Currently, in the process of transporting a vehicle by using a transport tool, the vehicle is mainly fixed by manually using a special fixing mode, and the main method is to fix the wheel by using a wheel fixer and a binding band (or a clamping device). The wheel fixer mainly prevents the front and back movement of the wheel, and the binding band prevents the left and right up and down movement of the wheel. Its advantage is: simple structure and low cost. The disadvantages are as follows: the manual operation is needed to be completed, the automation cannot be realized, and the labor intensity of the manual operation under the condition of batch transportation is high. At present, the requirement on the transportation efficiency of a vehicle is higher and higher, and a set of reliable automatic automobile fixing device is designed, can realize automatic fixing of the vehicle, and reduces the labor cost.
