A travel suitcase refers to a travel tool with the function of loading, carrying and storing clothes, which is made of various leathers, artificial leathers, synthetic leathers, plastics, textiles as the fabric and plywood, plastic plates, cardboard as the inner tire, and is manufactured by hot pressing, vacuum forming, injection molding, sewing processes. When the existing travel suitcases are carried, the presence of rollers can improve the carrying convenience. The existing roller structures are mostly fixed structures, so it is impossible to control the fixed placement of the travel suitcase. Based on this, it is necessary to provide a travel suitcase with rollers having a retraction performance to improve the placement convenience. In addition, the stability of the existing travel suitcases during placement is weak, and there is a possibility of tipping over. Based on this, it is necessary to provide a travel suitcase that can improve the anti-stability and enhance the practicability. Summary of the Utility Model
