Description

technical field [0001] The invention belongs to the field of umbrellas, in particular to an automatic opening and closing umbrella. Background technique [0002] Umbrellas are daily necessities, and umbrellas can be divided into folding umbrellas and straight umbrellas. Umbrellas that automatically open and close have appeared in today's life, and most of them are the design scheme of folding umbrellas. However, for large-scale parasols, straight umbrellas are usually used at present, because large-scale folding umbrellas have a complicated structure, high cost, and are difficult to mass-produce. Contents of the invention [0003] In order to solve the above technical problems, the object of the present invention is to provide a large umbrella with simple structure, convenient opening and closing, and high degree of automation. [0004] In order to achieve the above object, the technical solution of the present invention is as follows: an umbrella that can be opened and ...
