[Detailed description of the invention]

[0001]

2. Description of the Related Art There is generally known a driving tool for stapling relatively thin metal plates or between a metal thin plate and a wooden plate. Since this tool requires a large driving force and uses compressed air or electric power as a power source, it cannot be used in a place where there is no air system or power wiring equipment. Further, since a large piston / cylinder mechanism or a relatively large electric motor is used as a driving source, there is a problem that the weight of the entire tool is increased and workability is impaired.

[0002]

The object of the present invention is to provide a staple driving tool which can solve the above-mentioned drawbacks and can be stapled to a thin metal plate or the like only by human power without requiring a power source such as compressed air or electric power. Aim.

[0003]

In order to achieve the above object, a staple driving tool according to the present invention comprises a C-shaped jaw having a clincher at one end and a clincher at the other end facing the clincher. A staple magazine having a staple launching path and a staple magazine for supplying staples to the staple launching path, and a slider in which a driver integrally fixed with a driver sliding along the staple launching path are slidably disposed. A connecting rod and a resilient spring are interposed between the staple magazine and the slider so that the slider and the staple magazine are maintained at a fixed interval determined by the connecting rod by the resilient spring. And a fixed handle on the slide guide opposite to the staple driving direction. A movable handle having one end pivotally supported on a part of the jaw, and a toggle link provided between a middle portion of the movable handle and the slider to form a toggle link mechanism. I do.

[0004]

The operation of the staple driving tool having the above configuration will be described. First, the leading staple in the staple magazine is supplied to the staple driving path. Then, when the adherend is disposed between the jaw clincher and the staple magazine, and the movable handle is turned to the fixed handle side, the toggle link mechanism operates and the slider slides. When the slider slides, the staple magazine also slides along the guide groove via the resilient spring, and the tip of the staple magazine hits the adhered object, and the adhered object is sandwiched between the staple magazine and the clincher. When the slider is further slid, the driver launches staples while holding the adherend at a constant pressure while pressing the resilient spring, and the staple legs are bent by the clincher after penetrating through the adherend to complete the operation. .

1 and 2 are a side view and a bottom view of a staple driving tool. This driving tool has a C-shaped jaw 1 formed with a clincher 2 at one end and a slide guide 4 at the other end. The slide guide 4 includes a slider 6 having a driver 5 (see FIG. 3) and a staple. A magazine 7 is slidably disposed, and a toggle link mechanism a is formed between a fixed handle 8 extending from the slide guide 4 and a movable handle 9 pivotally attached to the jaw 1, and the movable handle 9 is pushed. By doing so, the driver 5 is driven together with the slider 6 to drive the staples supplied to the staple driving path in the staple magazine 7 toward the clincher 2 to stap the adherend 25.

The clincher 2 is formed on a clincher holder 10 formed at one end of the jaw 1, and a clincher groove 11 is formed at the tip.

The slide guide 4 has a continuous guide groove 1
The staple magazine 7 and the slider 6 are slidably disposed in the guide groove 12.

As shown in FIGS. 3 to 5, the staple magazine 7 has a staple driving path 3 formed therein. The open end of the staple driving path 3 is formed so as to face the clincher 2. A staple magazine 7 and a slide path 14 for a staple leg regulating member 13 are formed in the staple launch path 3.
The staple magazine 7 protrudes from the side of the slide guide 4. A staple supply path 15 is formed inside the staple magazine 7, and a pusher 17 that biases a spring so as to supply the stored staples 16 to the ejection path 3. Are located. Further, the slide path 14 of the staple leg regulating member 13 is disposed in parallel with the ejection end side of the staple supply path 15, and as shown in FIGS. 4 and 5, the staple legs on both sides of the staple supply path 15. It is formed narrower by the amount. An inclined surface 13a is formed at a portion of the staple leg regulating member 13 facing the launch path 3, and a compression spring 18 is disposed on the back surface thereof. For this reason, the staple leg regulating member 13 is always urged by the compression spring 18 to the inclined surface 13.
a retreats from the staple launching path 3, the leading end enters the staple launching path 3, and a part of both side surfaces 13b of the staple leg regulating member 13 is inside the staple leg 16a in the staple launching path 3. It is urged to close.

A driver 5 is integrally fixed to the slider 6, and the driver 5 is slidably accommodated in a driver guide passage 19 which is continuous with the staple driving path 3.

A resilient spring 20 is provided between the staple magazine 7 and the protruding piece 6a projecting sideways from the tip of the slider 6.
The connecting rod 21 is fitted. One end of the connecting rod 21 is fixed to the staple magazine 7, and the other end thereof slidably penetrates the protruding piece 6a.
Are formed. As a result, the slider 6 and the staple magazine 7 are urged by the resilient spring 20 so as to maintain a fixed interval determined by the connecting rod 21.

Next, as shown in FIGS. 1 and 2, a fixed handle 8 is extended from the slide guide 4 in a direction opposite to a direction in which the staples 16 are driven. 22 is a grip. On the other hand, a part of the jaw 1 is provided with a movable handle 9 having one end pivotally supported. The movable handle 9 includes a handle body 9a and a handle link 9b. 23 is a grip. Further, a toggle link 24 is provided between the middle part of the movable handle 9 and the slider 6, and these constitute a toggle link mechanism a.

The mode of use of the driving tool for the staple 16 having the above configuration will be described. First, the leading staple 16 in the staple magazine 7 is supplied to the staple driving path 3 as shown in FIG. Then, the adherend 2 is located between the clincher 2 of the jaw 1 and the staple magazine 7.
5, the movable handle 9 and the fixed handle 8 are grasped by hand, and the movable handle 9 is turned to the fixed handle 8 side, the toggle link mechanism a is activated and the slider 6 moves along the guide groove 12. Slide. When the slider 6 slides, the staple magazine 7 also slides along the guide groove 12 via the resilient spring 20, and the tip of the staple magazine 7 hits the adherend 25 as shown by a dotted line in FIG. Is sandwiched between the staple magazine 7 and the clincher 2. When the slider 6 is further slid, the driver 5 slides in the driver guide passage 19 to strike the staple 16 in the staple launching path 3 and the staple leg 16a.
Is punched into the adherend 25 from the opening. By the way, on the opening side of the staple driving path, a part of both side surfaces 13b of the staple leg regulating member 13 closes the inside of the staple legs 16a in the staple driving path 3. The staple legs 16a are surrounded on three sides by the wall of the staple launching path 3 and the other is supported by the side surface of the staple leg regulating member 13 (see FIGS. 4 and 5). 25, and after being penetrated, bent by the clincher 2 to complete the operation. When the staple 16 slides, the staple 16
When the back of the staple 16 comes into contact with the inclined surface 13a of the staple leg regulating member 13, the staple 16 retreats against the compression spring 18.
Is allowed.

Thereafter, when the force on both handles is released and the movable handle 9 is returned to the original position, the slider 6 returns and the staple magazine 7 is moved by the spring force of the resilient spring 20 and the function of maintaining the interval between the connecting rods 21. Also move back.

[0014]

According to the driving tool described above, the slider is driven by the toggle mechanism based on the operation of the fixed handle and the movable handle, and the staple is driven by the driver integrally with the slider. Strong driving force can be obtained by operation.

In addition, since the staple is ejected after the staple magazine clamps the adherend with the clincher via the resilient spring by driving the slider, the staple is moved in the initial stage of the driving. It can be securely fastened.
