Technical field

The utility model relates to a kind of office stationary, and more particularly, the utility model relates to a kind of stapler.

Background technology

Energy-storage book is to utilize elastic component (as spring, leaf spring, torsion spring etc.) energy storage, and abrupt release energy stored then drives and to order faller gill moment impact book pin, realizes that high energy orders the function of pin, and it has laborsaving, orders advantages such as pin is effective.But a known class energy-storage book such as China Patent No. is at present: all there is a common defective in the stapler of ZL94215495.9: its idle state is down because order faller gill all in the chamber front lower ends, so stop that the book pin is front loaded from chamber.For a long time, all do not solve this class stapler ejects the dress pin from the chamber front end structure problem, can only adopt the relatively poor book pin mode of packing into from stapler chamber afterbody or bottom, though thereby the consumer enjoys energy-storage book nail pin labour-saving advantage, but can't use needle tray to eject the benefit that dress book pin brings from stapler chamber front end.Well-known book needle tray ejects the advantage of dress book pin from stapler chamber front end: dress book pin and to change the book pin convenient, fast, dress book pin is effective.And the shortcoming of the book pin mode of packing into from stapler afterbody or bottom is: dress book pin and to change the book pin all inconvenient, not quick, the easy pin of falling book when dress looses book pin or a small amount of several book pins, the difficult dress; Fetch inconvenience when changing the book pin, dress book pin is of low quality.

The contrast China Patent No. is: 2006100634464 stapler, this stapler also is that the book needle tray ejects dress book pin from front end, with the difference of the structure of the application's patent be: this stapler order faller gill when idle state, be positioned at the chamber upper front end, and be positioned at the top of book needle tray, so its book needle tray can eject the dress pin, can not eject with the book needle tray but order faller gill.This class is ordered the stapler shortcoming that faller gill is positioned at the top of book needle tray:

1) after each bookbinding is finished, needs power upwards will order faller gill and be promoted to the chamber upper front end, abdicate and adorn the required access way of book pin next time;

2) finish ordered pin last time after, after the spared book pin under the thrust of elasticity needle propeller, automatically be pushed to book needle tray front end forward, preparation acceptance is ordered the impulsive force of faller gill and is ordered pin, does not also put on and just in time is clamped between spared book pin and the book needle tray front end face but order faller gill this moment.Both of these case all needs upwards power will order faller gill to be promoted to the chamber upper front end.The latter particularly, when after filling the book pin, binding, be promoted to the chamber upper front end if will order faller gill, because rectangular book pin compresses the spring of elasticity needle propeller in a large number, the bigger active force of elasticity needle propeller generation affacts to be ordered on the faller gill, and will order faller gill with book needle tray front end medial surface and clamp, producing bigger frictional force stops and orders the faller gill lifting that makes progress, so correspondingly just needing special top spring to produce big strength upwards promotes, because the top spring force that adopts when producing in batches can not very accurately be controlled, that adds the power transmittance process will overcome various resistances, so all the top spring force can be done more when producing in batches.So the hand during bookbinding can need bigger power bound book pin.Do like this in the actual production, the faller gill of ordering of the patent stapler of our current application does not need when idle state and will order above the front end that faller gill rises to chamber, so the top spring force can be done forr a short time, so bookbinding is more laborsaving yet.

3) former China Patent No. is: 2006100634464 staplers of being done, it orders faller gill when idle state, when being positioned at the chamber upper front end, the laborsaving lever of energy storage device and spring more lean on away from the chamber bottom, stapler can only do more, the arm of force ratio of laborsaving lever is difficult to rationally, and arm of force labour-saving ratio is done forr a short time, and stapler can not be done more laborsavingly.For example when actual production, bind 25 paper of 24/6 book pin of standard with the stapler of same specification: common stapler is ordered needle force and is about 13 kgfs; China Patent No. is: 2006100634464 staplers of being done were about for 50% (the actual needle force of ordering is about the 6-7 kgf) than common stapler is laborsaving.
