Abstract: Disclosed herein is a smart electroshock device. The smart electroshock device includes: a main body provided therein with electronic components to launch a projectile, the projectile being adapted to be stuck in a target and apply an electric shock to the target; a cylinder body coupled to one side of the main body via a hinge and comprising a cylinder; and a plurality of cartridges mounted in the cylinder and each comprising the projectile, wherein the projectile is launched from the cylinder through manipulation of the main body, and the cylinder is rotatably coupled to the cylinder body. The smart electroshock device according to the present invention can launch a plurality of projectiles consecutively using a revolving cylinder. In addition, the smart electroshock device can be used as a stun gun without removing a projectile in the cartridge which is in a state to be launched.
