[0001] The utility model relates to the technical field of trolleys, in particular to a trolley with adjustable width. Background Art

[0002] In logistics transportation, warehousing management, and daily handling work, trolleys, as a common tool, are widely used in the transportation of various items. However, traditional trolleys usually have a fixed width and load space, making it difficult to adapt to the needs of goods with different sizes and shapes. This fixed-width design is not flexible enough in some special cases, especially when passing through narrow channels or transporting items with irregular volumes, which limits the scope of application of the trolley.

[0003] To solve this problem, some trolley designs with adjustable width have emerged on the market. These trolleys introduce telescopic structures, enabling users to freely adjust the width of the trolley according to actual needs, thereby enhancing its adaptability. Such designs not only improve the versatility of the trolley in different scenarios but also effectively improve logistics efficiency and reduce the operation difficulty in narrow spaces.

[0004] However, the existing trolleys with adjustable width still have some deficiencies in design. For example, the width adjustment structure of some trolleys is relatively complex, inconvenient to operate, and prone to structural instability during the adjustment process. In addition, the load space of the trolley is usually fixed and cannot be effectively adjusted according to the size of the goods, resulting in low space utilization when transporting small or irregular items.

[0005] Therefore, it is very necessary to invent a trolley with adjustable width. Summary of the Utility Model
