1. A nail gun for striking nails, comprising:
an energy storage mechanism comprising a piston and at least one power spring having a first end abutting against the piston and being configured to be compressed to store energy;
a pushing component comprising at least one pushing section facing the piston for driving the piston towards the at least one power spring for compressing at least one power spring;
a drive motor for driving the pushing component to rotate; and
a control mechanism for controlling the energy storage mechanism,
wherein the control mechanism comprises a main switch configured to produce a first electronic signal and a safety switch configured to produce a second electronic signal;
wherein the main switch and the safety switch are in communication with the drive motor that is configured to operate when both the first electronic signal and the second electronic signal are received;
wherein the main switch comprises a pressing part and a main switch component; and wherein the safety switch comprises a toggling part and a safety switch component; and
wherein the toggling part comprises:
a toggle blade which is configured to contact an activation point of the safety switch component to generate the second electronic signal;
a toggle rod having a first toggle rod end configured to contact the pushing component and a second toggle rod end configured to contact with the toggle blade to push it to disconnect from the activation point of the safety switch component; and
a toggle blade seat having a toggle blade reset spring; wherein a first end of the toggle blade reset spring is in contact with the toggle blade; and a second end of the toggle blade reset spring extends out of the toggle blade seat and is in contact with the toggle rod; and
wherein the toggle blade is hook-shaped and comprises a contact plate for contacting the activation point of the safety switch component, a toggling plate for contacting the toggle rod, and a connecting plate connecting the contact plate and the toggling plate.
