Definitions
- the present invention relates to an attaching / detaching method for attaching or removing a contact top to a tip of a contact arm of a nailing machine such as a nail.
- a nailing machine drives nails such as nails and screws into a material to be driven and includes a contact arm as a safety device.
- One end of the contact arm protrudes from the tip of the injection tool's injection port, and the other end of the contact arm is linked to the trigger for starting.When the trigger is pulled, the one end of the contact arm is placed on the workpiece.
- the nailer is configured to operate only when hit.
- the panel is normally biased so as to protrude in the driving direction from the tip of the nose portion, and when the nail is driven, the tip of the contact arm is covered until the tip of the nose hits the driven portion. When it is pressed against the driving material, it moves in the direction opposite to the pressing direction, and this movement detects that the tip of the nose has been applied to the driven material, and trigger operation is enabled. It is structured as follows.
- the contact arm is pushed by pressing the contact arm against the workpiece, and the activation operation of the trigger valve that activates the driving tool is made effective.
- the tip of the contact arm is panel-biased so as to protrude in the driving direction from the tip of the nose portion, and when the contact arm is pressed against the driven material, the contact arm is pushed.
- the material to be driven is a relatively soft decorative material, the surface may be scratched or indented.
- a synthetic resin-made contour outer top is attached to the tip of the contact arm and then pressed.
- the contact top may or may not be used, it should be easy to detach and attach without using a tool such as a spanner.
- a tool such as a spanner.
- Such contact tops (nose caps) that are easy to attach and detach are known.
- the contact top convex portion is engaged with the concave portion of the contact arm simply by fitting it at the tip of the contact arm (push lever).

Therefore, there is provided a method for attaching and detaching a contact top in a driving tool, which can be easily and reliably performed so as not to come off during the driving operation of a nail.
- a nail ejection port is provided between a wear plate provided below the tool body and a driver guide disposed on the wear plate.
- the contact arm is slidably disposed along the nail driving direction at the lower end of the wear plate, and is provided in the vicinity of the injection port so as to be movable in parallel with the nail driving direction.
- an engagement groove is formed on the side of the contact top, and the contact top has the engagement groove on the contact
- the tip of the contact arm is in contact with the contact top, and is movable so as to protrude from the inside of the driver guide.
- the contact arm can be engaged with or engaged with the engagement groove of the contact top exposed from the inside of the driver guide with the tip of the contact arm moved downward as much as possible. Can be removed.
- the movement amount force of the contact arm may be added with a movement amount from the driver guide until the contact top is completely exposed to the movement amount in normal use.
- the contact top can be moved so that the engaging groove on the side portion protrudes and retracts from the inside of the driver guide, while the tip end portion of the contact arm is used as the contact top.
- the contact top When the contact top is exposed from the inside of the driver guide with the tip of the contour outer arm moved downward as much as possible, the tip of the contact arm contacts the tip of the contact arm. Engage with or disengage the top engaging groove. Therefore, according to the above attachment / detachment method, since it is not necessary to remove the driver guide when attaching / detaching the contact top, no tool is required, and therefore the contact top can be attached / detached very easily.
