Description
Technical field
The present invention relates to a kind of office stationary, more particularly, the present invention relates to a kind of stapler.
Background technology
The advantages such as energy-storage stapler is to utilize elastic component (as spring, leaf spring, torsion spring etc.) energy storage, and then the energy of abrupt release storage, drive staple driving plate moment impact book pin, realizes the function of high energy nail pin, and it has laborsaving, and the nail pin is effective.But a known class energy-storage stapler such as China Patent No. is at present: the stapler of ZL94215495.9 (publication number CN2194267Y), all have a common defective: under its idle state because staple driving plate 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 and eject the structure problem of dress pin from the chamber front end, 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 stapler nail pin labour-saving advantage, but can't use needle tray to eject from stapler chamber front end the benefit that dress book pin brings.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 the loose book pin of dress 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: the stapler of 2006100634464 (publication number CN1948022A), this stapler is also that the book needle tray ejects dress book pin from front end, with the structure difference of the application's patent be: the staple driving plate of this stapler is 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, but staple driving plate can not eject with the book needle tray.The stapler shortcoming that this class staple driving plate is positioned at the top of book needle tray is:
1) after each bookbinding is completed, need power upwards that staple driving plate is promoted to the chamber upper front end, abdicate and fill the required access way of book pin next time;
2) complete followed closely pin last time after, after the spared book pin under the thrust of elasticity needle propeller, automatically be pushed to forward book needle tray front end, prepare to accept the impulsive force nail pin of staple driving plate, but staple driving plate do not put on also and just in time was clamped between spared book pin and book needle tray front end face this moment.Both of these case all needs power upwards that staple driving plate is promoted to the chamber upper front end.the latter particularly, when binding after filling the book pin, if staple driving plate is promoted to the chamber upper front end, because rectangular book pin compresses the spring of elasticity needle propeller in a large number, the elasticity needle propeller produces larger active force and is applied on staple driving plate, and together with book needle tray front end medial surface, staple driving plate is clamped, produce larger frictional force and stop the staple driving plate lifting that makes progress, so correspondingly just needing special top spring to produce larger strength upwards promotes, the top spring force that adopts during due to batch production 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 during batch production.So the hand during bookbinding can need larger power bound book pin.Do like this in actual production, we do not need staple driving plate is risen to above the front end of chamber when idle state by the staple driving plate of the current patent stapler of applying for yet, so the top spring force can be done littlely, so bookbinding is more laborsaving.
3) former China Patent No. is: 2006100634464 staplers of doing, its staple driving plate is 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 littlely, 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 needle nailing force is about 13 kgfs; China Patent No. is: 2006100634464 staplers of doing were about for 50% (actual needle nailing force is about the 6-7 kgf) than common stapler is laborsaving.
