The mounting assembly 1 also includes a fixed Velcro 104 and a Velcro pressing block 105, and the outer side of the second mounting side ring 103 is fixedly installed with the fixed Velcro 104 through the Velcro pressing block 105;

[0024] The first mounting side ring 102 and the second mounting side ring 103 are connected by the fixed Velcro 104 fixed by the Velcro pressure block 105, so that the entire device can be installed on the arm. The first mounting side ring 102 and the second mounting side ring 103 are opened through the rotating structure between the first mounting side ring 102 and the upper mounting ring 101 and the rotating structure between the second mounting side ring 103 and the upper mounting ring 101.
