[0031] Embodiment 2

[0032] This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figures 1 to 4 The bottom of the operating tube 703 is fixedly connected with a fixing sleeve 8, and the interior of the fixing sleeve 8 is fixedly connected with the extraction tube 708.

[0033] The working principle of this embodiment is as follows: when liquid passes through the extraction tube 708, the extraction tube 708 is subjected to the impact force of the liquid. Since the extraction tube 708 is too long and the contact area with the operating tube 703 is too small, the extraction tube 708 shakes, which causes the liquid to easily spill when being extracted. This problem can be solved by providing a fixed sleeve 8. By providing the fixed sleeve 8, when the liquid passes through the extraction tube 708, the fixed sleeve 8 fixes one side of the extraction tube 708 to the bottom of the operating tube 703. Under the action of the fixed sleeve 8, the fixed sleeve 8 increases the contact area between the extraction tube 708 and the operating tube 703, thereby avoiding the extraction tube 708 being subjected to the impact force of the liquid when the liquid passes through the extraction tube 708. Since the extraction tube 708 is too long and the contact area with the operating tube 703 is too small, the extraction tube 708 shakes, which causes the liquid to easily spill when being extracted, thereby achieving the purpose of fixing the extraction tube 708 and improving the effect of extracting liquid.
