Description

Two-purpose nailing and stapling machine

The utility model relates to the hand-held instrument of stapling together, and is meant the improvement to stapler particularly.

Existing hand-held stapler structure is generally by a loam cake, order needle tray and base plate is formed, and three system articulates with end and forms, wherein ordering the interior leading edge of needle tray is that a pre-fixed gap is arranged, an axostylus axostyle that is coated with spring is then installed in space location after a while, be to have striden the frame of pushing pin on the axostylus axostyle, the frame bottom side trailing edge of pushing pin is connected with in the spring front end, the top side then is connected with to the loam cake bottom side with a pole, be that pull-up loam cake and the related pulling frame of pushing pin retreats during use, and place staple in the needle tray space of ordering of the frame leading edge of pushing pin, decontroling loam cake pusher punch block will be subjected to the elastic force pushing tow of spring and carry out staple near ordering the inboard front end of needle tray, and when applying pressure to loam cake by on the staple that faller gill will be foremost that dashes that covers get by ordering the needle tray space, and, order the pin operation for next and order the lasting tight forward position of staple of carrying out of the frame of pushing pin in the needle tray by staple being ordered in the page with the clamping effect of base plate.

General staple mainly is to be divided into 0.7mm or 0.5mm specification, and existing staple all only can applicable a kind of specification staple, if when on the stapler of 0.7mm specification, using the staple of 0.5mm specification, it often gets two pieces of staples simultaneously, cause waste and influence the effect of having an injection, again if in dress dress 0.7mm staple on the 0.5mm specification staple type, then staple also can be passed through by the space reluctantly, cause card pin fault, obviously general stapler is not can be with the staple of fashionable dress with different size.

The purpose of this utility model provides a kind of dual-purpose nailing and stapling machine, uses this stapler to adorn easily with 0.7mm and 0.5mm staple on a kind of stapler, need not change the stapler of different size.

The utility model adopts following technical scheme: this stapler contains loam cake, order needle tray, base plate, the three does not hold to articulate and forms, order and be provided with spring in the needle tray, axostylus axostyle, lug before and after being respectively equipped with on the axostylus axostyle, ordering needle tray leading edge bottom surface is provided with predetermined towards the pin space, be provided with preformed hole with the needle tray bottom surface of ordering at common stapler different is forward tab rear, in ordering needle tray, also be installed in an inside groove, interior groove bottom is provided with can stretch in the salient point of ordering in the needle tray preformed hole, interior front of the slot upper limb is the chamfering shape, on the axostylus axostyle before and after being set up on the lug block and backstop in one are arranged, between forward tab and middle block, be provided with first spring, between two blocks, be provided with second spring again.When with the small dimension staple, dash the pin space because of what the inside groove shield portions was ordered needle tray, so can hold single staple and pass through, when with big specification staple, then staple is subjected to punching press to be forced down to fall by inside groove leading edge chamfering cunning to force inside groove to retreat, staple can singlely pass through smoothly, uses the different size staple so this stapler can be adorned.

Because the utility model has adopted ordering the needle tray bottom surface and has been provided with preformed hole, and an inside groove is housed in ordering needle tray, its bottom surface is provided with again can stretch in the salient point of ordering the needle tray preformed hole, makes the staple that can adorn the usefulness different size on a kind of stapler.

Below in conjunction with accompanying drawing the utility model being done one describes in detail.

The stapler structure schematic diagram is commonly used by Fig. 1 system.

Fig. 2 is the structural representation of the utility model one preferred embodiment.

Fig. 3 is the illustrative view of the utility model one preferred embodiment.

Fig. 4 is another illustrative view of the utility model one preferred embodiment.

As shown in Figure 2, this stapler contains loam cake 4, order needle tray 5 and base plate 6, the three does not hold to articulate and forms, order and be provided with spring, axostylus axostyle 8 in the needle tray 5, dash pin gap 51 in what order that needle tray 5 inner bottom surface leading edges offer that an about 0.7mm specification staple can pass through, 51 rears are provided with a forward tab 52 in the gap, the rear position then is provided with a back tab 54, is provided with the preformed hole 55 that two length are slightly larger than 0.2mm in the vertical appropriate location, needle tray 5 bottom surfaces of ordering at forward tab 52 rears; One inside groove 7 is loaded on to be ordered in the needle tray 5 and its bottom surface front end has a suitable breach and unlikely block forward tab 52, and vertical appropriate location, inside groove 7 bottom surfaces is provided with two salient points 71 again, and convexedly stretches in respectively and order in needle tray 5 preformed holes 55, and inside groove 7 front end upper limbs are to be chamfering 72 in addition; One axostylus axostyle 8 is worn frame in 54 of forward tab 52 and back tabs, there is block 53 in an appropriate position, axostylus axostyle 8 stage casing, axostylus axostyle 8 then has a backstop 56 in back tab 54 the place aheads,

middle block

53 and 56 of backstops in axostylus axostyle 8 are equipped with second spring 82, its rear end system is butted on backstop 56, its front end then is butted on inside groove 7 rear ends, and inside groove 7 leading edges and the distance of ordering the about 0.5mm of needle tray 5 inboard leading edges maintenances, is equipped with first spring 81 again on axostylus axostyle 8; The frame 73 of pushing pin is to straddle on inside groove 7, and its end face is to be connected with loam cake 4 with a pole 731, and first spring, 81 rear ends are block 53 leading edges in being butted on, and front end then is butted on the frame 73 of pushing pin.

This stapler can be adorned with the general current 0.5mm or the staple of 0.7mm specification, please refer to Fig. 3 as dress during with the staple of 0.5mm specification, be staple can be loaded on to order to straddle in the needle tray 5 on inside groove 7, and by the extremely location of frame 73 ejections of pushing pin, be to press to press loam cake 4 when desiring binding notes, staple 9 is got by inside groove 7 leading edges and the gap 51 of ordering the space of 5 about 0.5mm of needle tray and ordering 5 ends of needle tray towards faller gill 41 by it and to be ordered on page, and the frame 73 of pushing pin will continue just location of ejection staple 9; And when the staple of the 0.7mm specification that changes the outfit, please refer to Fig. 4, staple 9 will be clamp-oned inside groove 7 leading edges and order space between needle tray 5 inboard leading edges along the chamfering 72 of inside groove 7 leading edges is sliding during towards pin, inside groove 7 was pushed and was oppositely oppressed second spring 82 and retreat this moment, and inside groove 7 is ordered 55 restrictions of boxing out of needle tray 5 top because of bottom surface salient point 71 and is caused the about 0.2mm of the amount of retreating of inside groove 7, and makes script be subjected to needle tray 5 gaps 51 of ordering that about 0.2mm is blocked in inside groove 7 front and back all to expose and made the staple 9 of 0.7mm specification be able to pass through towards pin smoothly.
