[0035] Referring to Figure 1 and Figure 4The connecting assembly comprises a magnet 5 made of a neodymium-iron-boron permanent magnet material with high magnetic strength and good stability, the outer wall of which is fixed tightly inside the pipe clamp two 6 by a special gluing process, and is also fixed inside the pipe clamp one 4 in the same way. The gluing material has the characteristics of high temperature resistance and aging resistance, and can ensure that the magnet 5 is firmly attached to the pipe clamp in the complex working environment of the coal saving device for a long time, providing reliable suction force for the connection between the pipe clamps. The outer wall of the magnet 5 is fixedly connected inside the pipe clamp two 6, and the outer wall of the magnet 5 is fixedly connected inside the pipe clamp one 4. The pipe clamp one 4 is fixedly connected with a connecting shell one 7 at the top and the bottom, the connecting shell one 7 is made of high-strength aluminum alloy material through precise die casting process, which not only ensures the strength of the shell, but also reduces the overall weight. The connecting shell one 7 is provided with a moving groove 14 and a clamping groove 15 inside. The pipe clamp two 6 is fixedly connected with a connecting shell two 8 at the top and the bottom, the connecting shell two 8 is also made of aluminum alloy material and is processed by a numerical control machining center to ensure the dimensional accuracy of each part. The connecting shell two 8 is provided with a limiting groove 17 inside, and the connecting shell two 8 is slidably connected with a rotating knob 19 inside.

[0036] Specifically, in the operation of fixing the straight pipe 1, when the pipe clamp one 4 and the pipe clamp two 6 begin to merge, the connecting shell one 7 and the connecting shell two 8 at the top and the bottom thereof are also close to each other, at this time, the knob 19 can be pressed, the knob 19 drives the fixed column 21 to move, the movement of the fixed column 21 promotes the sliding of the clamping column 16 in the moving groove 14. At the same time, the knob 19 also drives the fixed disc 20 to move in the limiting groove 17, which compresses the spring two 18. After the above steps are completed, the knob 19 is rotated, the knob 19 drives the fixed column 21 to rotate, and then drives the clamping column 16 to rotate, so that the clamping column 16 is aligned with the clamping groove 15, then the knob 19 is loosened, under the action of the spring two 18, the knob 19 returns to the original position, and drives the clamping column 16 to slide into the clamping groove 15.

[0037] Working principle: when fixing the straight pipe 1, the straight pipe 1 is clamped on both sides by the pipe clamp one 4 and the pipe clamp two 6, when the pipe clamp moves, it drives the clamp 9 to move and cover the outer wall of the straight pipe 1, then the pipe clamp one 4 and the pipe clamp two 6 are merged, so that the clamp 9 is pushed by the straight pipe 1, so that the slide column 10 is driven by the clamp 9 to move, then the limiting disc 11 is driven by the slide column 10 to move in the limiting groove 12, and the spring one 13 is compressed, then the spring one 13 rebounds to drive the clamp 9 to exert pressure on the straight pipe 1, so as to fix it. At the same time, when the pipe clamp one 4 and the pipe clamp two 6 are merged, the connecting shell one 7 and the connecting shell two 8 at the top and the bottom thereof are aligned, the knob 19 can be pressed, the knob 19 drives the fixed column 21 to move, so as to drive the clamping column 16 to slide in the moving groove 14. At the same time, the knob 19 also drives the fixed disc 20 to move in the limiting groove 17, which compresses the spring two 18. After the above steps are completed, the knob 19 is rotated, the knob 19 drives the fixed column 21 to rotate, and then drives the clamping column 16 to rotate, so that the clamping column 16 is aligned with the clamping groove 15, then the knob 19 is loosened, through the spring two 18, the knob 19 returns to the original position, and drives the clamping column 16 to slide into the clamping groove 15. In this way, the connecting shell one 7 and the connecting shell two 8 are connected, so that the pipe clamp one 4 and the pipe clamp two 6 are connected. Subsequently, the pipe clamp can be connected to the required position by the magnet 5.
