Problems solved by technology

[0006] When the existing umbrella composed of the above-mentioned structure is opened and used, when the umbrella is overturned due to a sudden strong wind, the rib pole or the middle part of the rib will be damaged, and it is actually difficult to repair such a damaged umbrella. bone pole or umbrella rib, and even if the damaged umbrella can be repaired, the difference between the maintenance cost and the cost of purchasing a new umbrella will not be large, so the user buys a new umbrella and discards the damaged umbrella, resulting in waste problems caused by resources
