And can be applied directly to the tongue of the part with low adhesive strength, such as a concave part or sand on the surface to be processed, and can perform strong fishing. Even sand that has fallen can be dropped. Since a granular material having a shape such as a substantially spherical shape or a substantially spheroidal shape is filled in a hollow space so as to be free to flow with a certain space therebetween, a tongue portion in contact with a convex portion or the like of a workpiece is The granular material is pushed away and immersed in the hollow part. Since the volume of the hollow portion is constant, the displaced granular material flows in the hollow portion, and pushes out the orifice portion that is not in contact with the workpiece or is weakly in contact with the workpiece from the hole portion. Therefore, the impact force of the chisel can be made to follow the shape of the surface to be processed, and even when the surface to be processed has irregularities or the like, a high-quality drop can be performed. Since the fall prevention portion is formed at the base of the chisel portion, the chisel portion can be prevented from falling off from the main body. By installing locking members such as rolling bearings and sliding bearings in the adjacent buckles and concave portions formed on the inner wall of the main body, the buckles can be prevented from falling off and the Since they can be arranged, it is possible to perform a high-density hanging operation, a kernel operation, and the like, and it is possible to prevent the deformation by improving the bending strength of the head portion.
