Technical field

The present invention relates to office appliance fields, and in particular, to a kind of pressure lever type nail puller.

Background technique

Stapler is widely used in office process, and brings very big convenience for office, but in bookbinding It inevitably will appear in the process and bind wrong or not stapled phenomenon, we just need to bind these when encountering such case The nail of mistake is extracted, in general people all can directly with hand go to deduct come or with easy tool by nail pull out come, but This mode is not only difficult to extract the staple of those mistakes, but also there are also the damages that greatly may cause hand, although city There are also nail pullers on, but use very laborious.

Summary of the invention

The object of the present invention is to provide a kind of pressure lever type nail pullers, and the pressure lever type nail puller is time saving and energy saving, and work efficiency is high, Safety coefficient is high.

To achieve the goals above, the present invention provides a kind of pressure lever type nail puller, including pedestal, reset spring, knife rest, Axle sleeve, first connecting rod, short axle, second connecting rod, compression bar, long axis, short screw, magnet block and nail nipping knife；Wherein,

Compression bar is fixed on the base by long axis, and one end of compression bar directly sticks into the slot of second connecting rod, second connecting rod One end is connected on pedestal by short axle, and the other end is connected with first connecting rod by short axle, and the other end of first connecting rod passes through Short axle is connect with axle sleeve, and axle sleeve is fixed on knife rest by short screw, and reset spring is fixed on knife rest between end and pedestal, magnetic Iron block is embedded on nail nipping knife, is used and is threadedly coupled between nail nipping knife and knife rest.

Preferably, knife rest includes a pair of of the secondary bar for being located in the middle mobile jib and mobile jib two sides, and axle sleeve is arranged and is fixed on pair On bar, reset spring is set in outside mobile jib, also, nail nipping knife is arranged in mobile jib bottom end.

Preferably, the manual end surfaces of compression bar are equipped with a plurality of anti-skidding raised line.

Preferably, the slot on second connecting rod is strip sliding slot and extends along the length direction of second connecting rod.

Preferably, the slot on first connecting rod is strip sliding slot and extends along the length direction of first connecting rod.

Preferably, pedestal is made of metal material, and first connecting rod, short axle, second connecting rod and compression bar are made of plastics.

According to the above technical scheme, compression bar is fixed on the base by the present invention by long axis, and one end of compression bar directly sticks into In the slot of second connecting rod, one end of second connecting rod is connected on pedestal by short axle, and the other end passes through short axle phase with first connecting rod The other end of connection, first connecting rod is connect by short axle with axle sleeve, and axle sleeve is fixed on knife rest by short screw, and reset spring is solid It is scheduled between knife rest upper end and pedestal, magnet block is embedded on nail nipping knife, is used and is threadedly coupled between nail nipping knife and knife rest.It uses When, nail nipping point of a knife mouth is inserted between staple and the surface for being bound file, compression bar is grasped and the pushing that exerts a force is extracted and ordered Staple.At this point, unclamping compression bar, reset spring resets, and device returns to original state, finally removes the staple being pulled out.

Other features and advantages of the present invention will the following detailed description will be given in the detailed implementation section.

Specific embodiment

Below in conjunction with attached drawing, detailed description of the preferred embodiments.It should be understood that this place is retouched The specific embodiment stated is merely to illustrate and explain the present invention, and is not intended to restrict the invention.

In the present invention, in the absence of explanation to the contrary, the noun of locality that " upper and lower, inside and outside " etc. is included in the term Only represent orientation of the term under normal service condition, or be those skilled in the art understand that be commonly called as, and be not construed as pair The limitation of the term.

Referring to Fig. 1 and Fig. 2, the present invention provides a kind of pressure lever type nail puller, including pedestal 1, reset spring 2, knife rest 3, axis Set 4, first connecting rod 5, short axle 6, second connecting rod 7, compression bar 8, long axis 9, short screw 10, magnet block 11 and nail nipping knife 12；Wherein,

Compression bar 8 is fixed on pedestal 1 by long axis 9, and one end of compression bar 8 directly sticks into the slot of second connecting rod 7, and second connects One end of bar 7 is connected on pedestal 1 by short axle 6, and the other end is connected with first connecting rod 5 by short axle 6, first connecting rod 5 The other end is connect by short axle 6 with axle sleeve 4, and axle sleeve 4 is fixed on knife rest 3 by short screw 10, and reset spring 2 is fixed on knife rest Between 3 upper ends and pedestal 1, magnet block 11 is embedded on nail nipping knife 12, is used and is threadedly coupled between nail nipping knife 12 and knife rest 3.

In the present embodiment, in order to optimize the mechanical structure of knife rest 3, it is preferable that knife rest 3 includes being located in the middle mobile jib With a pair of of secondary bar of mobile jib two sides, axle sleeve 4 is arranged and is fixed in secondary bar, and reset spring 2 is set in outside mobile jib, also, rises Knife 12 is followed closely to be arranged in mobile jib bottom end.

When using the pressure lever type nail puller, hand skids during pushing in order to prevent, and depression is caused to fail, excellent The manual end surfaces of selection of land, compression bar 8 are equipped with a plurality of anti-skidding raised line.

In addition, sliding adjustment and rotation for the ease of double link, the preferably slot on second connecting rod 7 is strip sliding slot and edge The length direction of second connecting rod 7 extends.

Likewise, the slot on first connecting rod 5 is strip sliding slot and extends along the length direction of first connecting rod 5.

In order to while mitigating the pressure lever type nail puller overall weight improve use process in stability, avoid its by It is easy skew after power even to topple over, it is preferable that pedestal 1 is made of metal material, first connecting rod 5, short axle 6,7 and of second connecting rod Compression bar 8 is made of plastics.

Through the above technical solutions, compression bar 8 is fixed on pedestal 1 by the present invention by long axis 9, one end of compression bar 8 is direct It sticks into the slot of second connecting rod 7, one end of second connecting rod 7 is connected on pedestal 1 by short axle 6, and the other end and first connecting rod 5 are logical It crosses short axle 6 to be connected, the other end of first connecting rod 5 is connect by short axle 6 with axle sleeve 4, and axle sleeve 4 is fixed on knife by short screw 10 On frame 3, reset spring 2 is fixed between 3 upper end of knife rest and pedestal 1, and magnet block 11 is embedded on nail nipping knife 12, nail nipping knife 12 with Using threaded connection between knife rest 3.In use, 12 sharp-crested of nail nipping knife is inserted between staple and the surface for being bound file, It grasps compression bar 8 and staple is extracted in the pushing that exerts a force.At this point, unclamping compression bar 8, reset spring 2 resets, and device returns to original state State finally removes the staple being pulled out.In this way, staple can be pulled up with labour-saving, and service efficiency is high；Axle sleeve position It is adjustable, it is matched with the positive stop lug boss on knife rest, can control the motion amplitude of nail puller；Structure is simple, and manufacturing process is simple, It is at low cost；It is easy to operate, it is suitable for majority of populations；Rise and order on knife embedded with magnet, avoidable staple disperses, safety coefficient compared with It is high；Compact structure is easily placed when not used, saves space；Nail nipping knife is interchangeable and install convenient, substantially increases making for staple remover Use the service life.
