Description

The present invention relates to a stapler, and more particularly to a stapler having a leg flattening function and an anvil guiding device for stably moving the anvil.

In order to improve the stapler effect, the conventional stapler has a leg flattening device for flattening the stapler leg to prevent the stapler leg from being injured by the person and the document being damaged. The leg flattening device has an anvil element for flattening the stapler legs, and the conventional stapler anvil element is fixed on a conventional stapler support. However, there is a gap between the conventional fixed anvil element and the stapler, and the gap tends to lower the leg flattening effect.

Another type of conventional leg flattening device has a slidable anvil element to solve the problems caused by fixed anvil elements. However, the conventional stapler cannot provide a support effect to the slidable anvil element, and the slidable anvil element tilts easily, thereby reducing the leg flattening effect.

Referring to FIG. 5, the conventional stapler has a support base (90) and a slidable anvil element (92). The support base (90) has two guide grooves (902) defined on opposite sides of the support base (90). The anvil element (92) is movably attached to the support base (90) and has an upper portion, two sides and two shoulders. The upper part is used to secure the stapler legs and acts as a functional part (924). The side surfaces are each attached to the guide groove (902) and have a wider width than the top portion to form a shoulder. The sides and shoulders act as non-functional parts (922). The guide groove (902) allows the anvil element (92) to slide stably during the stapler leg flattening process.

However, the conventional stapler has the following drawbacks.
1. The non-functional portion (922) of the anvil element (92) is not fully attached to the guide groove (902) and is partially exposed therefrom. The movement of the anvil element (92) is easily affected. For example, the anvil element (92) is blocked by the object at a position between the non-functional portion (922) and the corresponding side of the support (90), causing an unstable movement of the anvil element (92). .

2. The anvil element (92) must be held wide enough in the guide groove (902) on the side of the support base (90), or the support base (90) fits the width of the anvil element (92). Enough width. Thus, the dimensions of the other stapler elements are thereby limited, and the staple design range is also limited.

To overcome these drawbacks, the present invention seeks to provide a stapler to alleviate or eliminate the above problems.

A main object of the present invention is to provide a stapler having a leg flattening function and an anvil guiding device for stably moving the anvil.

The stapler includes a support base, a cartridge assembly unit, an activation assembly unit, a leg flattening device, and a rail assembly unit. The support base has a bottom. The cartridge assembly is pivotally connected to the support base. The activation assembly is pivotally connected to the support base. The leg flattening device is mounted on a support base and has a moving base and an anvil element. The moving table is operably connected to the support table and has an anvil hole defined through the moving table. The anvil element is movably attached to the anvil hole of the moving table and has a functional part and a non-functional part movably attached to the anvil hole. The rail assembly is mounted on the bottom surface of the support base and includes at least one rail bracket projecting therefrom and projecting from the bottom surface of the support base. Each of the at least one rail bracket has a rail to which a non-functional portion of the anvil element is slidably mounted.

Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

The support table (10) has a bottom surface (12) and two side surfaces (14), and includes a lower table (102) and an upper table (104). The lower platform (102) is plastic and has a U-shaped cross section for forming a bottom surface and two side surfaces. The bottom surface and side surface of the lower base (102) act as the bottom surface (12) and side surface (14) of the support base (10), respectively. The upper platform (104) is metal and is attached to the lower platform (102) and has a U-shaped cross section. The cartridge assembly section (20) is pivotally connected to the support base (10) and holds the stapler inside. The starter assembly (30) is pivotally connected to a support (10) on the cartridge assembly (20). The leg flattening device (40) is mounted on the support base (10) and has a moving base (41) and an anvil element (42). The moving table (41) is operatively connected to the support table (10) and has an anvil hole (412) defined through the moving table (10). The anvil element (42) is movably attached to the anvil hole (412) of the moving platform (41), is supported by a spring, and has an upper portion, two sides and two shoulders. The upper part of the anvil element (42) is movably attached to the anvil hole (412) and is used to secure the staple legs and acts as a functional part (424). The sides of the anvil element (412) have a wider width than the top to form a shoulder. The sides and shoulders are not used to secure the staple (80) legs, but act as non-functional parts (422). Since the support base (10), the cartridge assembly (20), the starter assembly (30), and the leg flattening device (40) are conventional, detailed structural details of these elements are omitted.

The rail assembly (50) is mounted on the bottom surface (12) of the support base (10), protrudes therefrom and includes at least one rail bracket (52). At least one rail bracket (52) is mounted on the support base (10), protrudes therefrom and is separated from the side surface (14) of the support base (10). In the preferred embodiment, the rail assembly (50) has two rail brackets (52). Each rail bracket (52) has a rail (54) to which a non-functional portion (422) of the anvil element (42) is slidably mounted, and the rails (54) of the rail bracket (52) are aligned with each other. . Each rail bracket (52) is composed of a plurality of struts (522) separated from each other to define a rail (54) between the struts (522). In the preferred embodiment, each rail bracket (52) consists of two struts (522) arranged in parallel, or three struts (522) arranged in a triangular shape.

With reference to FIGS. 1, 3 and 4, when the activation assembly (30) is pushed, the activation assembly (30) releases one of the staples (80) from the cartridge assembly (20). Turn to the side. The released staple (80) legs extend through the stapled material and strike the functional part (424) on the anvil element (42) exposed from the anvil hole (412) of the moving platform (41). Accordingly, the functional portion (424) of the anvil element (42) bends and secures the legs of the released stapler (80), and the anvil (42) is lowered along the rails of the rail assembly (50). Move to. The activation assembly (30) bends and secures the legs of the released stapler (80) and the anvil (42) moves down along the rails of the rail assembly (50). When the activation assembly (30) is released, the anvil element (42) can be moved to its original position along the rail (54) with the force provided by the spring.

Due to the movement of the anvil element (42), the slidable anvil element (42) can solve the problems of the conventional fixed anvil assembly due to the gap between the stapler and the fixed anvil element. The arrangement of the rail assembly (50) stabilizes the anvil element (42) along the rail (54) of the rail assembly (50) so that the operation of the stapler and the leg flattening effect are improved. Can move.

Furthermore, since the non-functional part (422) of the anvil element (42) is covered with and below the moving base (41), only the functional part (424) is located in the anvil hole (412) of the moving base (41). ) To be exposed. The object is kept in a position between the non-functional part (424) of the anvil element (42) and the side surface (14) of the support base (10) so that the movement of the anvil element (42) is not affected or prevented. Not. Furthermore, the non-functional part (422) of the anvil element (42) is separated from the side surface (14) of the support base (10) and is held by the rail (54) of the rail bracket (52) away from it. The widths of the anvil element (42) and the support base (10) are not limited to each other. Therefore, the dimensions of the other stapler elements are not limited, and the design range of the stapler is expanded and becomes universal.
