In the above-mentioned scheme, on the one hand, in the rotation process of first scraping membrane portion 210 and second scraping membrane portion 220, both do not only roll on the wheel hub membrane, still can produce the pressing motion of gradually pressing the wheel hub membrane. The pressing motion corresponds to the lifting motion of the link 230. When the first film scraping part 210 and the second film scraping part 220 sweep paths with the same length on the hub film, the rotation angle of the connecting piece 230 is smaller, so that the failure rate of the connecting piece 230 after being used for a long time is lower, and the whole occupied space of the film scraping assembly is smaller. In other words, when the membrane body 310 and the release paper 320 of the hub membrane 300 need to be separated by the same area (the area of the separation is proportional to the size of the path swept by the first membrane scraping portion 210 and the second membrane scraping portion 220 on the hub membrane 300), the connecting member 230 only needs to rotate by a smaller angle to achieve the same effect compared to the scheme in which the first membrane scraping portion 210 and the second membrane scraping portion 220 are cylindrical and the rotation axis is located at the center. This results in a lower failure rate and less wear of the connection member 230 after prolonged use, and a smaller overall footprint for the detachment mechanism 200.
