Description

technical field [0001] The invention relates to the field of umbrellas, in particular to a telescopic umbrella automatic opening and closing structure and an automatic telescopic umbrella. Background technique [0002] An umbrella is a tool for shading or sheltering from rain and snow. Umbrellas need both hands to operate when opening and closing, which is very inconvenient to use. Therefore, people have developed an umbrella that can be opened and closed automatically. The existing automatic open and close umbrella mainly drives the umbrella rod to automatically expand and contract through the screw structure or the flexible rack. The pole is stuck, making the umbrella pole lifting very unstable. The umbrella opened and closed through the flexible rack, because the flexible rack is relatively soft, the flexible rack is easy to bend when the umbrella rod is extended, so that the flexible rack loses its supporting force instantly, which will easily lead to damage to the rac...
