Both sides of the patch 2 are respectively connected with fixing belts 4 for fixing to the human body. The bag body 11 is sleeved on the outside of the connecting seat 3 and is detachably connected to the connecting seat 3.

[0025] In this embodiment, the drawstring storage bag 1 is similar to the conventional drawstring garbage bags on the market. After use, the opening of the bag body 11 can be shrunk by pulling the drawstring 12. It is a conventional structural design. In this technical solution, the opening of the bag body 11 can be shrunk and bound to the outside of the connecting seat 3 by pulling the drawstring 12, so as to achieve connection and cooperation with the connecting seat 3, and eliminate the conventional skin bonding design. During the replacement process, there will be no direct contact with human skin, and the skin will not be torn, thereby avoiding damage to the skin and having better safety.

[0026] Embodiment 2: Figures 2 to 4As shown, the rest of the parts are the same as those in the first embodiment, except that the connecting seat 3 includes a cylinder 31 connected to the central hole 21, one end of the cylinder 31 is connected to the patch 2, and the outer side of the cylinder 31 is provided with a mounting groove 32 and at least two fixed hooks 33, the mounting groove 32 and the fixed hooks 33 are evenly spaced along the circumferential direction, and a movable hook 34 and an elastic member 35 are provided in the mounting groove 32, the head of the movable hook 34 is received in the mounting groove 32 or extends out of the mounting groove 32, and the elastic member 35 is used to drive the head of the movable hook 34 to extend out of the mounting groove 32, the bag body 11 is sleeved on the cylinder 31, and the movable hook 34 and the fixed hook 33 are both extended into the bag body 11.

[0027] In this embodiment, two or three fixing hooks 33 are provided, preferably three, so that the connection effect is more stable.

[0028] When putting on the drawstring storage bag 1, first put the bag body 11 onto the cylinder 31 and cover the movable hook 34 and the three fixed hooks 33, then pull the drawstring 12 to shrink the opening of the bag body 11 and match it with the outer side of the cylinder 31, and finally tie the drawstring 12 to prevent it from loosening. At this time, since the movable hook 34 and the three fixed hooks 33 are all located in the bag body 11, they can prevent the bag body 11 from detaching from the cylinder 31, thereby playing a restraining role.

[0029] When the drawstring storage bag 1 needs to be replaced, the movable hook 34 is pressed to shrink it, and then the portion of the bag body 11 corresponding to the movable hook 34 is separated from the cylinder 31. At this time, the opening of the bag body 11 lacks restraint, and the opening of the bag body 11 can expand laterally, that is, it can be separated from the fixed hook 33 and finally separated from the cylinder 31.
