BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a staple striking aid used for striking staples onto a wooden drum, a flat plate or the like with a hammer or the like safely and without fail.

[0002]

2. Description of the Related Art Staples (U-shaped staples) for stopping ends of cables and the like on wooden drums, flat plates and the like.
In the case of hitting with a hammer, conventionally, there is no dedicated auxiliary tool for holding the staple, and the staple is sandwiched and held by the surrounding pliers or radio pliers, or directly held by one hand and the hammer is held by the other hand. I was working on it.

[0003]

However, a pinching tool having a groove, such as pliers, is capable of gripping one nail of a staple, but not both nails, and the nail is line-contacted. Since it will be sandwiched by, the gripping force is weak,
There is a problem that it is unstable as an auxiliary tool.

Further, since both the pliers and the staple are made of metal which easily slips, there is a problem that the holding force is weak. When the staple holding state becomes unstable in this way, the staples may come off from the pliers and jump out depending on the impact when hammering in and the driving angle, which may damage people and objects. There is a risk that it will end up.

Further, in the actual striking work, since the pliers and the hammer are handled by the fingers of the left and right respectively, it is necessary to pay attention to both hands, the attention is distracted and the striking easily occurs. There is a problem that it causes the disaster of.

In the case of directly grasping and holding staples with fingers and striking the staples, since the holding force is considerably small and the two nails of the staples have different lengths, it is difficult to strike them vertically and the staples are damaged. There is a problem that it occurs, and if you staple it until you do not need to hold it with your fingers, the length from the wood surface to the head of the staple will be smaller than the distance between the fingers you are grasping, and the holding will gradually increase. There is a problem that it becomes difficult. In addition, there is a risk of hitting a finger with a hammer, and there is a risk that staples may fly due to insufficient holding force, resulting in an accident.

An object of the present invention is to provide a staple driving assisting tool capable of stably holding staples during staple driving.

[0008]

According to a first aspect of the invention, a tip portion of a grip bar is formed of an elastic body, and a split portion for elastically fitting and holding a staple driven into a plate or the like is held at the tip portion. It was formed.

In a second aspect based on the first aspect, the tip portion is formed to have a height of 1/2 to 2/3 of the height of the staple, and the split portion is the tip portion of the grip bar. A through hole formed by vertically penetrating each of the staples to elastically fit therein, and a slit formed by crossing the through hole along a plane passing through the axis of the through hole. It was done.

According to a third aspect of the present invention, in the first aspect, the split portion is formed of a slit formed in the lower surface of the grip bar so as to elastically fit the head of the staple through the opening. It is a thing.

[0011]

In the first aspect of the invention, when the staple is fitted in the split portion, the staple is held in the split portion without being tilted or twisted by the elastic force of the elastic body acting on the staple. After that, by holding the grip bar and applying the nail tip of the staple to the plate or the like and striking the staple, the staple is safely driven into the plate or the like without mistake. After that, the gripping bar is pulled in the direction opposite to the driving direction to remove the split portion from the staple, and then the head of the staple is hit to drive the staple to a desired depth.

According to the second aspect of the invention, when the staple nail is fitted into each through hole from above the upper surface of the split portion, the slit is widened, and the reaction force due to the widening is used as a holding force for the staple nail. Act on. After attaching the staples, hold the grip bar, apply the nail tips of the staples to a plate, etc., and strike the heads of the staples to drive the staples to the depth. When the driving depth reaches the height of the tip of the grip bar, pull the grip bar in the direction opposite to the driving direction to remove the split part from the staple, and then tap the head of the temporarily stapled staple to staple it. Hit the target depth. At this time, since the nail is provisionally hammered into the plate or the like, the holding force does not tilt or twist the staple. Where the height of the tip is 1 of the staple height
Since it is / 2 to 2/3, the provisional driving depth of the staple becomes 1/3 to 1/2 of the staple, which prevents the inclination and fall of the staple when the staple is additionally driven.

In the third invention, when the head of the staple is pushed into the slit, the head of the staple is held by the elastic force acting on the staple without tilting or twisting, and the tip of the staple is fixed. It is in a state of protruding from the tip of the grip bar to the lower surface. After mounting the staples, apply the nail tip of the staple to the driven surface, hit the upper surface of the tip until the lower surface of the tip hits the driven surface, and when the lower surface hits the driven surface, use the grip bar. Is pulled in the direction opposite to the driving direction to remove the slit from the staple, and then the staple is additionally driven to finish the attachment of the staple.
