“用下巴夹住”可以表达为 “hold something with one's chin” 或 “clamp something between one's chin and [the relevant body part, often omitted if context is clear]” 。不过在日常表达中，更简洁自然的说法是 “hold something under one's chin” （将某物置于下巴下方夹住） ，或者根据具体情境描述动作，比如 “He managed to hold the phone between his chin and shoulder”（他用下巴和肩膀夹住了电话） 。
