Problems solved by technology

[0003] There are many problems in the stretching process of shoes. For example, some existing stretching devices are mostly fixed structures, and the scope of use is limited. It is necessary to match different types of stretching devices for shoes that cannot be used. The operation is more complicated. When the device is used, it cannot effectively remove the peculiar smell in the shoes, and at the same time, it cannot effectively deal with the moisture in the shoes, which reduces the comfort of the user and is not easy to use.
