[0023] Specifically, when fixing the spliced ​​steel pipe body 1, turn the handle 6 clockwise, which will drive the second gear 7 to rotate, and the second gear 7 will drive the double-sided gear ring 5 to rotate and drive the first gear 3 to rotate counterclockwise, at which time the threaded rod 4 will be tightened inward and drive the block 13 to be stuck into the hole 10. After it is fixed in place, stop rotating the handle 6, and the block 13 will be completely stuck into the mounting frame 2, and the splicing work is completed.

[0024] Reference Figure 1 and Figure 3 The top of the outer wall of the steel pipe body 1 is fixedly connected to a motor 9, the driving end of the motor 9 penetrates the outer wall of the steel pipe body 1 and is fixedly connected to a second roller 18, the bottom of the second roller 18 is fixedly connected to a first bevel gear 14, the left end of the outer edge of the first bevel gear 14 is meshed with a second bevel gear 17, the inner wall of the second bevel gear 17 is fixedly connected to a first roller 16, a plurality of blades 15 are fixedly connected to the four sides of the outer wall of the left end of the first roller 16, and the right end of the first roller 16 is rotatably connected to a fixed plate 19, and the upper and lower ends of the fixed plate 19 are fixedly connected to the inner wall of the steel pipe body 1

[0025] Specifically, there is a heating wire inside the blade 15 and the blade has a certain angle 15. When the auxiliary pipeline transports oil, the motor 9 is turned on, and the driving end of the motor 9 will drive the second roller 18 and the first bevel gear 14 to rotate.
