The outer part of the inner pipe 1 is tightly clung to the inner pipe 1 and is wrapped with a first heat preservation layer 2, and the first heat preservation layer 2 can be made of rock wool or polyurethane and other conventional heat preservation materials. The outside of the first heat-preserving layer 2 is provided with a fixed pipe 3, and the fixed pipe is made of metal, such as stainless steel.

A clamping piece 4 is arranged between the first heat preservation layer 2 and the fixed pipe 3, the clamping piece 4 extends from one end of the inner pipe 1 to the other end, and the clamping piece 4 is made of metal, such as stainless steel. As shown in fig. 3, the clamping member 4 includes an outer rod 12 and an inner rod 13, a bottom rod 14 is disposed between the outer rod 12 and the inner rod 13, and the bottom rod 14 is attached to the cross section of the first heat-preserving layer 2 to further support the thickness of the first heat-preserving layer 2 and the fixed tube 3. Whereby the bottom rods 14 are two and are located at the two ends of the fixed pipe 3, respectively. The inner rod 13 is vertically fixed at one end of the bottom rod 14, and the inner rod 13 is in contact with the first heat-preserving layer 2; the outer rod 12 is vertically fixed to the other end of the bottom rod 14, and the outer rod 12 is in contact with the stationary pipe 3. The number of the clamping pieces 4 is four, the space between every two adjacent clamping pieces 4 is 90 degrees, and the four clamping pieces 4 clamp the first heat insulation layer 2 and the fixed pipe 3, which is equivalent to clamping the inner pipe 1.

The outside of solid pipe 3 is provided with second heat preservation 5, and the outside parcel of second heat preservation 5 has shell body 6. A space is left between the outer shell 6 and the fixed pipe 3, and the space can be reserved, so that the air in the space forms a second heat insulation layer 5. Or the space is filled with foam, and the foam is the second heat insulation layer 5. The foam has a loose structure and thermal insulation characteristics, and the foam has elasticity, so that fine adjustment of the relative position of the inner tube 1 in the outer shell 6 can be realized.
