However, the early umbrellas needed to push the umbrella frame up to a certain position by hand to open the umbrella. Once the sudden rain fell, it was often too late to open the umbrella and it was already wet.

Therefore, someone has designed a kind of umbrella, is provided with button at the handle, presses this button and can automatically open umbrella, but does not have the function of automatically closing umbrella, still needs both hands to fold back with umbrella when desiring to take a car In order to enter the car, in this short period of time, it will be wet by rain

[0003] In addition, there is only one pull cord for the existing automatic umbrella, which bears the pulling force of opening and closing the umbrella, and is easily broken, and after being stretched, the center stick of the umbrella will shake and become unstable, which will affect the stability of the umbrella. strength and service life
