[0021] A lifting bracket is fixedly connected to one side of the support platform 2, and a positioning cylinder 10 is fixedly connected to one side of the lifting bracket. The lifting bracket includes a support plate fixedly connected to one side of the support platform 2. Lifting cylinders 8 are fixedly connected to both ends of the support plate. Connecting blocks are fixedly connected to the upper ends of the lifting cylinders 8. A positioning plate 9 is fixedly connected between the connecting blocks on both sides. The positioning cylinder 10 is fixedly connected to one side of the positioning plate 9. Multiple gears 12 arranged in a circular array are rotatably connected to the inner wall of the positioning cylinder 10. Fixed swing arms 13 are fixedly connected to one side of each gear 12. The positioning cylinder 10 is provided with a strip hole 11 that cooperates with the fixed swing arm 13. The fixed swing arm 13 is slidably connected to the strip hole 11. A second adjustment mechanism for driving the gears 12 to rotate is provided inside the positioning cylinder 10. The second adjustment mechanism includes a second adjustment cylinder 14 fixedly connected to the positioning cylinder 10. A connecting column 15 is fixedly connected to one end of the second adjustment cylinder 14. A rack 16 that meshes with the gears 12 is fixedly connected to the outer wall of the connecting column 15.

[0022] In practical use, the pipe is placed between the two positioning cylinders 10. The motor 20 is started to drive the bidirectional screw 19 to rotate. The bidirectional screw 19 drives the sliders 17 and sliding holes 18 on both sides to move closer together, so that the support platforms 2 on both sides move closer together. At the same time, the positioning cylinders 10 on both sides are inserted into the pipe.
