Abstract

The utility model provides a labor-saving stapler, which comprises a first pressure arm, a link arm group, a pedestal and a base, wherein the proper position of the middle section of the first pressure arm is provided with a corresponding guide way groove; the link arm group comprises a second pressure arm and a third pressure arm; staples are received in the pedestal; a bedframe is arranged above the base, and is provided with a first hole, a second hole and a pedestal hole which can be pivoted correspondingly. With the components, when the lip of the first pressure arm is pressed, the lever force from a force point to a pivoted position of a pressure arm rotating shaft of the bedframe is larger than the lever force from a guide way rotating shaft to the pivoted position of the pressure arm rotating shaft of the bedframe, so the pivoted second pressure arm can be driven to actuate; then, a connecting rod fulcrum and the second pressure arm form an unequally spaced pivoted linking so as to link the third pressure arm to perform warping actuation; and final force can be transferred to a staple supporting plate to press the staple downwards for binding, thereby forming a stapler in labor-saving pressing.

Description

Labor-saved stapler

Technical field

The utility model refers to a kind of stapler structure that utilizes lever principle to reach the laborsaving bookbinding operation of paper especially relevant for a kind of labor-saved stapler.

Background technology

The induction-arrangement of general paperwork and profile all can utilize stapler that its paper or files are directly ordered and close, and is scattered to avoid the messy of files, can make things convenient for the bookbinding and the harvesting of archives, so stapler is the favourable helper of an archive arrangement in fact.

See also shown in Figure 5ly, be the structure of general known stapler, this stapler 7 mainly comprises: base 71, needle tray seat 72, pressure arm 73; This needle tray seat 72 is installed with the nail pin and axle is established the pivot hole 74 that is socketed on base 71 1 sides, and pressure arm 73 is sleeved on this needle tray seat 72 and establish socket with 74 in the pivot hole of base 71, and front end is combined with a needle jack-up piece 75; The user is by pushing this pressure arm 73, rotating shaft 76 with pivot hole 74 is the fulcrum rotation, the needle jack-up piece 75 downward starts of these pressure arm 73 front end combinations of stopper simultaneously, to press nail pin that this needle tray seat 72 is installed with vertically downward, and on the needle plate 77 of base 71 front ends, bend combination, realize the function of files bookbinding.
