The first screw rod 601 and the second screw rod 603 of the U-shaped stud bolt 6 are respectively passed through the fixing through hole K101 and the adjusting fixing through hole and then are screwed with nuts C7 to further ensure that the first fixing column 1 and the second fixing column 4 are fixed to each other.

[0038] A first pipe clamping mechanism 2 and a second pipe clamping mechanism 5 are fixedly mounted on the first fixing column 1 and the second fixing column 4 , respectively. The second pipe clamping mechanism 5 has the same structure as the first pipe clamping mechanism 2 .

[0039] like Figure 7-Figure 9 As shown, the first pipe clamping mechanism 2 and the second pipe clamping mechanism 5 both include a rectangular tube 201 and a pipe clamping portion. The pipe clamping portion of the first pipe clamping mechanism 2 makes the clamped pipe parallel to the first fixed column 1, and the pipe clamping portion of the second pipe clamping mechanism 5 makes the clamped pipe parallel to the second fixed column 4.

[0040] The rectangular tube 201 of the first pipe clamping mechanism 2 and the second pipe clamping mechanism 5 are slidably connected to the first fixing column 1 and the second fixing column 4 respectively, and the rectangular tube 201 of the first pipe clamping mechanism 2 is fixedly connected to the first fixing column 1 through a fixing unit, and the rectangular tube 201 of the second pipe clamping mechanism 5 is fixedly connected to the second fixing column 4.
