[0013] The present invention will be further described in detail below with reference to the accompanying drawings.

[0014] Example 1: refer to Figure 1-9 A folding pull shopping cart includes a base 1, with brackets 2 rotatably connected to both sides of the bottom of the base 1, wheels 3 rotatably connected to one side of the brackets 2, support members 4 rotatably connected to both sides of the back of the base 1, a first pull rod 5 fixedly connected to the top of the support member 4, a first handle 6 fixedly connected to the top of the first pull rod 5, a connector 7 slidably sleeved on the surface of the first pull rod 5, a second pull rod 8 fixedly connected to the top of the connector 7, a second handle 9 fixedly connected to the top of the second pull rod 8, first locking blocks 10 integrally machined on both sides of the bottom of the base 1, a cloth bag 11 provided on the top of the base 1, an inner lining plate 12 provided inside the cloth bag 11, an insert 13 integrally machined at the bottom of the inner lining plate 12, the bottom of the insert 13 penetrating the cloth bag 11 and locking it to the base 1, a round hole 14 integrally machined inside the base 1 to match the insert 13, an inner lining strip 15 provided inside the cloth bag 11, and the inner lining strip 15 being threadedly connected to the second pull rod 8 by bolts.

[0015] Specifically, the device can quickly unlock multiple locks and complete the synchronous folding of the vehicle body and the cloth bag 11 through simple pressing and rotating actions, significantly improving storage efficiency and user experience. At the same time, the cloth bag 11 adopts a detachable structural design. Through the cooperation of the insert block 13 and the round hole 14 and the bolt-connected inner lining strip 15, the cloth bag 11 can be easily disassembled and installed. This not only facilitates cleaning and replacement, but also allows the device to flexibly switch between two usage modes: with and without a bag. The overall structure of the device ensures both compactness and portability after folding, while also enhancing the product's functional versatility and practical value.

[0016] refer to Figure 2 and Figure 3 The back of the cloth bag 11 is sewn with a flap 16, the inside of the flap 16 is sewn with a sub-fabricated patch 17, and the front of the cloth bag 11 is sewn with a female-made patch 18. By setting the sub-fabricated patch 17 and the female-made patch 18 to be bonded together, the flap 16 can be effectively limited.

[0017] refer to Figure 6 and Figure 7 The top of the support member 4 is integrally machined with a deformable end 19, and the top of the deformable end 19 is provided with a slot 20. The bottom of the base 1 is integrally machined with a fixing block 21 that matches the slot 20. By deforming the slot 20 through the deformable end 19, the limitation on the fixing block 21 can be released. The bottom of the support member 4 is integrally machined with an arc-shaped end 22. By setting the arc-shaped end 22, when the device is unfolded, the support member 4 rotates and pushes the bracket 2 to rotate through the arc-shaped end 22, so that the bracket 2 is opened.

[0018] refer to Figure 7 and Figure 8 One side of the support member 4 is integrally machined with a limiting plate 23, and the bottom of the base 1 is integrally machined with a limiting groove 24 that is adapted to the limiting plate 23. By setting the limiting plate 23 and the limiting groove 24, the support member 4 can rotate to drive the limiting plate 23 into the interior of the limiting groove 24, so that the support member 4 can effectively reinforce and limit the bracket 2.

[0019] refer to Figure 9 The top of the connector 7 is integrally machined with a second locking block 25. The inside of the first handle 6 is rotatably connected with two connecting rods 26. The bottom of the first handle 6 is slidably fitted with a handle button 27. One end of the connecting rod 26 passes through the inside of the handle button 27. A spring 28 is fitted between the first handle 6 and the handle button 27. By setting the spring 28, it is easy to reset the handle button 27. When unfolded, pressing the handle button 27 drives one end of the connecting rod 26 to lift, so that the connecting rod 26 releases the second locking block 25 from its limit. When folded, the second locking block 25 is engaged with the connecting rod 26, and the connector 7 can be limited.

[0020] Brief description of usage: The user can place items in the cloth bag 11. After use, press the handle button 27 to lift one end of the connecting rod 26, so that the connecting rod 26 releases the limit on the second locking block 25. Then press the second handle 9 to drive the connecting piece 7 to slide on the surface of the first pulling rod 5 through the second pull rod 8, so that the bottom 7 of the connecting piece presses against the deformable end 19. The deformable end 19 releases the limit on the fixing block 21 through the slot 20. Rotate the base 1 in the opposite direction to drive the cloth bag 11 to fold towards the first pulling rod 5. At the same time, the bracket 2 drives the wheel 3 to rotate and fold towards the base 1, so that the first locking block 10 engages with the first pulling rod 5. The first pulling rod 5 limits the bracket 2, thus facilitating the folding and storage of the device. The user can pull the cloth bag 11 to drive the insert 13 out of the round hole 14 through the inner lining plate 12. Then, tighten the bolt to disassemble the inner lining strip 15 from the second pulling rod 8, which facilitates the disassembly of the cloth bag 11 and allows for easy switching between the two modes of having a bag and not having a bag.
