[0003] At present, there are generally two sets of suitcase trolleys, which are fixed at the bottom of the suitcase respectively. On the one hand, this design is not neat. Secondly, since it is fixed separately, there is no connecting and fixing part in the middle, which is easy to shake after long-term use. At the same time, the handle part of the current suitcase trolley is unreasonably designed. The handle is generally an integral design and is directly connected and fixed to the trolley. The connection part is not stable and the physical strength is not high enough. It is easy to loosen and fall off after a period of use. Furthermore, the handle part lacks perspiration function, and sweat is easily generated when used in summer, resulting in a poor user experience. There are certain defects and shortcomings, and therefore, improvements are needed. Utility Model Content
