Alternatively, the connecting assembly 10 may be integrated with the electronic device 50. Alternatively, the connection assembly 10 and the electronic device 50 may be mounted without the need for a wrench, screwdriver, or other mounting tool. Optionally, the connecting assembly 10 and the electronic device 50 may be installed and fixed before the product is transported or shipped, and then the connecting assembly 10 and the electronic device 50 do not need to be installed at an installation site. It will be appreciated that the electronic device 50 includes a working surface, which is a front surface, and a non-working surface, which may be a peripheral side or back surface 51, with the connection assembly 10 connected to the non-working surface. Optionally, the connection assembly 10 is connected to the rear face 51.

Thereafter, the electronic device 50 and the connecting assembly 10 are integrally mounted to the mounting assembly 20.

When the mounting assembly 20 and the connecting assembly 10 are mounted and fixed, the first fitting piece 12 and the second fitting piece 24 are mutually connected and matched to fix the connecting assembly 10 on the mounting assembly 20. Because the positions of the first mating member 12 and the second mating member 24 after being installed are corresponding, when the connecting assembly 10 is inserted into the accommodating space 23 of the ring-shaped member 22, the positions of the first mating member 12 and the second mating member 24 need to be staggered, so that the connecting member 11 is inserted into the accommodating space 23 at a first angle relative to the ring-shaped member 22, and then rotated at a second angle, so that the first mating member 12 and the second mating member 24 are connected in a matched manner. The specific values of the first angle and the second angle are not limited and can be set as required.

The direction in which the coupling assembly 10 protrudes into the receiving space 23 of the ring member 22 is a first direction, which is parallel to the rotation axis a when the coupling assembly 10 rotates in the receiving space 23.

The tool-free mounting device of the embodiment, by setting the connecting assembly 10 and the mounting assembly 20, the mounting of the electronic device 50 only needs to be fixed by the mounting between the connecting assembly 10 and the mounting assembly 20, and the mounting of the connecting assembly 10 and the mounting assembly 20 is realized by the relative rotation of the connecting assembly 10 and the mounting assembly 20, so that the first fitting piece 12 and the second fitting piece 24 are matched and connected, no tool is needed, the problem that the mounting tool is inconvenient to carry or suitable tools are temporarily difficult to find is solved, and the field mounting efficiency can be improved.
