Even if the protrusion 6D is formed by increasing the plate thickness only in the central portion,
As shown in FIG. 5, it may be formed by performing a burring process around the elongated hole 6C.

The hammer tacker having the magazine constructed as described above is filled with staples by straddling the rails 3 in the magazine 2 and is pressed by the feeder 5 toward the tip of the magazine 2. Abutting part 3 of 2
Staples are held between 1 and 1. The rails 3 are arranged inside the pair of staple legs, and the outer sides of the pair of staple legs are housed in the side edges 30A and 30B of the magazine 2. The magazine cover 4 is engaged with the elongated hole 6C of the driver 6, and the claw 35 of the magazine 2 is attached to the hook 28 of the head portion 13.
, The magazine cover 4 closes the opening of the magazine 2 so that they are integrated, and is projected from the head portion 13 at the position where the hook 28 and the claw 35 are engaged by the first return spring 20. It becomes a state.

In this state, when the ejection port 32 is hit by the handle 11 toward the object to be fixed, first the tip of the magazine 2 comes into contact with the object to be fixed, and then the head portion 13 moves toward the object to be fixed with the mass of the hammer head 12. Be hammered in. By the movement of the head portion 13 to the magazine 2 side, the driver 6 provided in the head portion 13 is guided into the magazine 2 by being guided by the guide surface 34 of the magazine 2, and the leading end of the driver 6 moves the staple connecting portion having the leading end. Strike toward the launch port 32. The protrusion 6D of the driver 6 engages with the guide groove 31A between the contact portions 31 of the magazine 2, and the thin-walled portion of the driver 6 enters between the contact portion 31 and the tip 38B of the rail 3 and is subsequently separated. Needle ejection port 32
Send out from.

The thickness of the thin portion of the driver 6 is as shown in FIG.
As shown in FIG. 7, the distance between the rail 3 and the contact portion 31 is set in accordance with the smallest thickness staple A to be applied, and when the smallest thickness staple A is applied, Even when the driver 6 enters the magazine 2, as shown in FIG. 8B, the rail 3 does not move backward, but guides the connecting portion of the needle with the contact portion 31.

When the thick staple A is ejected, the thickness of the staple A becomes larger than the distance between the contact portion 31 and the rail 3 end surface 38B, as shown in FIG. 9 (A). In this case, when the driver 6 enters the magazine 2, first, the connecting portion of the staple A is struck toward the ejection opening 32. This striking portion is closer to one side of the connecting portion of the staple A (closer to the contact portion 31), but can be separated. The separated connecting portion of the staple A pushes back the rail 3 to the rear side, and the contact portion 31 and the tip end 38 of the rail 3 are pushed.
As shown in FIG. 9 (B), it is advanced toward the launching port 32 while enlarging the interval with B so as to pass therethrough.

As described above, the rail 3 can be applied to a staple A having a thickness other than the target thickness of the staple A by retracting the rail 3 in accordance with the thickness of the staple A.

Further, as shown in FIG. 10A, from the staple A having the outer shape of the size of guiding on the inner surfaces of the side edges 30A and 30B of the magazine 2, the size of the outer surface of the side edge of the rail 3 on the outer side Even a staple A having a shape can be applied. For the intermediate staple A which cannot be guided by the side edges 30A and 30B of the magazine 2 and the side edge of the rail 3, FIG.
As shown in 0 (B), the staple A is sandwiched between the contact portion 31 of the magazine 2 and the feeder 5, so that the staple A can be held without inclining in the plane.
This is possible because the staples A are regularly stacked.

When the hammer tacker hits, the magazine 2 first comes into contact with the object to be fixed, and then the hammer portion 13 of the hammer body 1 is moved toward the object to be fixed. During this movement, the reaction force of the coil-shaped first return spring 20 acts, and then the second return spring 23 contacts the magazine cover 4. The impact load acting on the fixed object is the first return spring 20.
In addition to the action of the second return spring 23, the second return spring 23 acts in a stepwise manner to prevent damage to the object to be fixed due to a sudden increase in the impact load, while removing the change in the reaction force applied to the hand holding the handle 11. The work load can be reduced in the first place.

When the number of staples decreases as the work progresses, the position of the feeder 5 pressing the staples against the contact portion 31 of the magazine 2 approaches the contact portion 31. Since the detection mark 45 is provided on the side surface of the feeder 5,
The detection mark 45 is exposed in the detection hole 36 provided on the side surface of the magazine 2 to notify that the number of staples is small.

In this embodiment, the effects described below can be obtained. That is, the rail 3 is provided so as to be movable in the longitudinal direction, the front end of the rail 3 can partially close the ejection port 32 of the staple, and the width of the ejection port 32 can be changed. Since the rail spring 40 is urged, the rail 3 is retracted by the staples separated at the time of driving the relatively thick staples, the relatively thick staples can be driven, and the staples having different thicknesses can be driven.

A pressing portion which is formed so that the distance between the rail 3 into which the staples to be accommodated are inserted and the side edges 30A and 30B of the magazine 2 is larger than the thickness of the staples to be accommodated and which abuts at least the staples of the feeder 5. Since 44 is formed wide so that the foot of the inserted staple can be pressed, staples having different shoulder widths can be accommodated and ejected.

Since the magazine 2 is provided with the detection hole 36 and the feeder 5 is provided with the detection mark 45, the detection hole 36 is provided.
Through, it is possible to display the accommodation state of the staples.

A driver 6 is mounted on the hammer portion 13 of the hammer body 1.
Since the magazine 2 is swingably provided on the hammer main body 1, the present invention can also be applied to a hammer tacker that hits a staple on a fixing target by striking.

Since the object to be fixed is hit through the first and second return springs 20 and 23, the hitting reaction force is prevented from rising rapidly, and damage to the object to be fixed can be prevented.
The reaction force applied to the hand holding the handle 11 also changes in a reciprocal manner, and the work load can be reduced.

In the above embodiment, the hammer portion 1
Although the hammer tucker that ejects the staples accommodated in the magazine 2 from the ejection port 32 by the driver 6 of No. 3 has been described, the tucker equipped with a driver driven by a fluid force such as electric power or air is also included in the driver, although not shown. The present invention can be applied only to the driving method different from.

Further, although the staples which are driven into an object when being ejected have been described, the present invention can also be applied to a stapler whose tip is bent through the object although not shown. Further, the staple is not limited to those formed of metal, but plastic,
It is also applicable to staples formed of resin.
