Further, the limiting block is fixed on the side face of the V-shaped block through a bolt, and the limiting block is located at the 1/2 depth of the V-shaped opening. The limiting block is positioned at the 1/2 depth of the V-shaped opening and can block pipe parts with different diameters.

Further, be equipped with a plurality of screw holes on the base, V type piece passes through bolt and screw hole cooperation fixed connection on the base. The V-shaped blocks are arranged at different threaded holes on the base, so that the installation distance between the two symmetrically arranged V-shaped blocks is changed.

Further, the V-shaped opening side is additionally provided with an external tool capable of twisting the pipe part to rotate, the external tool is disc-shaped, one end of the external tool is provided with a convex positioning table, the periphery of the positioning table is provided with a plurality of contour lines, and two convex positioning shafts are arranged on the positioning table. The machine tooling has two reference holes on the pipe part terminal surface, and two convex locating shaft are installed respectively and are inserted in two reference holes of pipe part, just can take the pipe part to rotate in anchor clamps through rotating outside frock, are convenient for carry out inclined hole processing on the different positions on the pipe part terminal surface, and the contour line through the difference on the locating bench is parallel with the base to confirm the processing position of the different inclined holes of pipe part terminal surface, avoid causing the repeated processing of same position.
