Therefore, when the first distance is not smaller than the second distance, the linkage mechanism can provide a certain amount of acting force for resisting the forward movement of the material vehicle, the stress of the fifth push rod cylinder c2 is greatly reduced, and the service life of the fifth push rod cylinder c2 is prolonged.
