Specifically, thediameter adjustment ring 10 and theaxial adjustment bar 11 are made of a shape memory alloy having a shape memory function throughout the entire range, and the shape thereof changes with a change in temperature. The global shape memory function is a low-temperature phase shape which is the same in shape and opposite in orientation when heated and cooled, and is called a global memory effect.

As shown in FIG. 3, at normal temperature, thediameter adjusting ring 10 is curled and shrunk inwardly, and the diameter of the circumscribed circle is D1; as shown in fig. 5, when the control device 3 controls the temperature of thediameter adjusting ring 10 to rise, thediameter adjusting ring 10 is stretched outwards, and the diameter of the circumscribed circle thereof is increased to D2, so that the diameter of thetube sheet 9 is also increased; when the control device 3 controls the temperature of thediameter adjusting ring 10 to be lowered, the degree of inward curling of thediameter adjusting ring 10 is increased, and the diameter of the circumscribed circle thereof is reduced to D3, so that the diameter of thetube skin 9 is also reduced.

Similarly, when the control device 3 controls the temperature of theaxial adjusting strip 11 to rise, the length of theaxial adjusting strip 11 is increased, the length of thetube skin 9 is increased, and when the control device 3 controls the temperature of theaxial adjusting strip 11 to fall, the length of theaxial adjusting strip 11 is decreased, and the length of thetube skin 9 is decreased. In practical application, theaxial adjusting strip 11 and thediameter adjusting ring 10 can both be connected with a power supply, and the control device 3 can control the temperature of theaxial adjusting strip 11 and thediameter adjusting ring 10 by controlling the current magnitude.
