It can be understood that the above-mentioned scheme can be used in the scene of quick installation and disassembly of the fastening device, and can also be used to solve the problem of fixing the overall position of the device.

[0020] According to the present specific embodiment, the fixing ring 102 is slidably connected to the tube body 101 and is located on the outside of the tube body 101. The number of the supporting blocks 103 is two. The two supporting blocks 103 are respectively fixedly connected to the fixing ring 102 and are respectively located on the top of the fixing ring 102. The fastening bolt 104 is slidably connected to the supporting block 103 and passes through the supporting block 103. The limiting block 105 is threadedly connected to the fastening bolt 104 and is located on the outside of the supporting block 103. The mounting assembly is connected to the fixing ring 102, and the fixing ring 102 is used to fix the tube body 101.
