Preferably, the bottom frame is connected with a lifting braid used for lifting and folding the bottom frame. The lifting and drawing of the mesh belt is convenient for the lifting, drawing and folding operation of the underframe.

Preferably, the chassis comprises a front chassis and a rear chassis which are rotatably connected together, the front chassis is rotatably mounted on the front frame, and the rear chassis is rotatably mounted on the rear frame. The front underframe and the rear underframe rotate upwards and are folded, and the connecting position of the front underframe and the rear underframe moves upwards, so that the folding is convenient and fast.

Preferably, the underframe is provided with a limiting strip, and the limiting strip is arranged on the front underframe and covers the rear underframe; or the limiting strip is arranged on the rear underframe and covers the front underframe.

After the underframe is unfolded downwards to the right position, the limiting strip plays a good limiting role, the underframe is prevented from further downwards rotating, and meanwhile, the stability of the cart is improved.

Preferably, the width of the front chassis is gradually reduced from the front to the back, and the width of the rear chassis is gradually reduced from the back to the front.

Preferably, the folding cart is provided with wheels and a push-pull rod, after the front frame and the rear frame are close to each other and folded in place, the lower ends of the side rods are higher than the lowest point of the wheels, and the height position of the folded upper end of the underframe is close to the height position of the upper end of the push-pull rod.

After the folding cart is completely folded, the wheels are the lowest points, the height position of the upper end of the folded chassis is the highest point, and the side rods are arranged between the highest position and the lowest position, so that the overall package of the cart is as small as possible.

Preferably, the lower end of the front frame is provided with a support and a positioning seat, the positioning seat is provided with a C-shaped clamping seat, the lower end of the push-pull rod is hinged on the support, and the push-pull rod can be clamped on the clamping seat. The support and the positioning seat facilitate the installation of the push-pull rod.
