Abstract: An internal rotor type nail drive device of electric nail gun, comprising a nailing rod and an internal rotor type rotary actuator that can output a specific rotation angle and can drive the nailing rod to move downward for nailing. Specifically, the rotary actuator comprises a stator and a rotor arranged inside the stator, even groups of electromagnetic mutual action components are configured in pairs between the stator and the rotor, to generate a tangential force to drive the rotor to rotate for a specific rotation angle, and to drive the nailing rod to move for a nailing stroke. The nailing stroke can be determined by a specific rotation angle. Thus, through the above configuration of the rotary actuator, the structure of the electric nail gun can be simplified, and the kinetic energy for nailing can be increased.

Abstract: A multilayer capacitor includes a dielectric main body having opposite first and second sides, a terminal electrode assembly and spaced apart first, second and third inner electrodes, all of which are disposed in the main body. The second inner electrode is disposed between the first and third inner electrodes. The terminal electrode assembly has a first terminal electrode unit disposed on the first side and connected to the first inner electrode, a second terminal electrode unit disposed on the second side and connected to the second inner electrode, and a third terminal electrode unit disposed on the first side and connected to the third inner electrode. The first, second and third terminal electrode units are insulated from each other.
