[0011] By adopting the above-mentioned technical solution, the trigger mechanism provided by the utility model has the following beneficial effects:

[0012] In the use of related electronic products, when in a non-triggering state, the trigger column rests against the non-positioning hole area on the cover plate, and the elastic element is in a compressed state at this time; when a certain function needs to be triggered, the rotary knob is turned, and when the trigger column reaches the positioning hole position, the elastic element opens, and the elastic force generated pushes the rotary knob to move until the trigger column is pushed into the positioning hole and continues to apply pressure to the button assembly, thereby completing the continuous triggering work. In summary, by adopting this trigger mechanism, different function buttons can be triggered at the same position through the rotation of the rotary knob, and the triggering is continuous. Compared with the traditional structure, the structure is simplified, the cost is reduced, and it is easy to operate, which effectively improves the user experience.

[0015] As an improvement, the bracket and the inner frame are both configured as an annular structure.

[0016] As an improvement, the electrode is provided in plurality; and the bracket is provided with an FPC component accommodating groove.

[0017] By adopting the above-mentioned technical solution, the beneficial effects of a wearable device provided by the utility model are as follows:

[0018] When the wearable device is in use, it obtains human body signals through electrodes. When it is in a non-triggering state, the trigger column rests against the non-positioning hole area on the cover plate, and the elastic element is in a compressed state at this time. When a certain function needs to be triggered, the rotary knob is turned.

In summary, by using this wearable device, different function buttons can be triggered at the same position by rotating the rotary knob, and the triggering is continuous. Compared with the traditional structure, the structure is simplified, the cost is reduced, and it is easy to operate, which effectively improves the user experience.
