DETAILED DESCRIPTION OF THE EMBODIMENTS

[0013] In order to more clearly illustrate the technical solutions in the embodiments of the present utility model or the prior art, the following will briefly introduce the drawings required for use in the description of the embodiments or the prior art. Obviously, the following drawings are only some embodiments of the present utility model. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings.

[0014] Refer to as Figure 1 —— Figure 3As shown, this specific embodiment adopts the following technical scheme: it comprises a workbench 1, a pipe fixing perforation 2, a clamping cylinder 3, a clamping connecting plate 4, a large pipe clamping arm 5, a small pipe clamping arm 6 and a guide rod holding assembly 7; two clamping cylinders 3 and a guide rod holding assembly 7 are installed around the pipe fixing perforation 2 on the workbench 1, and the three are evenly distributed along the circumference, the clamping cylinder 3 is drivingly connected to the clamping connecting plate 4, and a large pipe clamping arm 5 is fixed on the clamping connecting plate 4, and the cross section of the large pipe clamping arm 5 is an arc-shaped structure, and a tongue and groove 8 is arranged on the arc-shaped cross section, and the small pipe clamping arm One end of 6 is provided with a tenon 9, and the small tube clamping arm 6 is connected to the large tube clamping arm 5 through the tenon 9 and the tenon groove 8. The other end of the small tube clamping arm 6 is in an arc shape. When clamping a large tube diameter of Φ140-Φ250, the small tube clamping arm 6 is removed, and the clamping connecting plate 4 is driven by the clamping cylinder 3 to drive the large tube clamping arm 5 to extend and retract toward the center of the tube fixed perforation 2; when clamping a small tube diameter of Φ40-Φ125, the small tube clamping arm 6 is installed, and the clamping connecting plate 4 is driven by the clamping cylinder 3 to drive the large tube clamping arm 5 and the small tube clamping arm 6 to extend and retract toward the center of the tube fixed perforation 2.
