A second groove 4 is arranged on the correction module 3. The correction arm 2 is arranged on the inner wall of the correction box 1. One end of the correction arm 2 is rotatably connected to the correction box 1. An opening 5 for the other end of the correction arm 2 to pass through the correction box 1 is arranged on the correction box 1. A first groove 6 is arranged on the correction arm 2. The second groove 4 and the first groove 6 enclose a pipe groove. A pipe hole 7 communicating with the pipe groove is arranged on the inner wall of the correction box 1. A pipe barrel 8 for inserting one end of the connecting pipe is arranged on one side of the correction box 1 with the opening 5. The pipe barrel 8 can telescopically move along the vertical direction. The other end of the connecting pipe is inserted into the correction box 1 through the pipe hole 7. When the second groove 4 and the first groove 6 are buckled, the connecting pipe located in the pipe groove is completed for correction.
[0025] The correction module 3 includes a correction mold 31 and an installation groove 32. The second groove 4 is arranged on the correction mold 31. The installation groove 32 is arranged on the correction mold 31. A fixing block 9 is arranged at the bottom of the correction box 1, and the fixing block 9 is inserted into the installation groove 32.
[0026] One end of the correction mold 31 facing the first groove 6 is provided with an inclined surface 10, and the second groove 4 is arranged on the inclined surface 10. The inclined surface 10 forms an angle with the side wall of the correction mold 31.
[0027] A reinforcing rod 11 is arranged on the side wall of the correction box 1, and a reinforcing groove 12 for inserting the reinforcing rod 11 is arranged on the side wall of the correction mold 31.
[0028] One end of the correction arm 2 is provided with an installation ring 13. An installation rod 14 is arranged on the inner wall of the correction box 1.
