[0023] It should be noted that: in this embodiment, the plug body 1, the anti - detachment portion 4 and the sliding portion 6 are all smooth - surface structures, so as to ensure the seal with the infusion bottle stopper. At the same time, the plug body 1 is a hollow structure for the transmission of liquid medicine.

[0024] In this implementation scheme: the plug body 1 is inserted into the infusion bottle by using the pointed head portion 2, and it is ensured that the anti - detachment portion 4 and the sliding portion 6 are respectively located inside and outside the infusion bottle stopper. The anti - detachment effect of the plug body 1 can be achieved by the contact between the opening portion of the anti - detachment portion 4 and the inner wall of the infusion bottle stopper. The plug body 1 is continuously inserted into the infusion bottle and the sliding portion 6 enters the infusion bottle. At this time, pulling the plug body 1 can quickly pull it out of the infusion bottle.
