Abstract
A ball head turnable trailer is provided, including a trailer body and a trailer assembly containing a connecting component and a trailer component. The trailer component includes a mounting base and multiple ball heads. A rotating adjustment assembly includes a pin sleeve, a fixed pin, and a reset spring. A rotating shaft is roundly set with multiple fixed holes, each of which is matched with the fixed pin. A pull portion is pulled outwards to drive the fixed pin to move out from the fixed hole to release position limiting between the mounting base and the rotating shaft. The trailer no longer needs remove the fixed pin, which prevents the fixed pin losing. Moreover, the trailer is simple and labor-saving to pull, which is convenient and efficient.
