This umbrella-insertable suitcase accurately solves the pain point of "holding an umbrella in a hand box" when traveling in rainy days. It does not occupy the storage space in the box, does not affect the implementation of storage, and prevents the dripping of umbrellas from polluting clothes or articles in the box. It improves the convenience and safety of traveling in rainy days with a very simple structure, adapts to many scenes such as commuting and short-distance travel, and provides a practical design scheme for daily travel.
