Embodiment 1

[0080] like figure 1 and 2 As shown, the stapler according to the first embodiment of the present invention includes a base member 1 in which staples S are stored (see image 3 ), has a driver unit 30 for pushing the staples S stored in the staple cartridge 2 to bind the bundle of paper (not shown), applies the force for binding the bundle of paper to the driver unit 30 through the internal handle 3 The external handle 4 of the operating force, and the interlock mechanism 5 for interlocking the internal handle 3 and the external handle 4 (see image 3 ). The outer surface (ie, the upper surface and the side surface) of the outer handle 4 is covered with a handle cover, that is, a resin cover 41 .

[0081] reference together image 3 , the base member 1 is a base that rotatably supports the rear end 2a of the nail cartridge 2 and the rear end 3d of the inner handle 3 by the first support member 6 using the same shaft, and also utilizes the second support member on the rear...

Embodiment 2

[0133] Figure 14 is a perspective view of a stapler according to a second embodiment of the present invention, and Figure 15 is a longitudinal sectional view of the stapler. exist Figure 14 and 15 In , reference numeral 1 denotes a base member. A binding stand 11 on which a bundle of paper is placed is formed on the front side of the base member 1 , and a magazine guide 11 e and a handle support plate 11 f stand at the rear end of the base member 1 . The cartridge 2 and the inner handle 3 are rotatably supported by the first support member 6 provided in the cartridge guide 11e. Furthermore, the outer handle 4 for operating the inner handle 3 is rotatably supported by the second support member 7 provided in the handle support plate 11f.

[0134] The staple cartridge 2 has a space in which the connected staples S are stored, and a push-out portion 28 is formed at the front end of the staple cartridge 2 . Further, a push rod 26 for pushing the connected staples S toward t...

Embodiment 3

[0159] Figure 21 is a perspective view of a stapler according to a third embodiment of the present invention, and Figure 22 is a longitudinal sectional view of the stapler. Descriptions of features substantially the same as those of the stapler according to the first and second embodiments are omitted.

[0160] According to the third embodiment, the base 1 a of the base member 1 made of metal is covered with the base covering member 60 made of synthetic resin. Accordingly, the staple groove 11 d is provided and fixed on the cartridge guide 11 e provided under the base cover member 60 .

[0161] That is, if Figure 23 As shown, the cartridge guide 11e is a metal member having a U-shaped cross section and has standing walls 61 on both sides of one end (rear end) thereof, and the standing walls 61 have a large height. Also, a cartridge guide 11e is fixed on the upper surface of the base 1a in the longitudinal direction. Support the first support member 6 of nail box 2 and ...

Abstract

A stapler includes a U-shaped handle, a driver unit coupled to the front end of the handle, and a magazine in which staples are stored. The driver unit includes a driver plate secured to the front of the driver holder. The rear of the handle and the rear of the magazine are concentrically and pivotally connected. Arms each protruding from respective sides of the driver holder are movably inserted into respective engagement holes formed on each of the side plates of the handle. When the handle is initially depressed, the rear upper portion of the driver retainer contacts the upper inner surface of the handle such that the front end of the driver plate slopes toward the front side of the magazine.

Description

technical field [0001] The invention relates to a stapler. Background technique [0002] A stapler is known in which the outer handle and the inner handle have different pivots at their ends and can be rotated separately. The two handles are locked and connected to each other by a connecting part to form a force amplification mechanism. The force-increasing effect produced by this interlocking connection structure reduces the operating force for binding paper bundles (see, for example, JP-A-2005-138248 (page 9, Figure 15 ) and JP-A-2005-138247 (p. 4, Figure 15 )). [0003] Although this stapler is a medium or large stapler, like a regular stapler, it has a driver plate set to the inner handle. Also, when the driver plate is operated so as to pass through the front end portion of the staple cartridge provided under the inner handle, the frontmost staple of the connected staples stored in the staple cartridge is pushed out to staple the paper bundle. [0004] In a medium-...
