Connected to the limiting groove 202; the sliding assembly 4 includes a slider 401, a fixed column 402, and a tooth block 403; the slider 401 is slidably connected to the first annular groove 5, the tooth block 403 is fixedly connected to one side of the slider 401, and the fixed column 402 is fixedly connected to the outer wall of the slider 401; the tooth block 403 is slidably connected to the second annular groove 6, and one side of the tooth block 403 protrudes from the inner side of the ring arm 101; the arc length of the tooth block 403 is set according to the distance between the outer wall of the pipe to be fixed and the end of the bolt 3 located in the initial position.

[0028] In this embodiment: first, the aligner is put on one end of the pipe, and then another pipe section is hoisted and inserted into the aligner, so that the bolts 3 at both ends are aligned with the outer walls of the two pipe sections respectively, and then the bevel gear 203 is rotated to move the bolts 3 inward, so that one end of the bolt 3 presses the outer wall of the pipe, so that the pipe is offset, so that the two pipe sections are aligned, and after the alignment is completed, welding is performed to fix;

[0029] After the welding and fixing is completed, the bolt 3 needs to be loosened. At this time, hold the tooth block 403 and slide the slider 401 along the first ring groove 5. The slider 401 will drive the fixing column 402 along the second ring groove 6. When the fixing column 402 passes through the bevel gear 203, it will mesh with the bevel gear 203, so that the bevel gear 203 rotates, and the bolt 3 is threadedly connected to the bevel gear 203.
