[0037] Specifically, please refer to Figure 1 and Figure 2 , the support 1 includes a base plate 12 and a seat body 13. The bottom end of the seat body 13 is fixed to the base plate 12. The base plate 12 is used to contact and fix with the placement surface. The outer side of the support assembly 3 is rotatably mounted on the seat body 13. The outer side of the mounting ring 4 is fixed to the seat body 13 through the mounting bracket 42, so that the mounting ring 4 can stably maintain coaxial cooperation with the drive ring 2.

[0038] Furthermore, please refer to Figure 2 and Figure 3, a slot 14 is formed inside the seat body 13. The support assembly 3 includes an annular plate 31 and a groove 32. The inner side of the annular plate 31 is fixed to the driving ring 2 to provide rotational support for the driving ring 2 in the seat body 13 through the annular plate 31. The groove 32 is formed on the front and rear surfaces of the annular plate 31.

[0045] The bevel gear 524 is fixed to the bottom end of the support cylinder 521 , and the support cylinder 521 is meshed with the gear block 22 through the bevel gear 524 , so that when the ring body 21 rotates, the bevel gear 524 can be driven to rotate through the gear block 22 , thereby driving the support cylinder 521 to rotate.

[0046] Among them, the output component 53 includes a gear 531, a motor 532 and a mounting plate 533.

[0047] During implementation, first put the pipe 11 on the sticking rod 513, and then operate the motor 532 so that the sticking rod 513 assembly is close to the outer wall of the pipe 11. After the outer wall of the pipe 11 contacts the four sticking rods 513, the motor 532 can be turned off. Then, the two pipes 11 to be matched are respectively installed on the corresponding calibration devices, so that their matching ends can be quickly concentric through the calibration device, thereby improving the convenience of subsequent matching welding. The connecting piece 23 is a tooth plate or a tooth groove, so that the gear 531 can quickly apply force to the ring body 21 through the connecting piece 23, driving the ring body 21 to rotate.
