[0008] Furthermore, a second drive motor is fixedly mounted on the top of the main frame, and an output end of the second drive motor is fixedly connected to a driving bevel gear.

[0009] Furthermore, two second threaded rods are rotatably connected inside the main frame, and two clamping plates are connected on the surfaces of the second threaded rods via threads.

[0012] Furthermore, the top end of the main frame is fixedly connected with four fixing holes.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model is capable of driving the first threaded rod to rotate by setting a first driving motor, so that the sliding clamp can move and the connecting rod can cooperate with the connecting hole. Before that, the fixed clamp and the sliding clamp will wrap the connecting port on the top of the container, so that the connecting rod passes through the connecting port, connects the main frame with the container, and prevents the container from falling off during transportation.

[0015] 2. The second driving motor can drive the active bevel gear to rotate, and the cooperation between the active bevel gear and the driven bevel gear can cause the two second threaded rods to rotate, so that the two clamping plates move in opposite directions, thereby further fixing the container to prevent the container from falling off during transportation.
