The present invention relates to a nail pulling device. The nail pulling device includes: a housing; a cylinder installed within the housing, the cylinder including a piston operated by an air or oil pressure and a piston rod connected to the piston; a stopper passing through the piston rod of the cylinder and fixed to an outer surface of the piston rod so as to ascend or descend along the piston rod; a jaw holder disposed under the stopper, the jaw holder having a top surface through which the piston rod of the cylinder passes and an inner diameter gradually increasing downward; a jaw guide fixed to an outer surface of a lower end of the piston rod of the cylinder so that the jaw guide is spaced a predetermined distance from the stopper so as to ascend or descend along the piston rod, the jaw guide ascending or descending within the jaw holder; and a jaw rotatably installed on the jaw guide so as to pull a nail from a specific object when the piston rod of the cylinder ascends after the jaw grasps the nail stuck in the specific object. Thus, the nail may be easily pulled without using a labor force. |
