The invention discloses a positioning carrier. The positioning carrier comprises a carrier middle frame, a carrier lower cover, a carrier upper cover, a plurality of clamping jaws, a center wedge block and a push rod. The carrier lower cover is fastened to the bottom end portion of the carrier middle frame, and a fixing base is formed on the carrier lower cover. The carrier upper cover is fastenedto the top end portion of the carrier middle frame. A containing platform is arranged on the top end face of the carrier upper cover. The clamping jaws are arranged in an annular area through first pin shafts in a sliding manner, wherein the annular area is defined by the fixing base and the inner wall of the carrier middle frame, the clamping jaws penetrate the carrier upper cover, and jaw headsof the clamping jaws surround the periphery of the containing platform. The center wedge block is located in the carrier middle frame and located below the clamping jaws. The push rod penetrates thecarrier middle frame and is located under the center wedge block. According to the positioning carrier, the purpose that the peripheral clamping jaws conduct clamping at the same time can be achievedthrough single actions, the production efficiency is effectively improved, and operation is convenient.
