1. A trigger device, comprising a trigger bracket and a trigger (1) movably arranged on the trigger bracket, further comprising:
a trigger electromagnet (3), which is fixed on the trigger (1);
a bracket electromagnet (2), which is fixed on the trigger bracket, and has an effect of attracting or repulsing with the trigger electromagnet (3) in a pressed state;
an electromagnetic control device, which is connected to the electromagnetic coil (4) of the trigger electromagnet (3) and the electromagnetic coil (4) of the bracket electromagnet (2) respectively, and is configured to adjust the voltage or current of the electromagnetic coil (4) of the trigger electromagnet (3) and the electromagnetic coil (4) of the bracket electromagnet (2),
wherein the number of turns of the electromagnetic coil (4) of the trigger electromagnet (3) is the same as the number of turns of the electromagnetic coil (4) of the bracket electromagnet (2), and the size of the trigger electromagnet (3) and the bracket electromagnet (2) are the same,
when the trigger (1) is fully pressed, the trigger electromagnet (3) and the bracket electromagnet (2) are arranged in parallel with a gap.
