The invention relates to a tool for prying a heavy object. The tool for prying the heavy object is composed of a pry bar and a fulcrum fixing piece, the pry bar is provided with three parts, namely a pry bar head, a fulcrum area and a variable torque lever; a pinch bar head is flat; according to needs, a force applying rod can be connected to the tail end of a torque-variable lever, 1-3 fixed short shafts which are perpendicular to the pry bar and parallel to the ground are arranged in the fulcrum area. According to the tool for prying the heavy object, the fulcrum fixing piece is formed by fixedly connecting a plane heavy-duty bearing, an inner cylinder, an outer cylinder and the base up and down; the upper end face of the plane heavy-duty bearing is a cross-shaped notch formed by two notches which are perpendicular to each other; a bearing is arranged at the lower end of the cross-shaped notch; an inner-outer cylinder consists of an inner cylinder, an outer cylinder and a plurality of bolts; the base is fixed to the lower portion of the outer cylinder. According to the tool for prying the heavy object, an object prying tool can be adjusted by adopting various flexible methods according to different conditions such as the weight, the size and the position of a prying heavy object to meet the requirements of different conditions, and has the advantages of being simple in structure, convenient to use, mount, dismount and carry and suitable for various working environments.
