The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further:

As shown in the figure, the purpose of this stapler is in order to improve the thickness of bound document, to reduce applied force thereby increase bookbinding power.

This stapler is mainly by the plastic cement base, needle plate, laborsaving presser, needle propeller, connecting rod, needle tray and handle etc. are partly formed, wherein be fixed with five metals support 23 in the base 9, its front end is equipped with needle plate 8, the afterbody of five metals support 23 is fixed with a rotating shaft 15, its front end punching press has a laborsaving pivot point 22, rotating shaft 15 is hinged with the afterbody of eedle presser 3, front end at eedle presser 3 is fixed with shell fragment 4 by shell fragment rivet 2, end face at eedle presser 3 has two grooves, in this groove, be fixed with protruding frame and buckle piece 18, the hole 212 that is inserted with laborsaving lever shaft 19 in the piece 18 and passes laborsaving lever plate two sides at button connects laborsaving lever plate and eedle pressers, the end face of buckleing the eedle presser 3 of piece 18 back at protruding frame also has a square opening, the shape approximation of laborsaving lever plate 21 is in a right angled triangle, right-angle side is last, hypotenuse is following, inferior horn at hypotenuse is interior circular arc barb 211, fixed-site at the right angle has two elastic braking plates arranged side by side 17, there is the flange 171 of projection the side of this brake(-holder) block 17, barb 211 hooks are solid on laborsaving pivot point 22, brake(-holder) block 17 is connected in the square opening of eedle presser 3 end faces by flange 171, control the position of laborsaving lever plate and handle, at laborsaving lever plate 21 outside suit upper handles 1, butt joint bonnet 16 in handle 1 back becomes complete stapler.

Operation principle

Laborsaving principle: by a laborsaving lever plate is set on order pin mechanism eedle presser, and between laborsaving lever plate and eedle presser, be provided with the laborsaving fulcrum of laborsaving lever shaft and five metals support front end, utilize lever principle, increase kinetic moment, reduce the moment of resistance, realized active force under identical situation, bookbinding power is multiplied, and has overcome the existing stapler hypodynamic problem of stapling together preferably.

Be provided with the bayonet fittings that is provided with on brake(-holder) block and the eedle presser in laborsaving lever plate rear end, thus the position of joystick is renovated time rotation.During bookbinding, the subordinate handle of pressing, laborsaving lever plate serves as that fixed point drives laborsaving lever shaft rotation with laborsaving fulcrum, causing laborsaving lever shaft to push down eedle presser is that the center of circle down rotates and becomes balance pivot with the rotating shaft, form the kinetic moment (point of application is to the distance of laborsaving lever shaft) and the moment of resistance (laborsaving fulcrum is to the distance of laborsaving lever shaft), kinetic moment equals the twice of the moment of resistance.As shown in drawings, thus realize laborsaving 50 percent effect (lever principle).

Braking principle: when the dress pin is renovated, handle is upwards swing of the center of circle with laborsaving lever, if being contained in the brake(-holder) block of laborsaving lever plate rear end inserts in the bayonet socket on the eedle presser, the eedle presser lower surface is blocked on brake(-holder) block flange top, makes that laborsaving lever plate can not rotate with handle again when the barb of laborsaving lever plate and the laborsaving fulcrum on the support are just thrown off.When ordering pin, brake(-holder) block is thrown off bayonet socket, and the eedle presser upper surface is withstood in brake(-holder) block flange bottom, and the position that the pin back handle rises and rotates because of return elastic force is ordered in control.

The above; be better embodiment of the present utility model; only be that the utility model is set forth and illustrated; be not limited to disclosed any concrete form; the technical solution of the utility model retouched or be equal to replace and, also should be considered as protection domain of the present utility model in the application in other field.
