Abstract
A nail tip guide tool is attached to an end of a nose of a nailing machine to provide guide pieces on a bottom surface inside same, the nail guide tool having a lower portion in a funnel shape. The top surfaces of the guide pieces have a recess in a mortar shape when brought together at the center of the funnel shape by a press board member biased by a coil spring. The guide pieces are used so that in the nose, the tip of a nail in an inclined posture is guided to a center of the mortar shape and is inserted thereamong, and correcting the posture thereof. For fastening a metal piece with a nail, distal ends of the guide pieces are structured to form a conical shape, and with this portion having been fitted into a pilot hole of the metal piece, the nail is struck.
Claims6
A nail tip guide tool of a nailing machine, which is used by being mounted to a tip portion of a nose portion forming a passage for driving out various nails from the air the nailing machine, the nail tip guide tool comprising:
- a guide piece molded such that when a plurality of guide pieces are gathered together at a central portion of an inclined bottom surface of a funnel-shaped container, a mortar-shaped recess portion is formed at a central portion of an upper surface of an aggregate of the plurality of guide pieces;
- a protrusion portion provided on an outer peripheral portion of an upper surface of the guide piece and fitted into a recessed rail radially provided on a lower surface of a torus-shaped press board;
- a coil spring having extension elasticity is fitted into both a circular groove for receiving the coil spring, which is provided on an upper surface of the torus-shaped press board, and a circular groove for receiving the coil spring, which is provided on a lower surface of a lid of the funnel-shaped container;
- the lid of the funnel-shaped container and the funnel-shaped container are joined together by screw threads provided at the lid and the funnel-shaped container;
- the nailing machine and the nail tip guide tool are joined together by a screw thread provided at the lid of the funnel-shaped container to correspond to a screw thread provided at an outer peripheral portion of the tip portion of the nose portion of the nailing machine;
- a tip of a nail driven in a tilted posture from the nose portion is guidable to a central portion of the mortar-shaped recess portion;
- and
- the nail is capable of being pushed in at a position of the central portion of the mortar-shaped recess portion so that the plurality of guide pieces are pushed and expanded to right and left and grip and surround a nail shaft portion of the nail to straighten a posture of the nail.
