PURPOSE: A device for checking the motion of an exploding bolt is provided to check the separation state of a projectile holding device by forming a connecting unit behind the head portion of an exploding bolt and to control the exploding condition by adjustably setting up a current limit. CONSTITUTION: A device for checking the motion of an exploding bolt comprises an exploding bolt(200) having a connecting unit(210) for connecting another device, a thread unit(220) embedding a charging gunpowder, and a head unit(230) for connecting the thread unit with the connecting unit, a resistance unit(250) for stimulating the charging gunpowder of the thread unit, and a PCB(Printed Circuit Board)(240) having a circuit switched by the shock applied from the head unit of the exploding bolt when currents over a limit value flows through the resistance unit. According to the current over a limit value, the charging gunpowder in the thread unit is ignited. The head unit is separated from the thread unit. Then, the pressure of the head unit cuts off a circuit of the PCB. By checking the electrical signal of the circuit, the separation of the exploding bolt is detected.
