Description

Stapler

Technical field

The utility model relates to a kind of stapler, relates in particular to a kind of eedle casket of stapling together.

Background technology

Stapler has become indispensable stationery in modern society, and the bookbinding of file, the arrangement of data all must be used stapler; As the patent No. is the structural improvement that the Chinese patent of CN03210638.6 discloses a kind of stapler staple box, staple box is mainly by a seat board, one extension spring, one nail pushing plate, one puts the nail seat, one loam cake and a cover plate are formed, wherein extension spring one end colludes nail seat bottom one side is set, in addition end then to put the nail seat in addition a side stretch through to collude mutually and establish through bending post and nail pushing plate, make nail pushing plate be subjected to the power effect of pulling of drawing of extension spring to keep pushing and pressing forward to be cross-placed on the nail pin of putting on the nail seat, and seat board is put nail seat bottom in order to chimeric sealing, loam cake then is fastened on puts nail seat top, cover plate can make the stapler nail pin nail pushing plate is drawn forward by extension spring by this and pull then in order to the formed opening of movable closed above end face; After staple box nail pin uses, need the dismounting cover plate, just can fill out the nail pin, complicated operation, use inconvenience.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of stapler, only needs the toggle switch button, just can open box for needle or pin, thus staple can put into very easily in the middle frame cover of pin casket, simple to operate, reasonable in design.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of stapler, it includes upper handle, lower handle, pin casket, its spy is being: the switch button is installed in rotation in the pin casket on the frame rear portion, and connections that be clasped mutually of the middle frame cover in switch button and the middle frame, upper handle is equipped with the switch of driving switch button rotation.

Preferably, described switch button front part sides wall respectively forms latch, and middle frame cover two side, rear portion has the draw-in groove that matches with latch.

As improvement, described switch button and upper handle inwall are supported with the switch stage clip, the front end of switch button is provided with a jut, inconsistent with the jut of switch pushing block, be plugged with the switch that slides before and after can be on upper handle in the centre bore of described switch pushing block, switch spring one end buckles on the hook of switch pushing block, and the other end is conflicted and buckled on the hook of upper handle.

At last, described being rotatably mounted adopts axle to connect or the riveted joint connection.Described latch and middle frame cover rear end are to be set to cooperate guiding surface, and middle like this frame cover can lift latch when retreating naturally, realize that latch blocks the draw-in groove action automatically.

Compared with prior art, advantage of the present utility model is: in the pin casket switch has been installed and has been buckled, the switch button is connected with switch by the switch pushing block, pull switch drives switch button rotating opening, and the middle frame cover in the pin casket is withdrawed from, in frame overlaps in can easily putting into staple, frame cover in the propelling fastens the switch button the wherein fixing continuation of frame cover is used, and is simple to operate, rational in infrastructure.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As shown in Figure 1, 2: a kind of stapler, it includes plastics upper handle, lower handle, pin casket, these and tradition are similar, switch button 1 is to be installed in rotation in the pin casket on the frame 7, switch button 1 terminal two side respectively has a through hole 1.1, with upper handle in midair rivet be connected with middle frame 7 with upper handle 3 in the lump, switch button 1 can around upper handle in midair rivet rotate; Switch button 1 front part sides wall respectively forms a latch 1.2, accordingly, middle frame overlaps two side, 6 rear portion and has draw-in groove 6.1, switch button latch 1.2 and middle frame cover draw-in groove 6.1 in the middle frame 7 are that clamping mutually connects and fastens, and switch button 1 upwardly opens, and the draw-in groove 6.1 of frame cover 6 and switch are buckled 1 latch 1.2 and broken away from making, thereby frame cover 6 in can pulling out, switch button 1 fastens downwards, and the draw-in groove 6.1 of frame cover matches with the latch 1.2 that switch is buckled in making, and frame cover 6 is fixed in the middle frame 7 in making; Be supported with switch stage clip 8 between switch button 1 and plastics upper handle 3 inwalls, and switch 4 penetrate in the through hole of plastics upper handle 3 can before and after slide, and be plugged in the centre bore 2.1 of switch pushing block 2, switch 4 is connected with switch pushing block 2, switch spring 5 one ends buckle on the hook 2.3 of switch pushing block 2, the other end is conflicted and to be buckled on the hook 3.1 of plastics upper handle 3, and 1.3 inconsistent cooperations of jut of the jut 2.2 of switch pushing block 2 and switch button 1; At last, latch and middle frame cover rear end is to be provided with the cooperation guiding surface.

Its operation principle is that pull switch 4 drives switch pushing block 2 and slides, make the jut 2.2 of switch pushing block 2 inconsistent, thereby switch button 1 is upwardly opened, frame cover 6 in no longer blocking with switch button jut 1.3, frame cover 6 can withdraw from the middle frame 7, as shown in Figure 4 like this; During openhanded opening, reset force by switch spring 5, switch 4 is prepared to reset, the jut 2.2 of switch pushing block is separated with switch button jut 1.3, and with hand middle frame cover 6 is promoted inward, buckle latch 1.2 on 1 to living switch once more until the draw-in groove 6.1 of middle frame cover 6, and switch button 1 is under the effect of switch stage clip 8, switch button 1 is rotated, frame cover 6 in fastening once more.
