[0002] Using a pickup truck or an SUV connected to a trailer to transport a small boat to the water for playing and fishing is a pleasant leisure activity. Generally, during the process of the small boat entering the water, the trailer needs to put the boat into the water from the slope by the water's edge. At this time, the wheels of the trailer also enter the water, resulting in the wheels getting rusty, which in turn affects the daily use. Subsequently, it needs to be maintained at a high price before it can be used again. Summary of the Utility Model
