Description

  The present invention relates to a punching tool such as a pin, and more particularly to a manual punching tool for a nail for fixing wood or a fastening pin for fixing a paper material (hereinafter referred to as “pins”).

  When using a conventional extraction tool such as a pin, it is necessary to collect and hold the pin extracted with another hand while holding the extraction tool with one hand. In general, when a certain number of pins are collected, they are transferred to a portable work bag or moved to a nearby work table.

  However, when holding a pin or the like with a hand, a pointed needle part may injure the hand. In particular, when the number of holdings increases, the danger increases because needle portions such as pins are directed in various directions.

  Also, carelessly dropping pins etc. from the hand and scattering them on the floor is dangerous, so it is necessary to interrupt the removal operation and collect the pins etc. each time. It is troublesome to get down on the floor one by one, especially when you are pulling out at high places such as ladders or stepladders.

  Furthermore, when pulling out at a high place such as on a ladder or stepladder, as described above, one hand is pulled out, and the other hand is blocked by a pin or other means, so there is no means to hold the body. There is also a risk of becoming unstable and falling.

  In view of the current state of the prior art, the object of the present invention is to remove pins etc. with one hand, and to automatically and safely collect and hold a number of removed pins, etc. It is to provide a punching tool such as a pin.

  For this reason, the punching tool of the present invention comprises a head and a handle made of a rigid material that are coupled to each other in a refracted monolithic structure, and a V-shaped punching groove having an inner blade is formed at the tip of the head. The gist is that the handle has a case shape that opens only toward the head.

  The pins after they are automatically dropped and collected in the head one after another are collected and held, so you can pull them out with just one hand, especially when you are at high places, and you can avoid hurting your hands. .

  FIG. 1 shows an embodiment of the punching tool of the present invention. This punching tool is composed of a head 1 and a handle 7 which are mutually coupled in a refracted integral structure. The head 1 and the handle 7 are made of a rigid material such as metal or hard plastic.

  A V-shaped punching groove 3 having an inner blade 5 that engages with a pin or the like during a punching operation is formed at the tip of the head 1.

  The handle 7 has a case shape having an opening 9 only toward the head 1. Also, it is convenient to close the opposite end with a removable cap or the like because the cap can be removed and discharged when the collected pin is full.

  When the punching tool is used only for pinning work, it is desirable to reduce the weight by forming the entire punching tool from a hard plastic material. In addition, if the head and the handle have the same width and are relatively wide, the work is easy. Handle 7 need not be too long. Further, it is desirable that the refraction angle between the head 1 and the handle 7 is relatively large so that the whole is compact.

  When the punching tool is used only for nail pulling work, it is desirable that the entire punching tool is made of metal to give strength. However, even in this case, the portion other than the upper wall of the handle 7 can be made of hard plastic to reduce the weight. The handle can be lighter even if it is narrower than the head. If the handle 7 is relatively long, the lever principle can be used effectively in the punching operation. It is advantageous from the viewpoint of work to make the refraction angle between the head 1 and the handle 7 smaller than in the above case.

  In use, with the inner blade 5 of the punching groove 3 of the head 1 engaged with the head of a pin or the like, the heel portion of the punching tool (below the refractive coupling portion of the head and the handle) is pressed against the wall or wood. Then, when the handle 7 is pushed down with the hand at the center, the pin etc. is pulled out. In this state, when a pin portion such as a pin is lightly applied to a wall or wood, the pin or the like is disengaged from the inner blade 5 and falls into the handle 7 by gravity, and is automatically collected and held. . This operation can be easily performed with only one hand. When the pulling operation is repeated and the inside of the handle 7 is filled with pins or the like, it may be discharged appropriately.

  It can be widely used for pin removal work at construction sites, offices, and homes.

It is a perspective view of one Example of extraction tools, such as a pin of this invention.
