[0021] It should be noted that the user can control the elastic mechanism 8 to make the steel ball 7 inside the ball groove 6 fix the fixing sleeve 2, thereby achieving the purpose of quickly installing or disassembling the solar tube 1, realizing the function of facilitating the user to quickly install or disassemble the solar tube 1, and the installation is relatively stable and not easy to loosen and fall off, solving the problem that the current solar vacuum tube has improved the extreme thermal efficiency of the solar vacuum tube, but it does not have the function of quickly installing or disassembling the solar tube 1 and has poor practicality.

[0022] In a further preferred embodiment of the present invention, Figure 2 As shown, the elastic mechanism 8 includes: a mounting sleeve 3 is slidably connected with a lifting ring 9 near the steel ball 7, a connecting ring 10 is fixedly connected to the outer surface of the lifting ring 9, and a force ring 11 is fixedly connected to the outer surface of the connecting ring 10; a movable groove 12 is provided on the inner wall of the lifting ring 9, and a clamping groove 13 is provided on the fixing sleeve 2 near the steel ball 7, and both the movable groove 12 and the clamping groove 13 are adapted to the steel ball 7.
