[0002] A folding cart is a transport vehicle that is pushed and pulled by manpower. Although the material handling technology of folding carts continues to develop, folding carts are still used as indispensable transport tools. Folding carts are widely used in production and life because they are low in cost, simple to maintain, easy to operate, and light in weight. They can work in places where motor vehicles are inconvenient to use and are very convenient for transporting lighter items over short distances. Most of the existing folding carts include a base plate and two fixing rods connected to the base plate. The folding effect is achieved by rotating the fixing rods to contact the base plate, which is mainly convenient for storage.

[0003] When a large round vase needs to be transported on a folding cart, the vase is usually placed manually at the center of the bottom plate. Since most existing folding carts do not have a device to fix the vase, the folding cart will rock left and right when transporting on bumpy roads, causing the vase on the bottom plate of the folding cart to rock on the bottom plate, resulting in the vase slipping and breaking.

[0026] In this embodiment, when in use, the bottom plate 2 is connected to the two fixing rods 1 through two sets of connecting components 3. The two fixing rods 1 and the bottom plate 2 are in a vertical state. When a large round vase needs to be transported by the equipment, the bottom of the bottom plate 2 is tilted and in contact with the ground, which makes it convenient for the staff to place the vase at the center of the top of the bottom plate 2. At this time, the staff drives the clamping component 6 to move through the moving component 5, and clamps and fixes the flowers on both sides of the bottom plate 2 through the clamping component 6 to prevent the vase from being transported on a bumpy road due to the uneven road. The vases on the bottom plate 2 shake on the bottom plate 2, causing them to slip and break. The two fixing rods 1 are pushed manually, and the bottom plate 2 and the vases fixed on the bottom plate 2 are moved by the moving wheels 7. When transported to the designated place, the bottom of the bottom plate 2 is tilted and contacts the ground, and the clamping assembly 6 no longer clamps and fixes the vases, so that they can be unloaded manually. When not in use, the two fixing rods 1 and the bottom plate 2 can be folded together through the connecting assembly 3, and the fixing rod 1 rotates, and drives the supporting assembly 4, the moving assembly 5 and the clamping assembly 6 to rotate synchronously, which is convenient for the staff to store.

At this time, the two fixing rods 1 and the bottom plate 2 are in a vertical state. When the two fixing rods 1 and the bottom plate 2 need to be folded together, the staff pulls the baffle 308, and the baffle 308 drives the connecting rod 304 to move synchronously. At the same time, the spring 307 is stretched by the baffle 308. At this time, the connecting rod 304 enters the fixing hole 305 in the second fixing plate 302 and is moved from the fixing hole 305 in the second fixing plate 302 to the fixing rod 1. The fixing rod 1 enters the fixing hole 305 in the first fixing plate 301. At this time, the fixing rod 1 will no longer fix the fixing rod 1. The staff rotates the two fixing rods 1 toward the bottom plate 2. The fixing rod 1 rotates along the rotating rod 303, so that the fixing rod 1 drives the connecting rod 304, spring 307 and baffle 308 that enter the fixing hole 305 on the first fixing plate 301 to rotate synchronously. At this time, the bottom plate 2 is in contact with the two fixing rods 1. The fixing rod 1 no longer blocks the two fixing holes 305. At this time, the staff no longer pulls the baffle 308, and the spring 307 drives the baffle 308 into When the cam 308 is in use, the staff pulls the baffle 308, the baffle 308 drives the connecting rod 304 to move synchronously, and the spring 307 is stretched through the baffle 308, and the connecting rod 304 comes out of the fixing hole 305 of the second fixing plate 302 and enters the first fixing plate 302. 01, at this time the connecting rod 304 no longer resists the fixing rod 1, and the staff rotates the two fixing rods 1, and the two fixing rods 1 are away from the bottom plate 2.
