Then, a state is obtained in which resistance against rotation to is given. Therefore, the pressing portion 61 of the upper cover 55
The lower end of the handle 19 is kept in a state of being substantially in contact with the top wall 33 without wobbling, so that an operation force for pushing down the upper cover 55 is immediately transmitted to the handle 19 to obtain good responsiveness.

Here, the binding needles 14 in the frame 16
When a new binding staple is loaded by consuming the upper cover 55, the upper cover 55 may be rotated in a direction in which the upper cover 55 is greatly opened with respect to the base cover 56. When the upper cover 55 is rotated, the hook portion 70 of the upper cover 55 is configured to be hooked on the lower end of the hanging wall 34 of the handle 19, so that the rib 34 </ b> A provided on the hanging wall 34 The engagement with the stopper rib 24B is released and the stopper rib 24B rotates together with the upper cover 55 (FIG. 22).
reference). Therefore, since the slider 29 in the frame 16 has one end of the connection band 43 fixed to the handle 19 side, the slider 16 in the frame 16 resists the force of the coil spring 31 described above.
, So that a new binding needle 14 can be loaded.

The slider 29 can be removed from the guide shaft 28 using a flathead screwdriver or the like, and the second end 43C of the connecting band 43 can be pulled out from the hole 41 on the handle 19 side. Only the resin parts can be removed from the metal stapler body 11.

Next, the principle of reducing the operation force of the stapler 10 will be described. As shown in FIG. 24, the handle 19 and the base 2 constituting the stapler body 11 are used.
The center of relative rotation 1 is at the position of the shaft pin 50, and is located behind the center position of the protruding shaft 65, which is the center of relative rotation between the upper cover 55 and the base cover 56. The contact position between the pressing portion 61 and the top wall 33 of the handle 19 is determined by a protruding shaft 65.
More forward. Therefore, assuming that the operation force required for the conventional stapler, that is, the binding load, is 10 kg, the distance L1 between the rotation center of the stapler main body 11 and the position of the front wall 59 of the upper cover 55 is 102 mm, and the rotation center and the pressing force are pressed. The distance L2 from the tip of the portion 61 is 2
3 mm, the distance L3 between the center of rotation of the cover 12, that is, the center of the protruding shaft 65, and the tip of the pressing portion 61 is 11 mm,
Further, when the distance L4 between the rotation center of the cover 12 and the point where the binding load P1 is applied is 70 mm, the binding load P2 required at the tip of the pressing portion 61 is P2 = 1 kg × 102 mm ÷ 23 = 23. .46 kg.
Therefore, the binding load P1 required at the tip of the upper cover 55 is P1 = 23.46 kg × 11 mm ÷ 70 = 3.68 kg. As is clear from the above, in the configuration of the present embodiment, it is possible to greatly reduce the operating force as compared with the related art.

The structure of the slider 29 according to the present invention is not limited to the illustrated example as long as it is detachable from the frame, and the design may be changed arbitrarily. However, adopting the configuration of the embodiment is advantageous in that the structure can be made extremely simple.

[0035]

As described above, according to the present invention,
Since the slider for pushing the binding needle forward is provided detachably with respect to the frame, while the frame is made of metal, when the slider is made of resin, it is easy to separate them from each other, and they are separated and discarded. Can be thoroughly enforced.

When the slider is detachably provided on the guide shaft supported in the frame,
A slider attachment / detachment structure can be realized with only a slight design change while utilizing the structure of an existing product.

Further, in a configuration in which the slider has a guide shaft passage and a slot groove connected to the passage and opened to the lower surface side, the guide shaft is positioned in the slot groove when the slider is mounted. Since it is sufficient to push the slider, the mounting work of the slider can be performed extremely easily, and the slider can be easily removed.

In a configuration in which a connecting band is provided between the slider and the handle and the connecting band is detachably provided on the handle, the connecting band can also be removed. It is possible to do.
