Push-type friction nanometer generator capable of improving low-frequency output

The invention designs a push-type friction nanometer generator capable of improving low-frequency output. Under low-frequency small-load push excitation of the device, through a structural design, the amplitude and frequency of an output voltage and current of the friction nanometer generator device are remarkably improved, meanwhile, key parts of the device are effectively protected structurally, the service life of the device is prolonged, and the thickness of the insulating spacer is properly designed so that the deformation of the spring steel sheet and the positive electricity conducting plate can be limited in a reasonable range, the damage of the conducting plate caused by overlarge deformation is avoided, and the service life of the device is prolonged; and generation of electric signals is based on the principle of triboelectrification and electrostatic induction, positive electricity materials and negative electricity materials are wide in selection, the overall structure is simple and labor-saving,
