[0002] Now that China has entered an aging society, products for the elderly are emerging like mushrooms after rain, such as shopping carts for seniors. However, the shopping carts currently on the market are not convenient to carry, and after use, they are too big to put anywhere. Another Chinese patent of the applicant, 202420991480.1, discloses "A Portable Shopping Cart Bag", authorized publication number CN222005120U. This patent includes a cart board, movable wheels installed on the lower part of the cart board, a tension rod set on the upper part of the cart board, and a storage bag. The movable wheels are installed on the front end of the cart board through a hinge assembly. Two movable wheels are symmetrically arranged. A V-shaped groove is opened in the middle of the cart board along the length direction. The left and right ends of the V-shaped groove are rotatably connected to the support legs through fixed sleeves. A U-shaped groove is connected to the rear end of the V-shaped groove. A protective sleeve top support is inserted into the U-shaped groove. The protective sleeve top support is sleeved on the lower part of the tension rod. A connecting shaft passes through the tension rod, the protective sleeve top support, and the U-shaped groove to fix the tension rod and the protective sleeve top support relatively and rotatably connect them to the U-shaped groove. Several buckles are installed vertically at equal intervals on the back side of the storage bag. The storage bag is tied to the tension rod by the buckles. While this shopping cart can be folded up and unfolded, solving the problems of easy carrying and storage without taking up space, the operation of folding up and unfolding the shopping cart is rather cumbersome. In particular, it requires multiple steps to unfold and fold up the shopping cart, which cannot be unfolded and used quickly, wasting a lot of time and being inconvenient to use.
