    摘要: The disclosure provides an operating rod assembly and a string trimmer. The operating rod assembly includes a first rod provided with a first limiting piece, a second rod provided with a second limiting piece and a connector for connecting the first rod and the second rod. An outer diameter of the second rod is smaller than an inner diameter of the first rod; the first limiting piece and the second limiting piece are matched to limit the relative rotation angle between the first rod and the second rod. When the connector is in a locking state, two ends of the connector respectively lock the first rod and the second rod; when the connector is in a loosening state, the connector releases the second rod or the first rod, and the first rod and the second rod can rotate and stretch relative to each other.
