  As conventional techniques, a cylindrical main body in which a plurality of pushpins having rod-shaped heads connected in the width direction are slidably inserted, a punching guide for punching out individual pushpins provided at the tip of the cylindrical main body, and a punching guide The piston for launching the thumbtack on the head side of the head, the launching lever attached to the rear part of the piston and equipped with automatic return means, the thumbtack replenishing port provided at the rear end of the cylindrical body, and the thumbtack replenishing port are opened and closed There is a thumbtack launcher characterized by having a lid. (See Patent Document 1)

  JP-A-9-207498 (Claim 3, FIG. 4)

However, the thing of the above forms must use a dedicated thumbtack (rod-shaped head), and when the thumbtack is cut, it can only be purchased at a specialty store, and the work may stop.
In addition, since it is a dedicated thumbtack, the cost is high, and since the head is rod-shaped, it cannot be used for posters, banners, etc. that are heavy. (There is a risk of tearing)
The present invention has been made in view of the above-described problems, and a thumbtack can be driven with a hammer by a simple operation of pulling a lever, and a thumbtack of a circular head can be reliably secured by a moving tool / alignment tool. The purpose of the present invention is to provide a thumbtacking machine that can be driven into.

  As means for solving the problem, an arm provided with a locking piece at the tip that descends by pulling a lever provided on the thumbtack main body, and a locking portion for locking to the locking piece of this arm are provided. A hammer, an extruding pin provided below the head of the hammer, a push pin driven by the extruding pin one by one forward, a moving tool positioned at the lower end of the extruding pin, and an alignment for aligning the push pin Provide tools. Also, a pulling tension spring is provided on the lever, a pressing tension spring is provided on the hammer, a supporting compression spring is provided on the push pin, and the moving tool is a winding spring. Provide a magnet at the bottom of the push pin. Furthermore, the locking piece of the arm pushes up the hammer, disengages from the locking portion of the hammer at a fixed position, and hits the hitting portion of the push pin with the pressing tension spring. The alignment tool must be formed in a rail shape and support the thumbtack head. In addition, the thumbtack is characterized by using a circular head.

1) The thumbtack can be driven with a hammer by a simple operation of pulling the lever.
2) Due to the action of each spring, the thumbtack can be driven in with certainty while having a simple structure.
3) By using the moving tool as a winding spring, the thumbtack can be sequentially pushed forward.
4) The alignment tool can be surely aligned one by one by forming it in a rail shape and supporting the thumbtack head.
5) In particular, when stopping heavy objects such as curtains, anyone can easily and easily work without requiring labor.
6) Since a thumbtack having a round head such as a conventional product can be used, even if the thumbtack disappears during work, it can be purchased at a nearby stationery store or the like, which is very convenient.

1 is a thumbtacking machine.
Reference numeral 2 denotes a thumbtack main body formed with a handle 2a made of synthetic resin or the like.
Reference numeral 3 denotes a lever supported by a pin 3a, which is provided with a pulling tension spring 3b at the tip and is always supported upward.
Reference numeral 4 denotes an arm supported by a pin 4a at the front portion of the lever 3, which is provided with a locking piece 4b at the tip and a compression coil spring 4c, and always presses the arm 4 forward.
Reference numeral 5 denotes a hammer provided with a locking portion 5a for locking to the locking piece 4b of the arm 4 at the rear and a head 5b provided in front, supported by a pin 5c, and pressed by a pressing tension spring 5d. It is always pressed downward.
An extruding pin 6 is provided below the head 5b of the hammer 5 and has a replaceable special steel hitting portion 6a at the top, a magnet 6b at the bottom, and a supporting compression spring 6c at the center. It is provided.
7 is a moving tool which pushes forward a thumbtack having a circular head driven by the push-out pin 6 one by one and positions it at the lower end of the push-out pin. An extrusion plate 7b to be inserted into the groove is provided.
8 is an alignment tool for aligning the thumbtack G, is formed in a rail shape, is provided with a groove 8a, and is provided with the push-out plate 7b in and out.

Next, an example of using the thumbtack machine 1 will be described below.
For example, when attaching the banner T in a funeral or the like, the pulling coil spring 3b is pulled down by pressing the banner T against the wooden frame K, positioning the push pin 6 of the thumbtacking machine 1 at the required location, and holding the lever 3 upward. When the arm 4 is lowered and the arm 4 is lowered, the locking portion 5a of the hammer 5 is lowered by the locking piece 4b, and the head 5b of the hammer 5 is raised.
At this time, the pressing tension spring 5d is extended. At the same time, the push pin 6 is lifted by the supporting compression spring 6c, and the push plate 7b is pushed forward by the winding spring 7a of the moving tool 7. It is located at the lower end of the push pin 6 and is attached by a magnet 6b.
Subsequently, when the lever 3 is further gripped, the locking piece 4b of the arm 4 is disengaged from the locking portion 5a of the hammer 5, and at the same time, the pressing tension spring 5d is contracted (reaction force), and the head 5b of the hammer 5 is pushed out. The hitting portion 6a of the pin 6 is hit, the supporting compression spring 6c is contracted, and the thumbtack G is driven into the wooden frame K by the magnet 6b, so that the banner T can be fixed.

Thus, the thumbtack G can be driven continuously by grasping the lever 3.
Each spring has a well-balanced force and is not particularly limited in size.
In addition, various applications are conceivable and may be used as necessary.

  The thumbtack machine can use a thumbtack with a circular head due to the above structure, and can push a thumbtack with a hammer by a simple operation of pulling a lever. It is an improvement in work efficiency and has very high industrial applicability.
