Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

The first expansion groove 31, the second expansion groove 33 and the third expansion groove 35 have the same size, the first expansion head 4 and the second expansion head 42 have the same size as the first expansion groove 31, and the inner diameters of the first through hole 3, the second through hole 34 and the third through hole 36 are all larger than the inner diameter of the penetration hole 32.

[0024] The effect achieved by the entire embodiment 1 is that the insulation shell 1 in the device is 3 cm, wherein the penetration hole 32 is 0.3 cm, and the thickness of the insulation shell 1 can also be increased to 5 cm or 8 cm as needed, and the corresponding height of the penetration hole 32 needs to be designed to be 2.3 cm and 5.3 cm. When the thickness of the insulation board does not match the requirements of some structures during construction and a large number of thicker insulation boards need to be replaced, the two insulation shells 1 can be stacked and aligned up and down, and then a thin iron wire is used to pass through the first through hole 3, the first expansion groove 31 and the penetration hole 32, and then the first expansion head 4 is squeezed downward, and then the first expansion head 4 is squeezed from the second expansion groove 33 to the inside of the third expansion groove 35, and the first expansion head 4 is squeezed into the third expansion groove 35.
