This can prevent the adhesive layer 14 from sticking to the patient's body hair and causing discomfort to the patient when removing the device. By using different fixing methods at different positions, the practicality of the device is improved and the patient's comfort is guaranteed.

[0038] It is further explained that connecting rings 16 are fixedly installed on both sides of the base plate 1, a first opening 18 is opened at the upper end of the connecting ring 16, a second opening 19 is opened on the side of the connecting ring 16 away from the base plate 1, a rotating rod 17 is arranged in the connecting ring 16, a connecting plate 20 is fixedly connected to the outer surface of the rotating rod 17, the connecting plate 20 is adapted to the second opening 19, one side of the connecting plate 20 is fixedly connected to the first fixing belt 21, and the other side of the connecting plate 20 is fixedly connected to the second fixing belt 22.
