting rod is fixed to the extraction device lower seat at both ends through a connecting plate.

[0014] With the above scheme, the limiting rod can limit the pressure lifting of the upper seat of the extraction device when the water supply component is pressurized in the hydraulic chamber. Since the upper seat of the extraction device cannot move upward when it is pressurized, the upper seat sleeve outside the upper seat will be pressed downward as the hydraulic chamber continues to be pressurized. At this time, the piercing needle arranged on the upper seat sleeve will gradually approach the placement cavity and gradually pierce into the packaging placed in the placement cavity.

[0015] As a preferred, a reset component is arranged between the lower seat and the upper seat sleeve of the extraction device to reset the upper seat sleeve when the driving structure is depressurized.

[0016] As a preferred, the reset component includes a reset spring arranged between the lower seat and the upper seat sleeve of the extraction device.

[0017] With the above scheme, the reset spring can reset the upper seat sleeve when the driving structure releases the water pressure between the upper seat sleeve and the upper seat of the extraction device. At this time, the piercing needle arranged on the upper seat sleeve will be away from the placement cavity.

[0018] As a preferred, a guide component is arranged between the lower seat and the upper seat sleeve of the extraction device to guide the movement of the upper seat sleeve.

[0019] As a preferred, the guide component includes a guide column protruded on the lower seat of the extraction device and a guide insertion hole arranged on the upper seat sleeve for the guide column to guide insertion. The guide column and the guide insertion hole are provided with a plurality of pairs, and each guide column is sleeved with a reset spring.

[0020] With the above scheme, the guide column arranged on the lower seat of the extraction device can be inserted into the guide insertion hole on the upper seat sleeve. When the upper seat sleeve approaches or moves away from the lower seat of the extraction device, the guide column will move in the guide insertion hole, thereby guiding the movement of the upper seat sleeve. The reset spring is sleeved outside the guide column, which can facilitate the installation of the reset spring and also can reduce the probability of the reset spring falling off between the upper seat sleeve and the lower seat of the extraction device.

[0021] The utility model discloses due to adopt above technical scheme, have remarkable technical effect: the driving structure that sets up can drive the upper seat sleeve to move to the direction of approaching the lower seat of the extraction device when pressurizing, make the piercing needle on the upper seat sleeve approach the placement cavity and gradually insert the packaging that is in the placement cavity, because the process that the piercing needle inserts the packaging only needs to control the driving structure to pressurize between the upper seat sleeve and the upper seat of the extraction device, make the operator use more convenient, can also reduce the operation space when controlling the piercing needle inserts the packaging.
