[0007] In a preferred embodiment, a threaded hole is provided in the middle of the sealing sleeve, the connecting column and the sealing plug are integrally formed, and an external thread matching the threaded hole is provided on the outer wall of the connecting column, and the setting of the external thread and the threaded hole facilitates the limiting fixation of the sealing plug.

[0008] In a preferred embodiment, a sealing ring is provided on the inner wall of the sealing sleeve, and a knob is fixedly provided on the end of the connecting column away from the sealing plug. The setting of the sealing ring can conveniently improve the sealing of the connection between the connecting column and the sealing sleeve, and the setting of the knob facilitates the rotation of the connecting column.

[0009] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0010] The utility model opens a liquid discharge port on a bag body, and is provided with a sealing plug, a sealing sleeve and a connecting column. The sealing plug is placed at the liquid discharge port, and the sealing plug is limited and fixed by using the connecting column and the sealing sleeve. When draining, it is only necessary to twist the knob at the bottom end of the connecting column to separate the connecting column from the sealing sleeve, and then separate the sealing plug from the liquid discharge port, and the waste liquid in the bag body can be discharged through the liquid discharge port. There is no need to cut the bag body with scissors, and the operation is simple. BRIEF DESCRIPTION OF THE DRAWINGS
