[0037] Working principle: When laying the insulation pipe, the left end of pipe 1 can be inserted into the inside of pipe 2 2, and then the movable sleeve 9 is rotated to move the movable sleeve 9 toward pipe 2 2. During the movement of the movable sleeve 9, multiple movable blocks 7 can be pushed to move toward pipe 1. Multiple movable blocks 7 are inserted into the inside of pipe 1 to fix pipe 1 inside pipe 2 2, thereby completing the rapid splicing of pipe 1 and pipe 2 2.

[0038] After the splicing of pipe 1 and pipe 2 2 is completed, the protective shell 1 5 and the protective shell 2 6 are placed outside the connection between pipe 1 and pipe 2 2, and then multiple connecting plates 14 are inserted into the protective shell 2 6 to connect the protective shell 1 5 and the protective shell 2 6 to each other. Then, the two adjacent blocks 17 are pushed toward each other so that the bottom of the block 17 can be inserted into the inside of the mounting block 1 3. When the block 17 is released, the block 17 can be pushed by the spring 16 to connect the mounting block 1 3 and the mounting block 2 4 to each other, thereby strengthening the connection between the protective shell 1 5 and the protective shell 2 6 so that the protective shell 1 5 and the protective shell 2 6 protect the connection between pipe 1 and pipe 2 2. After the installation of protective shell 1 5 and protective shell 2 6 is completed, the support rod 20 can support pipe 1 1 and pipe 2 2. When pipe 1 1 and pipe 2 2 shake, pipe 1 1 and pipe 2 2 can push the support rod 20 to rotate. The rotation of the support rod 20 can pull the tension spring 2 2 to extend. The extension of the tension spring 22 can absorb the shaking generated by pipe 1 1 and pipe 2 2, thereby enhancing the stability of the connection between pipe 1 and pipe 2 2.
