  However, in such a tip locking tool, the tip is gripped by sandwiching the proximal end portion of the tip between a plurality of claw pieces each extending obliquely forward from the tip of the support. Therefore, it is practically difficult to grip the chip in the direction along the axial direction of the pull-in bar.

  In addition, if the tip cannot be gripped in the direction along the axial direction of the pull-in rod, and the tip is pulled into the cylindrical member by pulling the pull-in rod, the pull-in rod is Even if it is pulled correctly in the direction along the direction, there arises a disadvantage that the tip is locked in a direction not along the axial direction of the cylindrical member with respect to the cylindrical tip of the cylindrical member.

  Furthermore, even if the tip can be gripped in the direction along the axial direction of the retracting rod, such a tip is gripped in an unstable state between a plurality of claw pieces each extending obliquely forward. Therefore, it is considered that it is considerably difficult to lock the chip in the direction along the axial direction of the cylindrical member.

  Accordingly, an object of the present invention is to reliably avoid the inconvenience that the tip is locked in a direction not along the axial direction of the cylindrical member with respect to the cylindrical tip of the cylindrical member, and the tip is assembled to the cylindrical member. An object of the present invention is to provide a tip locking tool capable of reducing the work burden at the time.

It is preferable to provide a support portion that protrudes toward the inside of the piece and supports the bottom portion of the chip held by the claw piece.

  From the standpoint of further reducing the work load when assembling the tip to the tube tip of the cylindrical member so that the tip can be quickly and easily set in a set of direction restraint sections, Each piece is made up of each front end side portion that is bent by outwardly bending each front end side portion, which is the front end side portion of each front end side portion, and the base end side portion of the chip is constrained as a set of directions. It is preferable to have a set of guide sections that guide to the sections.

  Further, the basic function of the present invention is to lock the tip to the tube tip of the cylindrical member so as to increase the gripping force that the claw piece exerts on the tip drawn into the tube tip as much as possible. From the viewpoint of securing the tip, the tip is pulled out of the nail piece drawn into the tip of the tip by being recessed into the outer periphery of the tip drawn into the tip of the tip. It is preferable that a protrusion for preventing the above is provided.

  Furthermore, from the viewpoint of more reliably and stably grasping the tip and further reducing the work burden when assembling the tip to the cylindrical tip of the cylindrical member, the inner peripheral surface of the claw piece can be reduced. Is preferably provided with a hook that prevents the tip from being pulled out of the claw piece by being caught on the outer peripheral surface of the gripped tip.
