[0042] The socket 11 and the connecting body are used to position the first tube body 1 and the second tube body 2 to prevent the first tube body 1 from being misaligned with the second tube body 2. In order to prevent the first tube body 1 from rotating relative to the second tube body 2, a groove body can be set in the socket 11, and a column body that cooperates with the groove body can be set on the insert 21. Both the column body and the groove body are set along the axial direction of the first tube body 1.

[0043] A connector 3 is disposed between the first tube body 1 and the second tube body 2, and both the first tube body 1 and the second tube body 2 are provided with a positioning groove 31 that cooperates with the connector 3;

[0044] The splicer 3 includes an upper seat 32 and a lower seat 33 fixed to the upper seat 32. Both the upper seat 32 and the lower seat 33 are provided with a positioning ridge 34 that cooperates with the positioning groove 31. A part of the positioning ridge 34 is located in the positioning groove 31.

[0045] The lower seat 33 is provided with a positioning piece 331 extending to the upper seat 32 , and both the positioning piece 331 and the upper seat 32 are provided with a pin hole 35 ; the positioning piece 331 is staggered with the positioning edge 34 located on the upper seat 32 to prevent the positioning piece 331 from interfering with the positioning edge 34 located on the upper seat 32 .

[0046] The splicer 3 further includes a pin shaft 36 matched with the pin hole 35 , and the pin shaft 36 is further provided with a locking pin 37 to prevent the pin shaft 36 from being separated from the pin hole 35 .

[0047] Reference Figures 1 to 6As shown, in some embodiments, the first tube body 1 is provided with a first ring edge 12, the first ring edge 12 and the first tube body 1 are an integral structure, there are at least two first ring edges 12, and a positioning groove 31 located in the first tube body 1 is formed between two adjacent first ring edges 12.

[0048] The second tube body 2 is provided with a second ring edge 22 . The second ring edge 22 and the second tube body 2 are an integral structure. There are at least two second ring edges 22 , and a positioning groove 31 located in the second tube body 2 is formed between two adjacent second ring edges 22 .

[0049] The positioning piece 331 can contact the first ring edge 12 and the second ring edge 22, so that the positioning piece 331 not only connects the upper seat 32 and the lower seat 33, but also has the function of the positioning edge 34, so that the first tube body 1 and the second tube body 2 have higher position accuracy.

[0050] During the construction process, the insert 21 is first inserted into the socket 11. At this time, the first tube body 1 is docked with the second tube body 2.

[0059] In some embodiments, the positioning plate 331 and the lower seat 33 are an integrated structure, and there are two groups of positioning plates 331. The positioning edges 34 located on the upper seat 32 are located between the two groups of positioning plates 331. Each group of positioning plates 331 has two plates and are respectively located on both sides of the first tube body 1 or the second tube body 2.

[0060] The positioning piece 331 is staggered with the positioning edge 34 located on the upper seat 32 .

[0061] Reference Figures 1 to 6 As shown, in some embodiments, a limit head 361 is provided at one end of the pin shaft 36, the diameter of the limit head 361 is larger than the diameter of the pin hole 35, the limit head 361 and the pin shaft 36 are an integrated structure, and an installation hole for installing the locking pin 37 is provided at one end of the pin shaft 36 away from the limit head 361.
