ABSTRACT:
A coupling structure of the upper notch and the ferrule on an umbrella or parasol is provided to improve upon the habitually used screw type. With a newly designed ring, the coupling of the ferrule with the upper notch can be easily accomplished by pressing once. This saves effort and time. Once they are coupled, they will not become loose, thus preventing the ferrule from falling-off. If the umbrella falls to the ground due to carelessness, the ferrule and upper notch are not easily damaged or broken.
