In the present embodiment, handle 5 belows also are provided with storage power shell fragment 1 and return shell fragment 2, the both sides, rear end of storage power shell fragment 1 are respectively equipped with in the locating hole that inwall that outwardly directed positioning convex 15,16, two positioning convex 15,16 are rotatably mounted in two

side covers

6,7 respectively is provided with.The front end of storage power shell fragment 1 is provided with one and connects neck, and this connection neck is provided with presses nail sheet 4 and discharge return shell fragment 3; Return shell fragment 2 is positioned at storage power shell fragment 1 below, and its both sides are individually fixed on the inwall of two side covers 6,7.Be equipped with one on storage power shell fragment 1 and the return shell fragment 2 and stretch to the free end of pressing nail sheet 4.Discharge return shell fragment 3 and press nail sheet 4 tops to be respectively equipped with the through hole that is used to be set in the connection neck on the storage power shell fragment 1, and press nail sheet 4 to be positioned at the inboard that discharges return shell fragment 3.The free end of return shell fragment 2 is upturned.Storage power shell fragment 1 is buckled 8 by drag hook and is fixed on the handle 5, be specially drag hook and buckle 8 and be set in the free end that storage power shell fragment 1 is provided with, and drag hook is buckled 8 and is positioned at the inboard of pressing nail sheet 4.Discharge return shell fragment 3 and be provided with a free end to its outside perk, this free end contacts with the inwall of two side covers, 6,7 front end buckling surfaces; The two bottom sides that discharges return shell fragment 3 is respectively equipped with

chimb

31,32, two

chimbs

31,32 and rotatably inserts in the mating holes that the inwall that is installed on two side covers 6,7 is provided with.

In the present embodiment, handle 5 front inner wall also are provided with tip wedge 51 down, and these wedge 51 tips are provided with the inclined-plane that surpasses laterally, and correspondingly, the inside top that discharges return shell fragment 3 is provided with an acting surface relative with this inclined-plane.This acting surface is in tilted layout, and incline direction is identical with the inclined-plane that wedge 51 is provided with.The clasp nail assembly also comprises ejector pin frame 9, and ejector pin frame 9 is fixedly installed on the base 13.The rear portion of ejector pin frame 9 and base 13 snappings, mid portion insert by positioning piece and are fixed on the base 13; Also be provided with the stage clip 9 of reset response between base 13 rear portions and the ejector pin frame 9.The front end of ejector pin frame 9 is provided with nail pushing plate 10, and the sidewall of ejector pin frame 9 is provided with the extension spring 11 that is used for fixing nail pushing plate 10; Base 13 front ends are provided with pintle plate 12, pintle plate 12 with press nail sheet 4 over against.

Operation principle of the present utility model is as follows:

During original state, the connection neck of storage power shell fragment 1 is inserted in the through hole that discharges return shell fragment 3 tops.

During work, depress handle 5, handle 5 acts on the free end in the storage power shell fragment 1, and make it descend compressive strain, at this moment, the datum plate of storage power shell fragment 1 free end both sides also begins to be bent downwardly distortion, the connection neck of storage power shell fragment 1 and the angle a that discharges between the return shell fragment 3 diminish, and can draw according to triangle relation, to discharging the pressure f 1=F * COSa of return shell fragment 3, F is that 1 pair on storage power shell fragment discharges the downward active force of return shell fragment 3, when the F increase, angle a diminishes, and COSa numerical value increases, then 1 one-tenth how much multiplication of pressure f is referring to Fig. 3.When pressure f 1 when discharging the elastic force f2 of return shell fragment 3, storage power shell fragment 1 will be along the distortion of pressure f 1 direction, at this moment, the connection neck of storage power shell fragment 1 is thrown off and is discharged return shell fragment 3.If because of each parts variation build-up of pressure f1 can not be when discharging the elastic force f2 of return shell fragment 3, then the inclined-plane contact that is provided with of wedge 51 tips of handle 5 front ends discharges the tilting action face that return shell fragment 3 is provided with, because of the stressed reason generation component to the right in inclined-plane, force to discharge the connection neck that return shell fragment 3 is thrown off storage power shell fragments 1.Storage power shell fragment 1 is being released in a flash, and is being with and is pressing nail sheet 4 high speed impact staples, finishes the nailing action, and nail collides pintle plate 12 back upsets, execution after passing paper.The storage power shell fragment 1 of this moment is in lowest point, referring to Fig. 5.

After finishing the stapling action, decontrol handle 5, the free end of return shell fragment 2 impels upwards return of storage power shell fragment 1 at this moment, because of fixing by its positioning convex 15,16 at the rear portion of storage power shell fragment 1, therefore, the connection neck of storage power shell fragment 1 is that the circumference that the center of circle is done to make progress rotatablely moves with positioning convex 15,16, when getting back to vertex position, referring to Fig. 6, the connection neck of storage power shell fragment 1 is just in time aimed at the lead to the hole site that discharges return shell fragment 3 tops, discharge return shell fragment 3 and be returned to initial position under the elastic force effect, whole action is finished.

When needs are put into staple 17, draw back base 13 front ends to the back lower place, referring to Fig. 7, at this moment, whole clasp nail assembly withdraws from a main body part with base 13, exposes the nail groove, and staple 17 is easily put into from the back side, forwards push away from base 13 rear ends then, the clasp nail assembly resets, and finishes the binding action.

In the above embodiments, storage power shell fragment 1, return shell fragment 2 and release return shell fragment 3 all can replace with spring.The particular location of return shell fragment 2 can be provided with flexibly, and the below as front end, centre or the rear end that can be located at storage power shell fragment 1 all can reach the purpose that resets.

The above embodiments only are preferred embodiment of the present utility model, can not limit interest field of the present utility model with this, and therefore, the equivalent variations according to the utility model claim is done still belongs to the scope that the utility model is contained.
