I can only see the value of ControlType by UI Spy, currently. I have temporarily solved this problem using the following method.

from pywinauto.application import Application
import time

self.app = Application().start(path)
self.app = Application(backend='uia').connect(path=path)
web_element = self.app.XX系统.window(class_name='AfxFrameOrView100').window(
            class_name='Shell').element_info
parent_window = self.app.window(handle=web_element.handle)
edit = parent_window.child_window(control_type="Edit")
time.sleep(1)
edit.type_keys("test")
