[0029] In actual use, by providing the first V-shaped plate 1, it is convenient to set it on the main pipe 16, so that the third V-shaped plate 10 can effectively support the branch pipe 17. By providing a clamping mechanism, it is convenient to limit the branch pipe 17 between the third V-shaped plate 10 and the fourth V-shaped plate 14, so that the position of the branch pipe 17 and the main pipe 16 is relatively fixed, which is convenient for subsequent welding work.
[0030] It should be noted that the sleeve 12 is provided with an internal thread adapted to the second screw rod 13 .
