The purpose of this utility model provide a kind of simple and reasonable, technological process reduce, easy to assembly, and can the energy-and time-economizing, the piezoelectric ceramics assembly of the electronic lighter that reduces production costs.

The utility model is made up of overcoat, interior cover, back-moving spring, impact spring, hammer, tup, piezo-electric crystal, square anvil, wherein back-moving spring, impact spring, hammer are arranged on the overcoat inner chamber, tup, piezo-electric crystal, square anvil are installed successively and are nested with in interior cover upper cavity, interior cover bottom is inserted in the overcoat inner chamber and is held out against hammer, cover bottom in the back-moving spring upper end holds out against, the impact spring upper end holds out against the tup bottom, be provided with the rotary steering structure between overcoat, the hammer, and interior cover hypomere is provided with symmetrical groove.

The utility model is owing to adopt the measure of optimizing the part arrangement position of adjusting, make full use of essential structure part conduction voltage and form two electrodes, a plurality of parts such as electric wire, copper pin have been reduced, processing steps such as injecting glue and drying have been saved simultaneously, make its structure simpler, easy to assembly quick, save the man power and material, reduce its production cost and price greatly.
