The utility model relates to an elastic telescopic service life testing device for an arc-shaped piece, and the device comprises a workbench, a first clamp which is fixedly disposed at the top of the workbench, and is used for fixedly placing a head-wearing ring in which the arc-shaped piece can be movably inserted. The first driving source is fixedly arranged on the workbench and is used for providing testing power; and the second clamp is arranged on the first clamp in a swinging mode, and the first driving source can drive the second clamp to swing back and forth in a reciprocating mode. According to the utility model, the head ring of the whole earphone is fixed on the first clamp, the telescopic plate is elastically fixed on the second clamp for positioning, and then the second clamp is driven by the first driving source to simulate the elastic drawing of the telescopic plate to swing within a rated angle range, so that the service life of the elastic shape of the arc-shaped telescopic plate in the earph
