The invention discloses a conveying device used for a needle type component treatment. The conveying device used for the needle type component treatment comprises a guiding rail and a fixture, whereinthe guiding rail comprises a first rail and a second rail which are horizontally arranged and a position difference exists between the first rail and the second rail in the vertical direction; the fixture comprises a supporting mechanism and a pressing mechanism, wherein the supporting mechanism and the pressing mechanism are arranged along the guiding rail in a sliding manner; the supporting mechanism and the pressing mechanism move simultaneously along the guiding rail in the horizontal direction; the supporting mechanism and the pressing mechanism are enabled to move in the manner of beingfar away from each other relatively in the vertical direction by one of the first rail and the second rail, and the supporting mechanism and the pressing mechanism are enabled to move in the manner of being close to each other relatively in the vertical direction by the other one of the first rail and the second rail. The device is capable of clamping needle type components for various treatmentsconveniently. The device is simple in structure and easy to implement.
