The invention relates to the technical field of transferring device equipment, in particular to an efficient pipe fitting perforating device. A rack is included; a plurality of positioning mechanismsare arranged in a fixed frame and each comprise a positioning ring; the front and rear ends and the left and right ends of each positioning ring are fixedly connected with a longitudinal connection plate and a transverse connection plate correspondingly; the upper and lower planes of the transverse connection plate at the right end of each positioning ring are fixedly connected with a supporting plate forming a 45-degree included angle with the transverse connection plate; second hydraulic cylinders are fixedly connected to the supporting plates; the inner wall of each positioning ring is provided with two limiting holes corresponding to the positions of the two corresponding second hydraulic cylinders, and piston rods of the second hydraulic cylinders are inserted into the limiting holesin a sliding manner and are fixedly connected with limiting blocks; every two adjacent positioning rings are fixedly connected with the same transverse connection plate or longitudinal connection plate; the transverse connection plates and the longitudinal connection plates close to the inner wall of the fixed frame are fixedly connected with the inner wall of the fixed frame; and the right end ofthe rack is fixedly connected with a plurality of plastic buckets. The efficient pipe fitting perforating device has the advantages of being convenient to use, high in perforating efficiency, accurate in perforating and the like.
