[0006] By adopting the above technical solution, the handle is hinged to the hinge shaft at the bottom of the frame, so that the handle can be placed under the frame for storage. When the carrying trolley is not in use, the handle is in a storage state to reduce the occupied space; by connecting a drawer to the frame, the carrying trolley has a storage function, which can store tools needed in the power battery assembly process, thereby improving the practicality of the carrying trolley.

[0007] In order to better solve the above technical defects, the utility model also has a better technical solution:

[0008] In some embodiments, two drawers are disposed between the two connecting rods of each group, and the two drawers are symmetrically disposed at both ends of the connecting rod and are respectively connected to the connecting rod through drawer rails.

[0009] In some embodiments, a rechargeable battery and a long warning light are installed on the frame, and the warning light is installed at the right end of the frame and is electrically connected to the rechargeable battery through a control switch. The warning light can be turned on or off by the control switch, and the turning on of the warning light can serve as a warning, thereby further improving the practicality of the load-bearing vehicle.

[0010] In some embodiments, the control switch is provided with two, one of which is fixedly connected to the lower left end of the frame, and the other is fixedly connected to the lower right end of the frame. Thus, the warning lights can be turned on at both ends of the load-bearing trolley.

[0011] In some embodiments, a buzzer is electrically connected to the circuit between the control switch and the warning light, so that a better warning effect can be achieved through the coordination of the warning light and the buzzer.

[0012] In some embodiments, a storage box with an open top is placed in the drawer. The storage box is used to store tools, and when multiple tools need to be used, the storage box can be directly taken out.

[0013] In some embodiments, a tension spring is provided on both sides of the drawer, one end of the tension spring is connected to the drawer, and the other end is connected to the connecting piece on the connecting rod. The tension spring can prevent the drawer from opening automatically due to inertia when the load-bearing trolley turns. BRIEF DESCRIPTION OF THE DRAWINGS
