Stun gun with an extendable electric shock distance

A stun gun with an extendable electric shock distance comprising:

• a high voltage electric arc generator generating a high voltage electric arc and having:
• a housing having a front end and a rear end;
• a first electrode and a second electrode mounted in the front end of the housing;
• a voltage booster mounted inside the housing and electrically coupled to the first electrode and the second electrode;
• a battery set mounted inside the housing electrically coupled to the voltage booster;
• a trigger switch mounted on the housing and electrically coupled between the voltage booster and the first electrode;
• a spray tube configured inside the housing and having a first end and a second end, wherein the first end is located between the first electrode and the second electrode;
• a pressure container mounted inside the housing, filled with conductive liquid and comprising a spray nozzle connected and against to the second end of the spray tube;
• and
• a switch part configured on the housing and passing through the housing to be connected to the spray tube, wherein the switch part is pushed to slide on the housing to drive the spray tube to move inside the housing, wherein a sliding path of the switch part on the housing goes to be connected to the trigger switch;
• and
• a conductive liquid supplier filled with a conductive liquid, wherein the conductive liquid is spurted from the conductive liquid supplier and then the liquid is passing through the high voltage electric arc of the high voltage electric arc generator.
