Contact type arc striking plasma high-voltage igniter

The invention provides a contact type arc striking plasma high-voltage igniter, which relates to the field of plasma igniters, and comprises an anode, an insulating part, a cathode, a cathode head, an insulating inner sleeve, an elastic element and a limiting transmission assembly, a first limiting bulge is arranged on the surface, close to the head part, of the cathode head, a second limiting bulge is arranged at the tail part, and two ends of the elastic element are respectively propped between the axial inner wall of the insulating inner sleeve and the first limiting bulge; the limiting transmission assembly is arranged in an annular space formed between the cathode head and the cathode channel in a surrounding mode and used for adjusting and controlling the axial moving position of the cathode head. The device can simultaneously meet the application of working environments such as contact type arc striking and high-voltage resistance, and has the advantages of simple structure, easiness in implementation,
