In a conventional umbrella, the opening and closing of the umbrella is usually locked by installing two repels. However, in such two repelling structures, it is necessary to install two repelling grooves on the middle rod, so the strength of the entire repelling will be destroyed and it will be necessary to push the lokuro directly. When the user opens and closes the umbrella, the stroke that is manually operated is relatively long, and the two repels are exposed from the side wall of the center rod, which may injure people.

In order to overcome the problems in the prior art, the present invention provides a quick and labor saving umbrella opening and closing device.
